Ionic electroactive polymers (iEAPs) actuators have received enormous interest in soft robotics due to relatively large bending strain and fast response time under low driving voltages. While iEAP actuators have developed remarkable bending performances, there are few attempts to realize linear motion at low-voltage and ambient conditions. Herein, we report a novel multilayer design of iEAP actuators showing linear motion by introducing a porous interlayer and two different ion-containing polymer layers. The porous interlayer plays a role of providing large surface areas for effective ion accumulation in electric field. This resultant actuator enables linear motion by electrostatic pressure at the interlayer, which resulted in the impressive linear strain at low-voltages and at ambient conditions. This intriguing result suggests a new avenue for future wearable robotics devices that are operable with portable batteries. |
