Micro-tweezers Based on V-Beam Thermal Actuator

Abstract

This paper presents some modeling aspects regarding an application of the V-beam thermal actuator in micro-manipulation. The influence of the Micro-tweezers’ geometrical parameters on the output gripping force is analyzed in order to provide the basis on the future design of some task oriented structures. Numerical simulations are performed on the complete V-beam thermal actuator - Micro-tweezers assembly in order to evaluate the proposed model. The results provided by the two approaches on this problem proved to be in good agreement. As referred to in the paper, the V-beam thermal actuator’s behavior as a separate entity has been previously investigated by both numerical and experimental methods.This paper presents some modeling aspects regarding an application of the V-beam thermal actuator in micro-manipulation.
