Influence of Piezoelectric Actuator Geometry on Resonant Vibrating Amplitude

Yves Perriard, Yoan René Cyrille Civet, Dan Shi

Piezoelectric actuator has been used in different applications because of its compact structure compared to magnetic actuators. This paper reports the influence of piezoelectric actuators geometry on the plate vibrating amplitude. Through a Finite Element ...

A Shoe-Equipped Linear Generator for Energy Harvesting

Dan Shi, Jianxin Shen

In this paper, a linear tubular generator is presented. It is used for an energy harvesting system equipped in a footwear, scavenging power from forward motion during a walk. Configuration of the generator is studied, and geometric optimization by finite-e ...

Modelling and Optimal Design of a Ring-type Structure for the Generation of a Traveling Wave

Yves Perriard, Yoan René Cyrille Civet, Dan Shi

Traveling wave generation in a ring type stator has been studied. The basic working principle to create traveling wave has been modelled by the superposition of two orthogonal standing waves. Theoretical analysis shows that the length to radius ratio affec ...
