Abstract By imitating the behavioral characteristics of some typical animals, researchers develop bionic stepping motors to extend working range piezoelectric materials and utilize their high accuracy advantage as well. A comprehensive review driven by is presented in this work. The main parts motors, including feeding module, clamping other critical components, are introduced elaborately. We c...

Composite materials are a very important class of engineering materials with great properties and applications in a variety of complex structures. The correct design of such structures requires adequate analysis and, in particular, adequate and accurate models for simulation with numerical tools. Piezoelectric materials can convert mechanical energy into electric energy and vice-versa and are b...

The mechanical-electrical coupling properties of piezoelectric semiconductors endow these materials with novel device applications in microelectromechanical systems, sensors, human-computer interfaces, etc. When an applied strain is exerted on a piezoelectric semiconductor, piezoelectric charges are generated at the surface or interface of the semiconductor, which can be utilized to control the...

This note addresses the concept of wave energy conversion by means of piezoelectric material. The ocean surface waves represent an important source of energy power. A multiphysics simulation is used to focus on different aspects, namely the free surface wave, the fluid-structure-interactio, the mechanical energy input to the piezoelectric material and finally the electric power output using an ...
