Abstract

In spite of the simple fabrication process, Ionic electroactive polymers (iEAP) work based on a very complex actuation mechanism that is originated in the movement of unequally sized ions through the ionic channels inside the polymer membrane. Such a sophisticated mechanism leads to nonlinear behavior of iEAPs while subjected to electric stimulation and makes their response unpredictable. Here we propose a real-time measurement technique for tracing the movement of ions inside the polymer membrane to better estimate the behavior of the iEAPs during actuation. To do so, a highly flexible and porous electrode is needed to be incorporated into the polymer membrane thus it neither blocks the ions’ path nor restricts the mechanical deformation. Using such an electrode one can measure the internal electrical potential of the membrane, during actuation, to monitor the potential alteration caused by the ions’ migration inside the membrane.
