3 Sensing element
The sensing element shall mean the acoustic sensor consisting of a conductive movable
plate and a fixed plate placed in a tiny silicon chip. This sensor transduces the sound
pressure into the changes of coupled capacity between those two plates.
Omron Corporation supplies this element for STMicroelectronics.
