For all ratios of PEDOT PSS (15—35 wt%) the electrical resistance is compatible with standard measurement devices, thus, for the electromechanical characterization we use only sensors made from 20 wt% PEDOT PSS solution. 

In order to characterize an IPMC actuator, it is necessary to electromechanically characterize it on the basis of actuation and force measurements. These methods are described in Chap. 10, IPMCs as EAPs How to Start Experimenting with Them of this book. Here, the teehniques used to characterize an IP and its plated electrodes are described (Rajagopalan et al. 2010 Wang et al. 2010 Panwar et al. 2012 Wang et al. 2014). These are also important for developing new actuator materials.

The experimental setup for measuring eleetromechanical performance of an IPMC actuator consists of a clamp to mount the IPMC sample, a data recording device (e.g., digital oscilloscope or computer equipped for data acquisition), a function generator, a current amplifier, a force sensor, and a laser displacement sensor or a video camera (Figs. 4 and 5). The process diagram of electromechanical characterization is given in Fig. 6.
