Abstract
The advantages of pneumatic rubber actuator are good elasticity and light-weight. Thus, it is easy to implement it over the human body. However, conventional one needs a big compressor, which produces portability problem. With tube-free pneumatic actuator it is possible to have a precise control of pressure and its structure is formed by membranes which consist of polymer and platinum. Besides, the flexible electrode structure acts as a polymer actuator, having the potential of hybrid driven. In this paper, a new portable pneumatic actuator based on reversible chemical reaction is proposed and we show that a faster response time is performed by increasing the membrane area ratio.
