IPMCs as a artificial muscle — •Parisa Bakhtiarpour, Masoud Amirkhani, and Othmar Marti — Institute of Experimental Physics, Ulm University, Albert-Einstein-Allee 11, 89081 Ulm, Germany

IPMCs(Ionic Polymer Metal Composite) are classified as EAPs(electro active polymers), that their properties change by electrical stimulation. The shape and size of these polymers alter when electrical voltage apply to their opposite interfaces. In additional, IPMCs bending can produce electrical signal in back movement. By patterning the metal electrodes during the IPMCs sample fabrication, movement with multiple degree of freedom is possible. The performance of IPMC can be control and monitor with several sensing methods such as surface resistivity connected in bridge configuration.

In this research, we developed Simultaneous actuating and sensing methods for IPMCs sample. We consider the sample as variable resistance which displacement of sample could be detected by proper electrical circuit design. The benefit of this method is reducing the noise and also possibility of measurement for each part of patterned sample independently.
