摘要：
Described embodiments provide a shape memory alloy (SMA) cartridge for use in providing controllable compression. The SMA cartridge includes first and second end caps, each of the first and second end caps being coupled to a passive material. One or more SMA coils extend between the first and second end caps. The SMA coils have a trained state and a deformed state, where the SMA coils are in the deformed state when a stimulus is provided thereto and the SMA coils are in the trained state when the stimulus is removed therefrom. The first end cap and the second end cap include a locking mechanism to automatically lock the first and second end caps in a fixed position relative to one another when the SMA coils are contracted.
