Analysis of flexible thin actuator using gas–liquid phase-change of low boiling point liquid

Abstract

In our previous study, the flexible thin actuator using gas-liquid phase-change of a low boiling point liquid that can generate large force was proposed and tested. The tested actuator is an envelope-type actuator that is made of laminating plastic sheets, low boiling point liquid, and a flexible heater. In this chapter, the analytical model of the flexible thin actuator was proposed and tested. The system parameters of the actuator were also identified. As a result, it was confirmed that the proposed analytical model can predict the behavior of the real actuator.
