TiNi Alloy is developing the technology of heat actuated shape-memory alloy (SMA) thin film microdevices. Shape-memory alloys undergo a crystalline phase change when heated or cooled above ambient, and this phase change is accompanied by a change in elastic modulus. The premier application of these microactuators is in miniature valves, but other potential applications include miniature connectors, switches, and end effectors for microrobotic manipulators.
