Abstract
A modified shape memory alloy fibers exhibits a rapid twitch response under timulation by an action potential such as the heating effect of an electromagnetic pulse; in particular the relaxation time of the twitch response is considerably shortened as compared with that of the unmodified fibers; the modification is achieved by simultaneous application of a stretching force and a short, powerful electromagnetic pulse effective to bring about contraction resulting from the shape memory and change material properties; this application is carried out a plurality of times.
