Abstract :
This paper presents a topological-optimization method which applies the theory of ground structure parameterization to design and analyzes a microgripper device. The study defines the compliant design domain as 2000 mum times 2000 mum with a 200 mum thickness, and discusses the effect of different optimization parameters. The driver is an electro-thermal microactuator that can actuate approximately 6000 muN of output force to the displacement amplifier. The microgripper tip deflects up to 18 mum when 1.5 V is applied.
