MEMS sensors

In a microcontroller the typical semiconductor can only control current and voltages. In a Micro-Electro-Mechanical-System (MEMS), additional mechanical structures are used. This means that three-dimensional structures are usually added to the starting material silicon by etching processes. This allows the design of membranes (WSEN-PADS) or movable finger structures (WSEN-ITDS).

Block Diagram

The best way to explain the function of MEMS sensors is a block diagram. The biggest difference to conventional (analog) sensors is that not only the actual measuring cell but also the complete processing can be integrated to achieve a very small sensor system. This eliminates any analog data processing on application level and a digital signal can be used directly by a microcontroller. Since a complete system is combined in one component, a complete factory calibration is also possible.
