Light operated mechanical actuator |
摘要 |
An actuator is comprised of a main body, an inner space filled with an amount of thermally expansive gas and having a first portion in the form of a shallow configuration with an opening oriented toward one side of the main body, a second portion and a bottleneck passage located therebetween, a membrane in the form of a thin film connected to the side of the main body for closing the opening of the first portion of the inner space, a substance for converting the light into heat, and a guide device for guiding light into the second portion of the inner space. Upon an unexpected application of an external force on the thin film, the deformation of the thin film is limited at minimum by being supported by the bottom surface of the first portion. This ensures the prevention of the breakage of the thin film.
