A new dimension of acceleration: Bosch launches world’s smallest MEMS accelerome ...

Las Vegas, Nevada / Reutlingen, Germany – Space is at a premium in hearables, smartwatches and other portable consumer products, and all components must be as small as possible. At the same time, OEMs are demanding plug-and-play step-counters and other sensors with built-in features that enable easy implementation without detailed application knowledge. To meet these challenges, Bosch Sensortec has announced the BMA530 and BMA580, the world's smallest MEMS accelerometers. Both devices include built-in features making them easy to design with. BMA530 tracks activities with its step counter and is especially suitable for wearables, and BMA580 targets hearables with voice activity detection.Compared to Bosch's current generation accelerometer (BMA253), the BMA530 and BMA580 have a 76 percent smaller footprint and have been reduced in height from 0.95 mm to 0.55 mm. This size reduction is achieved with an innovative Wafer Level Chip Scale Package (WLCSP). The small size of the accelerometers makes them easy to place on a PCB, and their integrated features make them easy for design engineers to integrate into their portable products. "The demand for tiny sensors with ever-increasing performance is growing as the industry moves towards more stylish and minimalist designs that require smaller sensors," said Stefan Finkbeiner, General Manager and CEO of Bosch Sensortec. "The new BMA530 and BMA580 provide an ultra-compact, fully-featured solution to meet this demand." The demand for tiny sensors with ever-increasing performance is growing as the industry moves towards more stylish and minimalist designs that require smaller sensors. The new BMA530 and BMA580 provide an ultra-compact, fully-featured solution to meet this demand. ...said Stefan Finkbeiner, General Manager and CEO of Bosch Sensortec. Bone conduction for reduced power consumption The BMA580 provides innovative voice activity detection and an advanced feature set for hearable devices. Typically, microphones in hearables consume a lot of power because they need to be always-on to listen for voice activity. Instead, the BMA580 uses bone conduction to detect the vibration of the user’s voice and then wakes the microphone from sleep – for an overall power saving. No other sensor on the market combines bone conduction with this miniature sensor size. The BMA580 enables user interaction with a hearable in response to the user tapping the device, for example to answer or end a call. The sensor’s software includes an algorithm that can distinguish between single, double and triple taps. In addition to wearables, the new BMA530 acceleration sensor is ideal for gesture recognition in toys, fall detection in laptops and other devices, and power management functions such as putting a smartphone to sleep when it is not moved. The new accelerometers offer multiple power modes and automatically switch from low-power to high-power modes to extend battery life. They offer a flexible set of connectivity options, including an I3C® interface. Availability: The new acceleration sensors from Bosch Sensortec can be ordered at our distribution partners from Q1 2024 onwards.

More than meets the eye: Bosch enables the next generation of smartglasses

At CES® in Las Vegas, Nevada, Bosch Sensortec launches an innovative optical Light Drive system for smartglasses. The Bosch Smartglasses Light Drive module is a sole source, all-in-one technology stack consisting of MEMS mirrors, optical elements, sensors, and onboard processing. This integrated solution delivers a clean visual experience with bright images that are always in focus – even in direct sunlight.The disruptive Bosch Light Drive technology revolutionizes all-day wearables with perceived total transparency for the user, and with radical social acceptance because it is nearly invisible to others. Additionally, the technology can also be applied to optimize performance of waveguide systems for which integration packages are in development. There is no externally visible display or integrated camera, the two pitfalls that have alienated users of other smartglasses technologies. The smaller size allows designers to overcome the bulky, cumbersome characteristics of many of today’s smartglasses. For the first time, a turnkey system enables smaller, lighter, more stylish smartglasses designs that meet the visual and comfort needs of everyone. The tiny module is also big news for those who wear eyeglasses for vision correction - a significant market, since six out of ten people use corrective lenses every day. The Smartglasses Light Drive system is the smallest and lightest product on the market today and is, therefore, able to turn almost any regular spectacles into smartglasses. By eliminating distracting phone usage, smartglasses can help improve driving safety and reduce the impulse of users to constantly check their mobile devices for notifications or messages....says Dr. Stefan Finkbeiner, CEO of Bosch Sensortec. Bosch Sensortec’s innovative Smartglasses Light Drive solution paves the way for a day without digital fatigue. The system displays the perfect balance of just-in-time hands-free information in a minimalist format, making it ideal for applications including navigation, calls, and notifications such as alarms, calendar reminders, and messaging platforms such as WhatsApp and WeChat. Everyday note-based information like to-do and shopping checklists are exceptionally convenient. To date, these applications have been primarily restricted to devices with physical displays like smartphones or smartwatches. Smartglasses minimize socially unacceptable behavior such as obsessive phone checking, and help improve driver safety by providing hands-free, transparent heads-up navigation directions. The new technology promises to broaden the scope and availability of apps and information, coupled with instant access to relevant data, social media, and intuitive control of audio playback. Innovative technology in a tiny package A microelectromechanical system (MEMS) based collimated light scanner inside the Bosch Smartglasses Light Drive module scans a holographic element (HOE) that is embedded in the lens of the smartglasses. This HOE redirects the light beam onto the human retina surface, directly painting a picture that is always in focus. The technology enables hands-free, secure viewing of practically any data from a connected mobile device, such as a paired smartphone, overlaid in a comfortable viewing position. The projected high-resolution image is crisp, bright, private, and clearly visible even in direct sunlight thanks to its adaptive brightness. The Bosch Light Drive technology is compatible with curved and corrective lenses, making this new tech appealing and available to users who already wear prescription glasses. Older competitor display technologies are hindered by a haze or rainbow glare called stray light that is visible when the system is switched off. The Bosch Light Drive technology provides pleasing all-day optical transparency with minimal stray light sensitivity, meaning the view is always crystal clear, and that distracting internal reflections are a thing of the past. Smallest Smartglasses Light Drive solution on the market The new complete turnkey Light Drive system is the smallest comparable solution available on the market, delivering a depth reduction of 30 percent compared to existing solutions. It measures approximately 45-75 mm x 5-10 mm x 8 mm (L x H x W, depending on customer integration) and weighs less than 10 grams. This makes it easy for glasses manufacturers to flexibly reduce the width of the glasses frame to create a stylish design, and eliminate the visibly chunky design of first-generation smartglasses. Social acceptance and broad adoption have the potential to make retinal Light Drive technologies the next boom for manufacturers of consumer electronics display devices. End-to-end solution for smartglasses manufacturers Bosch Sensortec provides a turnkey Light Drive solution – designed and built in-house to ensure consistent high quality, reliability, and performance, whilst being able to quickly respond to market and customer demands for product modifications. Bosch Sensortec is the only end-to-end system provider of such retinal Light Drive technology and can further leverage this position by offering an extensive range of complementary devices and solutions. The smartglasses module is enriched by several sensor solutions, such as Bosch’s smart sensor BHI260, the barometric pressure sensor BMP388, and the BMM150 magnetometer. The sensors enable intuitive user interface features such as multi-tap functions on the frame to improve convenience while operating the glasses. The Bosch Smartglasses Light Drive solution will be available in 2021 to high-volume manufacturers as part number BML500P.

Manufacturers can now design smaller and more accurate hearables with lower power consumption while increasing their performance. Hearables include devices such as standard or sports earbuds, hearing aids or high-end hearables like gaming headsets. Bosch Sensortec's many years of experience in the areas of signal processing and ultra-low power MEMS sensor design are key to helping manufacturers create the next generation of hearables....Dr. Stefan Finkbeiner, CEO of Bosch Sensortec "Bosch Sensortec's many years of experience in the areas of signal processing and ultra-low power MEMS sensor design are key to helping manufacturers create the next generation of hearables," says Dr. Stefan Finkbeiner, CEO of Bosch Sensortec. "The new BMA456 is a great example of how Bosch leverages its experience and know-how, adapting proven wearable technologies for the developing hearables market." Accelerometers have played a pivotal role in extending the possibilities for hearables, enabling sensing for initiating voice assistant systems, head gesture control and body movement tracking and more....Peter Cooney, Founder and Research Director, SAR Insight & Consulting Hearables are a fast-growing market segment, and a major growth driver in the wearables space. Based on data from SAR Insight & Consulting, the market for True Wireless Earbuds (TWE) is expected to grow to almost 180 million units by 2023. "Accelerometers have played a pivotal role in extending the possibilities for hearables, enabling sensing for initiating voice assistant systems, head gesture control and body movement tracking and more," says Peter Cooney, Founder and Research Director, SAR Insight & Consulting, "As the TWS market continues to expand rapidly, there are many interesting opportunities for sensor vendors to enable interesting and innovative products offering substantial market potential". A broad range of hearable features The new BMA456 accelerometer variant integrates hearable-specific gestures for intuitive user interactions such as tap, double-tap and triple-tap. Thereby, the user can, for example, conveniently control playback, manage the volume, or accept and decline calls. All of these functions are carried out within the BMA456 itself, thus eliminating the need to wake up a power-hungry application processor. These features and its extremely low height of 0.65 mm make the BMA456 a perfect fit for Truly Wireless Stereo (TWS) headsets and midrange hearables used for entertainment and in everyday life. Another feature is power management. To limit power consumption, the BMA456 accelerometer accurately distinguishes between motion and no-motion, switching itself and the device to a low-power mode. In addition, the sensor enables low-power in-ear and out-of-ear recognition that could, for example, instantly pause playback when the user removes the hearable from their ear and set the entire system to sleep mode. The BMA456 also includes a low-power step counter and step detector that is specifically optimized for hearables. In combination with the sophisticated activity recognition feature that detects walking, running and standing still, the BMA456 hearable variant is a perfect fit for sports and activity-tracking hearables that operate with smartphones or stand-alone. Manufacturers can flexibly configure the default parameter sets of these features to improve the performance of their devices. The sensor’s low noise of 120 µg√Hz, low offset of ±20 mg and low TCO of 0.35 mg/K further improve the accuracy of the device.

Bosch announces virtual touchscreen on every surface for smart homes and IoT

At CES® in Las Vegas, Nevada , Bosch Sensortec announced the BML100PI, an Interactive Projection Module that enriches smart homes with a virtual touchscreen on every surface – turning ordinary shelves into personal assistants. With this Interactive Projection Module any regular shelf can easily be transformed into a personal assistant for the user, greatly enhancing the level of convenience in people’s daily lives.... Dr. Stefan Finkbeiner, CEO of Bosch Sensortec The BML100PI module provides a complete, ready-to-use solution for interactive projection, enabling highly flexible virtual touchscreens. A generated laser beam creates a focus-free image on any surface and then scans it line-by-line to detect any gestures or finger movements. No calibration or adjustment is required for accurate gesture and touch recognition. Bosch Sensortec’s Interactive Projection Module provides a touchscreen with a highly intuitive user experience for any smart home appliances as a fully flexible alternative compared to a static, physical screen. Personal assistants in smart homes Home device manufacturers can use the BML100PI to create 'smart shelves' consisting of several simultaneous projections on the individual shelves for example in fridges, cupboards, kitchen cabinets or wardrobes. One module can provide touchscreen functionality on up to six different surfaces. For example, a single module can project a weather forecast, the user’s individual daily schedule as well as reminders of upcoming events on to a wardrobe. This information is processed and appropriate clothing is recommended to match the weather forecast and/or planned personal activities. The created look can then be shared with friends via social media – directly on the shelf surface. If an item of clothing is missing or in the laundry bin, the smart shelf can suggest new clothing for the user to order in an online fashion store or it can schedule a date for the laundry service, which is directly synced with the user’s calendar. "With this Interactive Projection Module any regular shelf can easily be transformed into a personal assistant for the user, greatly enhancing the level of convenience in people’s daily lives," said Dr. Stefan Finkbeiner, CEO of Bosch Sensortec. The BML100PI is a compact plug-and-play solution that enables manufacturers of smart home appliances and furniture to create entirely new, exciting use cases. This creates a huge potential for product differentiation for manufacturers. An allrounder for all environments One key feature is that the module can project a sharp image on to any type of surface, regardless of whether it is dark, colored, wet, stepped or curved. It can thus provide interactive projection e.g. in bedrooms, home appliances or kitchen gadgets where suitable projection surfaces are often lacking. Compact module – easy to integrate in any smart home appliances The BML100PI offers low power consumption of typically 2 W. With its footprint of only 47 mm x 43 mm it is smaller than a credit card. This enables manufacturers to simply integrate it into practically all new and existing smart home appliances – significantly easier than existing projection or display solutions on the market. In addition to the BML100PI module, Bosch Sensortec offers the BML100P variant, which provides the same projection features but without the touch functionality. Availability The BML100PI and BML100P will be available in the second quarter of 2020.

Reutlingen / Munich, Germany – At electronica Munich, Bosch Sensortec announces the BHI160BP, the industry’s first Position Tracking Smart Sensor that utilizes integrated inertial sensors to improve GPS location tracking. Pedestrian position tracking is a crucial application for mobile applications; unfortunately, GPS modules can rapidly drain a device’s battery capacity – especially when the battery is as small as in wearable devices....Dr. Stefan Finkbeiner, CEO of Bosch Sensortec Always-on position tracking When used with a GPS or GNSS module, the BHI160BP enables users to take full advantage of pedestrian position tracking with up to 80% saving in system power consumption compared with a typical GNSS-only solution, without compromising on accuracy. Users benefit from a greatly extended battery life and longer charging intervals for wearable applications such as smartwatches and fitness trackers and other mobile devices such as smartphones or hearables. This new position tracking approach is set to enable a new class of compact devices with even smaller batteries. The BHI160BP tracks a person’s position by intelligently applying an inertial sensor based algorithm for Pedestrian Dead Reckoning (PDR). To maintain accuracy, it calculates the user’s relative location based on data collected from the inertial sensors and then re-calibrates itself every few minutes to obtain the absolute position provided by the GNSS/GPS module. This means that the GNSS/GPS module can be kept in sleep mode for most of the time, which drastically reduces a device's power consumption and extends its operating time. "Pedestrian position tracking is a crucial application for mobile applications; unfortunately, GPS modules can rapidly drain a device’s battery capacity – especially when the battery is as small as in wearable devices," says Dr. Stefan Finkbeiner, CEO of Bosch Sensortec. "Our new Position Tracking Smart Sensor solves this problem and enables users to navigate reliably while extending the operation of GPS tracking in their devices from several hours up to several days." Straightforward integration The position tracking capability provided by the BHI160BP also means that a device can maintain solid accuracy even when the GNSS signal is blocked or weak, e.g. near tall buildings or indoors. This ensures accurate pedestrian navigation at all times, even in shielded indoor areas such as subways. The BHI160BP is a new member of Bosch Sensortec’s BHI160 family and adds application-specific functionality for position tracking. It provides a ready-to-use solution that can be quickly and easily integrated into a system design without requiring an update to a new GNSS module, thereby significantly cutting time to market. While the current configuration is optimized for use with GNSS receivers (such as GPS), the BHI160BP can also support most of the common global localization technologies. As well as improving localization, the BHI160BP can also serve to handle gesture recognition and 3D orientation, with 3D calculations performed by the sensor itself rather than by an application processor. Wide range of features and functionalities The new BHI160BP draws only 1.3 mA in active operation mode and is the industry’s lowest-power solution that integrates the Fuser Core (MCU) and a 6-axis Inertial Measurement Unit (IMU). Additionally, the Position Tracking Smart Sensor offers a variety of customized virtual sensors, such as a calibrated accelerometer, orientation and wake up gesture, within a single device. Furthermore, the BHI160BP can be extended by connecting additional physical sensors, such as a magnetometer, over a secondary interface. The new BHI160BP comes in a compact 3 x 3 x 0.95 mm3 LGA-package and is pin-to-pin compatible with the BHI160.

Bosch launches BMI260 family: new generation of IMUs optimized for smartphone ap ...

Reutlingen, Germany – Bosch Sensortec launches the BMI260 family, a new generation of high-performance MEMS Inertial Measurement Units (IMUs) targeted at smartphone applications. The family comprises of three sensors – BMI260, BMI261 and BMI263 – which deliver an extensive range of features, including full Android TM compliance, an I3C SM interface, and support for sensor synchronization.The new IMUs are equipped with a high-performance accelerometer and provide highly accurate step counting, motion detection and precise data to support indoor SLAM (Simultaneous Localization and Mapping). In addition to increased performance, the BMI260 family offers significantly reduced power consumption for extended smartphone battery life. Thanks to low-latency, OIS (optical image stabilization) and EIS (electronic image stabilization) support, the BMI260 family enables much sharper pictures and ultra-smooth video stabilization. "Our next-generation BMI260 family of IMUs builds upon the rock-solid foundation put in place by the very successful BMI160," says Dr. Stefan Finkbeiner, CEO of Bosch Sensortec. "These new IMUs deliver enhanced accelerometer performance, an extensive range of powerful features and interfaces, and, importantly, Component Retrimming (CRT) for motionless gyroscope self-calibration. End users can now look forward to many new features and a much faster, smoother, and essentially flawless experience.” Broad range of features The BMI260 is the base variant, combining Bosch Sensortec’s high-end accelerometer performance with Bosch’s automotive-proven gyroscope technology. Its high robustness against temperature fluctuations and PCB stress enables extremely precise acceleration sensing. The BMI261 variant is fully Android TM compliant and specifically optimized for always-on smartphone gesture and activity recognition. The BMI263 is Bosch Sensortec’s first product to be fully compliant with the latest MIPI I3C SM standard and supports both asynchronous and synchronous timing control. Each device includes a primary and secondary interface that can be configured independently in I²C or SPI. This enables dual SPI configuration, camera modules or auxiliary sensor connections, for example a magnetometer. Finally, the entire BMI260 family enables extended support for data synchronization. Built-in gyroscope self-calibration Each of the new IMU devices includes the industry’s first motionless Component Retrimming (CRT) feature for built-in gyroscope self-calibration. This eliminates the need to calibrate the sensitivity of the MEMS gyroscope using a rotation stimulus. This plug-and-play feature promises to significantly accelerate testing and manufacturing processes to further reduce cost and time-to-market for device makers. Enabling sharp pictures and videos with OIS/EIS The new family of IMUs boasts powerful OIS and EIS features. Excellent, low latency (e.g. Google Daydream View compliant), minimal group delays (max. about 600 µs) and high-precision time stamps (accuracy about 40 µs) substantially improve photo and video quality for end users. Dual SPI interfaces enable a single IMU to serve two SPI-based modules, supporting stereo or 3D camera operation. Using the BMI260 family on the mainboard enables congruent HMI and OIS functions, such as stabilized panorama photo panning and action video tagging. Ultra-low power consumption Power consumption is kept very low, helping to noticeably prolong smartphone battery life and reduce charging cycles for end users. At a full output data rate (ODR) of up to 6.4 kHz, the typical current draw for both the accelerometer and gyroscope is kept at a level of 700 μA. By enabling high output data rates with low current consumption, smartphone manufacturers can avoid compromising their designs with unpleasant aliasing effects – an effect that causes different signals to become indistinguishable when sampled at lower ODRs. The BMI260 IMU family provides an intelligent power management system enabling all always-on features to run inside the ultra-low power domain of the IMU. Therefore, the host application processor has to wake up only on rare, dedicated occasions, enabling a maximized idle period for the main processor. For example, the system can run reliable gesture and activity recognition features at power draws of merely 30 μA. The new BMI260 family offers a compact package measuring only 2.5 x 3.0 x 0.8 mm3. The IMUs are pin-to-pin compatible with its predecessor BMI160. BMI260 and BMI261 are available for high-volume production. Samples of BMI263 are now available on request.
