Electroadhesion (EA) is an appealing approach for applications in soft robotics and flexible grippers due to reversibly modulated adhesion to surfaces. It can be generated by applying electric field through sub-surface interdigitated electrodes in a reversible manner. Here, we demonstrate stretchable and locally manipulated EA by utilizing liquid metal electrodes with spider web morphologies. The liquid metal (EGaIn, Eutectic Gallium-Indium) is a soft and fluid conductor, thus the interdigitated liquid metal wire patterned into the microchannels of PDMS (polydimethyl siloxane) can maintain the EA performances, while the PDMS substrate is strained. The EA forces can also be manipulated by changes of the electrode geometries such as width and density. This ability allows to locally tune EA force within a single film by applying a constant voltage. This work could serve multiple applications for stretchable electronics and artificial skin for soft robotics applications. |
