Piezoelectric polymer impact detector

Abstract

In an example, an impact detector may include a sensor mounting bracket, a piezo film sensor assembly, and an interface circuit. The sensor mounting bracket may be attached to an impact sensing object. The piezo film sensor assembly may be coupled to the sensor mounting bracket. The interface circuit may be configured to obtain one or more generated signals from the piezo film sensor assembly. The interface circuit may be configured to reduce a first amplitude associated with a noise signal and may be configured to amplify a second amplitude associated with an impact signal. The impact signal may occur in response to a force being applied to the impact sensing object.
