Abstract
An actuator comprises an impervious deformable bladder containing a fluid whose boiling temperature is equal to a set cut-in temperature. On reaching that temperature, the fluid within the bladder will be vaporized, cause the bladder to expand, and produce accordingly a displacement movement which can be utilized for a variety of purposes.
