Problems solved by technology

However, due to the low electrochemical activity of low-dimensional nano-carbon materials, the deformation ability of the actuator cannot be further improved. However, conductive polymers have high electrochemical activity, but low conductivity, and it is difficult to obtain high-performance IPMC devices.
