Abstract

To improve performance of thermopneumatic soft actuators, which have recently been developed for various industrial applications, we embedded different nanoscale materials into their elastomer bodies. This yields a significant enhancement in the actuator performance via improving the mechanical and thermal properties of the elastomer bodies. In addition, the use of nanoinclusions diminished losses of the working fluid from the actuators by decreasing vapor leaks through the elastomer body and thus improving longevity. Notably, when using different working fluids with low boiling temperatures, the operating temperature range of the actuators can be lowered and widened. The hybrid approach proposed in this study is expected to advance the industrial feasibility of thermopneumatic actuators.
