ABSTRACT
The article discusses engineers' efforts to use smart materials to develop actuators that can fit into smaller spaces, save weight, and react more quickly. It notes General Motors' (GM) use of shape-memory-alloy (SMA) wires to create movement in small spaces and the Honda-supported research to incorporate piezoelectric devices into seat belts. It also discusses Etrema's application of Terfenol-D magnetostrictive actuators and CSA Engineering's use of a 40-millimeter piezoelectric stack.
