Piezoceramic bender transducers for optoelectronic devices

Abstract

This paper presents a bimorph transducer made of a PZT ceramic (titanate zirconate of lead) material, having a high compliance. There are revealed some properties of piezoceramic we have used (which is obtained in the laboratory) and the way to achieve the transducer. The transducer is an electromechanical one and it works on the basis of the reverse piezoelectric effect, converting the electrical power into a mechanical vibration in the range of tens of microns. The low power is fit together with a He-Ne laser in order to increase vibration amplitude and to modify the trajectory of the light beam from distance. This system is very sensitive: it starts vibrating at 5 V voltage. The piezoceramic bender transducers have two major advantages: (1) the ability to generate electrical signals from mechanical and acoustic sources of low impedance; and (2) the ability to develop relatively large motions and low forces with small electrical excitation. This system with piezoceramic bender transducer may be used in medical applications too.
