The EPFL Soft Transducers lab shows here sub-mm thick flexible hydraulically-amplified electrostatic actuators (which we call HAXELs, hydraulically amplified taxels) providing normal and shear forces to the user’s fingertip, hand or arm. Each actuator consists of a fluid-filled cavity whose shell is made of a metalized polyester boundary and a central silicone region. When a voltage is applied to the annular electrodes, the fluid is rapidly forced into the central stretchable region, forming a raised bump. A 6 mm x 6 mm x 0.8 mm actuator weighs 90 mg, generates forces of over 300 mN, out-of-plane displacements of 500 µm (over 60 % strain). Response time is 5 ms.
