Multi-stable actuation apparatus and methods for making and using the same |
摘要 |
Actuator apparatus having a multi-stable element actuated by memory alloy actuating elements. In one embodiment, the multi-stable actuator comprises a bistable (two-state) diaphragm element adapted to alternate between two stable configurations via forces exerted on the diaphragm by more than one memory alloy filaments in response to thermal activation. In another embodiment, the bistable diaphragm of the multi-stable actuator transitions from a first to a second stable configuration via forces exerted by a single filament in response to direct or indirect thermal activation. A portion of the assembly is displaced when the assembly is in the second configuration. The bistable diaphragm transitions back to the first stable configuration via application of mechanical force on a portion of the assembly which was displaced. Methods for making and using the bistable actuator apparatus are also disclosed.
