Tiny high-tech helpers for vehicles and smartphones MEMS sensors are the smallest products Bosch manufactures. Their first application was in automotive electronics and Bosch has been producing these precision sensors for use in vehicles since 1995. A yaw-rate sensor that records the rotary movements of the car around its vertical axis is at the heart of ESP, for example, and today each modern vehicle is home to up to 50 MEMS sensors. In an automotive context, the key considerations for MEMS are their reliability and robustness, as the sensors have a direct impact on the safety of road users. Size and energy consumption are much less important factors. But the picture is


quite different when it comes to smartphones or games consoles, which is why Bosch shrunk its sensors over the years to just one fiftieth of their former size. The latest generation of these sensors unites a host of functions in a casing measuring just a few square millimeters. Meanwhile the sensors’ energy consumption has been reduced by a factor of 100. Of all the suppliers in the market, Bosch is the only one producing sensor types for so many different applications. The company holds or has applied for a total of well over 1,000 patents, thereby safeguarding its innovative strength.
