Electroactive Polymer Artificial Muscles (EPAMs) are a new actuating/motion technology based on polymers that react to electricity. The new actuators are useful across applications where motors are not as efficient or are simply not feasible. The basic EPAM is a rubber sheet made of a custom-formulated elastomer, explains Ilya Polyakov, a senior mechanical engineer at Artificial Muscle, Inc., creators of the EPAM. The polymer is applied so that electrodes plate the rubber sheeting on both...
