. . "For example, if the transducer 100 is mechanically stretched by external forces to a thinner, larger area shape such as that shown in FIG. 1B, and a relatively small voltage difference is applied between electrodes 104 and 106, when the external forces are removed the transducer 100 will contract in area between the electrodes to a shape such as in FIG. 1A. Stretching the transducer generally refe" . .
