ABSTRACT:
An improved piezoelectric material detector. The material detector (10) has a transducer structure (12) adapted to provide a certain vibration activity. A reset circuit (30) is included to minimize the possibility of false readings. And, a driving circuit (52) and detecting circuit (68) are utilized to drive and sense the presence of a material.
