AI Technical Summary

Technical Problem

In the prior art, the insulating coating between the support component and the support member of the shape memory alloy (SMA) actuator assembly is prone to wear, leading to short circuits and resistive noise, which affects the reliability and performance of the assembly.

Method used

The support component is physically isolated from the support member and attached with an electrically insulating adhesive to form a continuous gap to prevent current conduction. The support component and the support member extend coplanarly in the same plane to reduce the risk of short circuits.

Benefits of technology

This improves the reliability of SMA actuator components, reduces resistive noise, simplifies the assembly process, and reduces the risk of short circuits and circuit damage.
