Wipers Based on Electroactive Polymeric Actuators

Wiping devices that exploit fingerlike bending motions produced by electroactive polymeric (ionomeric) actuators are undergoing development. These wiping devices function similarly to conventional windshield wipers. However, unlike conventional windshield wipers, these devices contain no motors, gears, or drive linkages; as a result, these devices are relatively simple, compact, and lightweight. Conceived for use in wiping dust off solar cells and windows of scientific instruments to be sent to explore Mars, these wiping devices might be useful for similar purposes on Earth.
