On Piezoelectric Harvesting Technology

Abstract

In recent years, significant progress has been made with in-deep application of piezoelectric harvesting energy technology. To make the technology development more convenient, a comprehensive review on application of piezoelectric harvesting technology is made in the paper. Piezoelectric harvesting devices as power source from vibration, human motion and so on are expounded. The technology would bring fast increasing in systems of micro wireless sensor, integrated systems and self-power MEMS.

Piezoelectric atomization of liquids with dynamic viscosities up to 175 cP at room temperature

“…An ultrasonic motor uses two vibrations of the same frequency and different phases perpendicular to each other, so the surface particles of the stator of the ultrasonic motor form an elliptical trajectory, thus driving an object to move by friction [38] . Due to its simple structure, small size, light weight, fast response time, low noise level, large torque at low speed, good control characteristics, self-locking characteristic under power failure, freedom from magnetic field interference, and accurate motion [39] , [40] , ultrasonic motors are widely used in the automotive, aerospace, precision manufacturing, optical scanning, biotechnology and medicine [41] , [42] , [43] , [44] , [45] , [46] , [47] , and energy harvesting fields [48] , [49] , [50] , [51] .…”
