AI Technical Summary
Technical Problem
SMA actuator assemblies in miniature applications are limited by stroke and actuating force, necessitating longer or thicker wires that increase cost, size, and power consumption.
Method used
An actuator assembly design incorporating a body portion, force-modifying element, and coupling link that leverages a lever system to amplify input force, allowing for a longer body portion that extends along the majority of a major side, enhancing stroke and force without increasing size or power.
Benefits of technology
The design provides increased stroke and actuating force while maintaining compact size and reducing power consumption, suitable for miniature applications.
