The aim of this paper is to experimentally show that polyvinylidene fluoride biaxially oriented in bimorph configuration is a suitable flexural traveling wave device. Piezoelectric ceramic is promising, however the lack biocompatibility is the main drawback for biomedical micro-electromechanical system. A prototype of 20 mm diameter was designed, constructed, and tested via an optical method. A first investigation was performed on two standing waves which were excited to generate the traveling wave.

Abstract
The aim of this paper is to experimentally show that polyvinylidene fluoride biaxially oriented in bimorph configuration is a suitable flexural traveling wave device. Piezoelectric ceramic is promising, however the lack biocompatibility is the main drawback for biomedical micro-electromechanical system. A prototype of 20 mm diameter was designed, constructed, and tested via an optical method. A first investigation was performed on two standing waves which were excited to generate the traveling wave. The findings of amplitude and phase have revealed a B31vibration mode at 7.2 kHz and a maximum amplitude of roughly 40 nm. The flexural traveling wave was confirmed experimentally.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
