AI Technical Summary

Technical Problem

When the existing SMA actuator assembly provides rotational movement control of the movable part, the number of electrical connections and control channels are too large, and the complexity is high.

Method used

An SMA actuator assembly is designed to reduce the electrical connection and control channels required to control the rotational position of the movable portion relative to the support structure by electrically connecting a plurality of SMA elements together.

Benefits of technology

By reducing the number of electrical connections and control channels, the control logic is simplified, the reliability and efficiency of the system are improved, while reducing manufacturing complexity.

Abstract

A shape memory alloy (SMA) actuator assembly comprises: a support structure (3); a movable portion (100) movable relative to the support structure; a first plurality of SMA elements (55a) electrically connected together arranged to apply a torque to the movable portion for rotating the movable portion relative to the support structure about the main axis (P) in a first direction; a second plurality of SMA elements (55b) electrically connected together arranged to apply a torque to the movable portion for rotating the movable portion relative to the support structure about the main axis in a second direction, where the second direction is opposite the first direction.
