Title:
ACTUATOR AND ACTUATOR DRIVE METHOD
Document Type and Number:
WIPO Patent Application WO/2024/101137
Kind Code:
A1
Abstract:
The present technology relates to an actuator and an actuator drive method, which are designed such that an actuator (SMA actuator) using shape memory alloys (SMA) can be cooled by an independent cooling mechanism. A wire is formed of a shape memory alloy, the wire is inserted into a hollow part of the cylindrical member, and a refrigerant, which is a fluid, is stored in the hollow part.
