Shape memory alloy (SMA) wires, such as nitinol, with diameters less than 8µm (~.0003”) can be produced by the accumulative drawing/rolling and bonding technique, which has been used to make other microscale metallics [1-2]. Further, Nitinol wire or fiber forms have already been explored for use in complex textile production for advanced function . In this working example, as shown in Figure 1 (a,b), over 2,000 NiTi wires with a diameter of 2.5 µm (approx. 0.0001 in) were produced by drawing inside a specially tuned and sacrificial, deformable matrix.
