The goal is to develop a compact, cost-efficient, and autonomous multi-sensor system
The system will offer precise determination of position and orientation
11 project partners from 4 countries
Stuttgart – Micro-electromechanical sensors (MEMS) are becoming increasingly common in everyday applications, enabling us to use electronic devices in significantly smarter, simpler, and more versatile ways. Numerous new applications for smart sensor systems are emerging in the fields of consumer electronics, medical devices, and security technology. These are typically characterized by increasingly challenging requirements regarding cost, size, quality, and energy efficiency. The “9D Sense” collaborative project, which is funded by Germany's Federal Ministry of Education and Research (BMBF) and coordinated by Robert Bosch GmbH, aims to address this challenge by developing a compact, cost-efficient, and autonomous multi-sensor system.
The new multi-sensor system will combine a three-axis accelerometer, three-axis gyroscope, and three-axis magnetometer to offer nine degrees of freedom. It will also include a power supply unit with a thin-film battery and an energy harvester, along with a secure wireless data transmitter. The system will be capable of precisely determining its position and orientation by evaluating the Earth's magnetic field and movement patterns. This method is necessary in situations where no GPS or Galileo signal is available for absolute positioning, for example inside buildings.
Eleven partners from four countries working together The 9D Sense project involves the collaboration of eleven partners from four countries. Four of these partners – Robert Bosch GmbH, the Fraunhofer Institute for Silicon Technology ISIT, the Institute of Micro and Information Technology of the Hahn-Schickard Society, and the Austrian company austriamicrosystems AG – are developing technologies for the sensor system. As part of its work on the power supply aspects, Robert Bosch GmbH is working on a thin-film battery in collaboration with Darmstadt University of Technology, the University of Helsinki in Finland, and the French company Air Liquide. Micropelt and the Institute of Micro and Information Technology of the Hahn-Schickard Society are carrying out research into a suitable power supply unit geared towards a special demonstrator. In their role as end users, Gemalto (France), Otto Bock Healthcare, and Bosch Sensortec GmbH are all contributing demonstrators focused on the fields of security technology, medical devices, and navigation.
Project due to run until November 2014 The project, which is scheduled for completion in November 2014, has received some six million euros of funding from Germany's Federal Ministry of Education and Research (BMBF) as part of the IKT 2020 research program. By promoting research into an innovative, autonomous sensor system and its uses in medical, navigation, and security applications, the BMBF is helping to reinforce and expand German technology companies' leading position in Europe in the field of information and communication technologies.

Stuttgart/Munich/Brussels – The European Patent Office in Brussels announced on Wednesday that Bosch was ranked first for patents in Europe in 2012, with 838 patents granted to the company over the course of the year. The company currently holds a portfolio of more than 90,000 active industrial property rights. In total, Bosch filed more than 4,700 patents in 2012. The European Patent Office regulates the granting of property rights in the 38 member states of the European Patent Organization (EPOrg).
Bosch spends more than 8 percent of its sales on research and development, with R&D expenditure reaching 4.5 billion euros in 2012. More than 42,000 associates work in R&D worldwide, 20,700 of them in Germany. Patents protect the company’s innovations from being imitated, while licensing allows third parties to benefit from Bosch’s technological edge.
From patent to product: a long and winding road Not every good idea leads to a patent, and not all patents go on to become products. The process is generally a long one. “One example is the snap electrode, which is part of our particulate filter for the clean combustion of biomass in the wood-burning stoves of private households,” says Dietmar Steiner, one of the inventors at Bosch.
High-voltage dust-catcher While heating with renewable materials such as briquettes or wood pellets is carbon-neutral, the exhaust gas contains unwanted particulate matter. However, it can be removed by means of a particle separator. Steiner, a physicist in the research department in Schwieberdingen close to Stuttgart, explains how this works: a strong electric field is created in the exhaust pipe, as a result of which free charge carriers attach themselves to the dust. An electrode then attracts the charged dust particles, which stick to it.
Longer maintenance cycles thanks to snap electrodes At some point, the electrode is so covered in dust that it has to be cleaned. Steiner and his project team first began to devise solutions in 2006. The dusty electrode can be briefly shaken by a bimetal element that folds over (“snaps”) as the stove heats up. As a result, the dust is shaken off the electrode into the stove’s ash pan.
“Our aim was to have a filter that required maintenance only twice a year, and we have achieved this,” Steiner says. The filter prevents more than 85 percent of particulate matter from being emitted. By using mass-produced parts that Bosch is able to manufacture in large numbers and to high quality standards, costs were significantly reduced. Lower limits on particulate matter will take effect in Germany from 2015. The new filter will make it possible to comply with them.
The first prototypes were built in 2006, and a patent was filed in 2008. In 2010, the snap electrode patent was published. It was then legally granted in 2011. A number of other companies in the heating industry have expressed interest in the technology, and licensing negotiations are currently underway.

New design methodology paves the way for innovative sensors and actuators
Robots will be able to see and feel more effectively in future
Stuttgart – The design of micro-electromechanical systems (MEMS) is about to undergo a technological revolution: experts from research institutions and industry are investigating entirely new methods for developing MEMS. They are working together in the research project known as “Circuit Diagram-Based Design of MEMS for Applications in Optics and Robotics” – or MEMS2015 for short. This project is funded by the Federal Ministry of Education and Research (BMBF) and coordinated by Robert Bosch GmbH. The aim is to develop the first ever universal design methodology for MEMS to plug the gaps between electronics and mechanics design, manufacturing, and subsequent integration into products.
MEMS are tiny components that require a minimum of space to measure and electronically process parameters such as acceleration, pressure, distance, temperature, light, or chemical concentrations. With their sophisticated, compact sensor and actuator systems, MEMS can for instance be used to ensure that airbags are inflated promptly before a car is involved in a collision, to measure blood pressure or oxygen content in intensive care applications, or to enable digital cameras to eliminate camera shake.
Potential 50 percent increase in the market for MEMS The new development methods for MEMS will allow innovative sensor and actuator systems to be developed – providing robots, for instance, with more effective sight and touch in the future. Using a type of modular system, the MEMS2015 researchers aim to plug the gaps between chip and sensor manufacturing on the one hand and the subsequent integration of the modules into products on the other. This will substantially increase the opportunities for widespread use of MEMS in the professional and security-relevant segments. The new methods will also allow small and medium-sized enterprises to design MEMS and integrate them into their products much more often, as well as in a wider range of configurations than at present. What is more, the potential market for MEMS stands to increase by up to 50 percent as a result.
Projecting images directly onto the retina These new development methods for MEMS will pave the way for entirely new solutions in the leading-edge applications of optics and robotics. This opens up the prospect of the wide-ranging use of micromirror arrays, similar to the devices already being used in projectors. This technology allows images to be projected directly onto the retina using special glasses. In robotics, force sensors and profilometers can be developed that analyze surfaces even more accurately than before, or that simulate an extremely precise sense of touch. The project findings are being verified as part of the project on the basis of real MEMS prototypes which, in turn, serve as demonstrators.
“The project opens up innovations in mechanical engineering and process plant engineering by using powerful sensor and actuator systems based on groundbreaking MEMS and chip technologies,” says Dr. Mirco Meiners, the project coordinator for MEMS2015 who works in the Bosch Automotive Electronics division. “The clear focus of funding from Germany’s Federal Ministry of Education and Research (BMBF) helps companies maintain their lead in innovation for key technology topics and develop new innovative, complex products.”
“The MEMS2015 project raises the bar when it comes to the quality and especially the productivity of MEMS design,” says Prof. Dr. Ralf Sommer, the scientific director of the Institut für Mikroelektronik- und Mechatronik-Systeme gemeinnützige GmbH, one of the eight partners in the project. “Basic concepts such as circuit diagram-based design, which are already successfully used in microelectronics design, are now being transferred to MEMS design. This offers users enormous advantages: for one thing, MEMS2015 facilitates new highly complex products, such as micromirror arrays, and speeds up the process of bringing them to market. For another, the project will allow us in the long run to produce a Lego-brick-style design. This will above all benefit small and medium-sized enterprises, allowing them to put together their own individual, tailor-made solutions in a flexible modular MEMS and electronics system.”
Eight partners from research and industry The MEMS2015 research project, which has a three-year term and around 3.5 million euros in funding from Germany’s Federal Ministry of Education and Research (BMBF) as part of the German government’s High-Tech Strategy and the ICT 2020 development program, brings together the potential of eight partners from research and industry: Cadence Design Systems GmbH, Carl Zeiss SMT GmbH, Institut für Mikroelektronik- und Mechatronik-Systeme GmbH, Robert Bosch GmbH, the Technical University of Munich, TETRA Gesellschaft für Sensorik, Robotik und Automation mbH, the University of Bremen, and X-FAB Semiconductor Foundries AG. The edacentrum in Hannover is responsible for project management for MEMS2015.
