Shape displays are a class of haptic devices that enable whole-hand hapticexploration of 3D surfaces. However, their scalability is limited by themechanical complexity and high cost of traditional actuator arrays. In thispaper, we propose using electroadhesive auxetic skins as a strain-limitinglayer to create programmable shape change in a continuous ("formable crust")shape display. Auxetic skins are manufactured as flexible printed circuitboards with dielectric-laminated electrodes on each auxetic unit cell (AUC),using monolithic fabrication to lower cost and assembly time. By layeringmultiple sheets and applying a voltage between electrodes on subsequent layers,electroadhesion locks individual AUCs, achieving a maximum in-plane stiffnessvariation of 7.6x with a power consumption of 50 uW/AUC. We first characterizean individual AUC and compare results to a kinematic model. We then validatethe ability of a 5x5 AUC array to actively modify its own axial and transversestiffness. Finally, we demonstrate this array in a continuous shape display asa strain-limiting skin to programmatically modulate the shape output of aninflatable LDPE pouch. Integrating electroadhesion with auxetics enables newcapabilities for scalable, low-profile, and low-power control of flexiblerobotic systems.
