Abstract. Results of experimental determination of characteristics of piezoelectric drives based on thin-film lowvoltage piezoelectric actuators are presented. Estimations are carried out of potentially achievable values of technical characteristics of the drives for micro-movements of operated modules of precision devices. Problems of realization of high-precision and stable-working micro-movers are discussed.
Keywords: piezoelectric actuators, piezoelectric drive, characteristics of piezoceramics.
