Piezoresistive Accelerometer

A piezoresistive accelerometer produces resistance changes in piezoresistive materials to covert mechanical strain to a DC output voltage. Piezoresistive accelerometers have a very wide bandwidth which allow them to be used for measuring high frequency and high shock events such as crash testing. Piezoresistive accelerometers can be gas or fluid damped which protects the accelerometer; but also, further widens the dynamic range by preventing the accelerometer from reaching its internal resonant frequency.

Piezoresistive accelerometers are by far the best type for impulse/impact measurements where the frequency range and amplitude are typically high; examples include automotive crash testing, automotive safety testing, safety air-bags & traction control system testing and defence weapons testing.
