Shock Sensor Amplifier (Accelerometer)

View Full Size Image View Original Datasheet Shock Sensor Amplifier (Accelerometer)

A shock sensor is a capacitive piezoelectric element which generates a charge under physical acceleration. This charge can be converted to a voltage and filtered using high valued resistors and a high input impedance CMOS amplifier such as the LTC6081. This circuit has a gain of 100 and output 109mV per g of acceleration.
