Abstract

A flexible array of high-force and high-stroke mm-scale actuators for wearable haptics will be presented. The soft actuators are capable of both of out-of-plane motion and in-plane motion, allowing the user to feel both normal forces and shear forces from the same active bump. Combining features of DEAs and HASEL devices, each actuator consists of an oil-filled cavity made of a metalized polymer perimeter and a central elastomer region. When a voltage is applied to the electrodes, the fluid is rapidly forced into the central region, forming a bump. Each actuator generates forces of up to 300 mN and displacements of up to 500 µm (60% strain), with a response time of under 10 ms. The 5x5 array is low-profile (<1 mm thick), lightweight (90 mg per actuator) and is suitable for integration in a haptic glove, sleeve or bracelet. It can also be used as a dynamic graphical display for blind or visually impaired users.
