Electrostatic repulsive out-of-plane actuator using conductive substrate

A pseudo-three-layer electrostatic repulsive out-of-plane actuator is proposed. It combines the advantages of two-layer and three-layer repulsive actuators, i.e., fabrication requirements and fill factor. A theoretical model for the proposed actuator is developed and solved through the numerical calculation of Schwarz-Christoffel mapping. Theoretical and simulated results show that the pseudo-t...

Skeletal Muscle is a Biological Example of a Linear Electro-Active Actuator

Skeletal muscle represents a classic biological example of a structure-function relationship. This paper reviews basic muscle anatomy and demonstrates how molecular motion on the order of nm distances is converted into the macroscopic movements that are possible with skeletal muscle. Muscle anatomy provides a structural basis for understanding the basic mechanical properties of skeletal muscle—...

Robust Control of an Electrostatic Microelectromechanical Actuator

A continuing trend these days is the use of micro-electro-mechanical actuators with electronic circuitry to fabricate MEMS devices such as micro-switches, hard disks, optical micro-mirrors ... One of the problems with the electrostatic MEMS actuator is that when an electrical voltage is applied to these devices, the micro-actuators undergo a residual vibration before reaching their permanent po...

Antennas Made of Transparent Conductive Films

Abstract— The radiation characteristics of two kinds of antennas made of transparent conductive films are investigated: a planar inverted-F antenna (PIFA) and a monopole antenna. These antennas are designed to work at 2.4 GHz and their performances are compared with each other for several films with different sheet resistivities. Wire-grid models based on the moment method are applied for the n...
