A Wearable Soft Tactile Actuator With High Output Force for Fingertip Interaction
IEEE Access, 2021 This paper reports a soft fingertip-mountable tactile actuator based on a Dielectric Elastomer Actuator (DEA), which exhibits high output force over a wide frequency range with a lightweight and soft structure. DEA is a soft actuator characterized by its

Large actuation and high dielectric strength in metallized dielectric elastomer actuators [PDF]
Applied Physics Letters, 2012 Metal films are seldom used as compliant electrodes for dielectric elastomer actuator (DEA) because they tend to restrain deformation of soft dielectrics. This work showed that silver film electrodes formed by electroless deposition (ELD) are indeed stretchable, and the DEA using ELD silver electrodes is able to generate an actuation up to 50% areal ...

Advanced Healthcare Materials, EarlyView.Deployable medical devices typically need external stimuli to trigger deployment. However, external stimuli are difficult to supply within tissues. Here, we describe a strategy to deploy small‐scale structures into soft tissues after insertion without the need for any stimulus. We demonstrate deployment within a tissue phantom.
