Piezoelectric beams are widely used in micro-electromechanical systems. At the microscale, influence of size effect on a piezoelectric beam cannot be ignored. In this paper, higher-order elasticity theories considered to predict behaviors micro-structures and size-dependent dynamic model laminated microbeam is established. The governing equations for derived using variational principle. natural...

Abstract This work proposes an examination into the static and dynamic behaviors of in-plane V-shaped microbeam under both electric forces axial loads. The microbeams are actuated with two separate electrodes uniform air gap across their length. effects initial rise DC bias voltage examined while varying loads ranging from compressive to tensile. numerical analysis is based on a nonlinear equat...

The static pull-in instability of beam-type microelectromechanical systems (MEMS) is theoretically investigated. Two engineering cases including cantilever and double cantilever microbeam are considered. Considering the midplane stretching as the source of the nonlinearity in the beam behavior, a nonlinear size-dependent Euler-Bernoulli beam model is used based on a modified couple stress theor...

Single Event Burnout (SEB) in power MOSFETs is of major concern with regard to the suitability of the MOSFET for space missions and other high particle radiation environments. Large efforts have been made to deeply understand this phenomenon, in order to develop power MOSFETs which are less sensitive to SEB [1], [2]. When an ion hits the MOSFET source, amplification of an inherent parasitic bip...
