Abstract
A micro-dimensioned shape memory alloy composite composed of a thin film of shape memory material and a substrate film. The substrate film does not require further processing and thus the composite can be used as a switch without removing any portion of the substrate on which the SMA is deposited. It is also shown that more effective switches can be manufactured by including as a component of the composite a stress compensating film.
