Abstract
An SMA actuator includes an SMA element having a first end, a second end, and a central portion therebetween, the SMA element being oriented so that the first and second ends are adjacent one another and attached to one of an anchor interface or payload interface, and so that the central portion of the SMA element is attached to the other of the anchor interface or the payload interface. An electrical shorting device electrically connects the first and second ends, whereby electrical potential may be provided between a first point located between the first end and the central portion and a second point located between the second end and the central portion, thereby causing the SMA element to activate reducing the length of the SMA element. Related latches are disclosed including such actuator, or other simplified or more complex actuators.
