5. 4 Silicon Load Cell for Loads up to 1000 kg An array of capacitors is used instead of a single capacitor to compensate for nonhomogeneous force distributions.

6. 5 Micro fluid handling systems By sensing the pressure drop over a fixed hydraulic resistance with use of pressure sensors, the flow through the shunt resistor can be obtained. The monolithic sensor consists of two capacitive read-out pressure sensors, connected by a resistance channel. Because two pressure sensors are used (relative to atmospheric pressure) the sensor can be used both to measure flow-rate as well as pressure

8. 7 Infineon The microphone consists of two chips, the MEMS chip and an application-specific integrated circuit (ASIC), both of which share the same package on a surface-mounted device. The MEMS consists of a rigid, perforated back electrode and a flexible silicon membrane that serves as a capacitor, transforming acoustic pressure waves into capacitive variations. The ASIC detects these variations, converts them into electrical signals and passes them to the appropriate processing devices, such as a baseband processor or amplifier.
