P3.2 - Low-cost Thick-film Sensor Based on Piezoelectric Effect for Ballistic Application

D. Crescini
A new type of pressure sensor is presented which is based on the piezoelectric effect principle in screen printed and fired thick-films. The sensitive element, consisting of a circular piezoelectric layer sandwiched in two conductive layers, is screen printed and fired over an alumina substrate, 2 mm thickness and 3 mm diameter. The sensitive element has a structure of a plane capacitor with the piezoelectric film as dielectric and the two conductive layers, based on...
