Abstract: An optical element driving mechanism is provided, and includes a movable portion, a fixed portion, and a driving assembly. The movable portion is used to connect an optical element and is movable relative to the fixed portion. The driving assembly is used to drive the movable portion to move relative to the fixed portion in a first axis. The driving assembly is arranged along a second axis, and the second axis is perpendicular to the first axis.

Abstract: A thin displacement driving device includes a first movable plate, a second movable plate, an axial limiting unit, a first actuator and a second actuator. The axial limiting unit limits the moving direction of the first movable plate and the second movable late. The first actuator has a first shape memory alloy wire coupled to the first movable plate, and the second actuator has a second shape memory alloy wire coupled to the second movable plate. Movement of the first movable plate by the actuation of the first actuator will trigger movement of the second movable plate, and movement of the second movable plate by actuation of the second actuator will trigger movement of the first movable plate.

Abstract: The present invention provides a relay with a shape memory alloy (SMA) wire driven mechanism. Conventional mechanical relays rely on electromagnetic principle to operate. Hence, magnetic fields of electromagnetic relays often interfere with magnetic fields of other electrical components, thus resulting in the components physically interfering with each other. The present invention utilizes the shape memory characteristics of a SMA wire to achieve the purpose of changing the operation of the relay. Specifically, when a SMA wire is heated, it restores to its original shape or original length. Comparing to conventional mechanical relays, the relay provided by the present invention does not magnetically interfere with other electrical components, and thus is able to function effectively. In addition, because the relay of the present invention does not require iron cores or coils, available space therein is increased and may be used to accommodate control circuits with various functions.
