Abstract

The use of a semi-numerical model in order to optimize a magnetic micro-switch is proposed. It relies on a flexible sizing environment for which novel models based on sums, surface, and volume integrals necessary to express magnetic phenomena have been developed. Then, corresponding software components have been generated. This environment is applied to optimize a bi-stable out-of-plane magnetic micro-switch. The optimized micro-switch is dedicated to be used in optical micro-scanner application. Its main characteristics are high displacement (in excess of 100mum), low switching time, and current consumption (300mA). Results demonstrate a performing and generic way for fast design by optimization
