The Feasibility Analysis of a Quick Response Artificial Finger Actuated by SMA Springs

Abstract

In this paper, a quick response artificial finger actuated by SMA springs was designed. The SMA springs were heated and cooled by water instead of electricity. A mechanical model, temperature model and SMA phase transformation model were used to predict the movement. The phalanx’s response under different situation was simulated in MATLAB to verify our design and test the feasibility of the quick response of our finger.
