It is considered that when temperature begins to fall down under Ms, martensite and the untransformed mother-phase are in a kind of thermobalance. We try to use the equations in marten- site transform to get the mathematical relationship between the dynamics of the microclamp and the temperature, also including some useful results for design and fabrication of the microclamp. We hope these results will form the work principle base for SMA microclamp.
