Glove- and Sleeve-Format Variable-Friction Electrostatic Clutches for Kinesthetic Haptics

Clothing with integrated high-force actuators enables wearable haptics for immersive virtual reality (VR) and enables soft exoskeletons for rehabilitation or human augmentation. Electrostatic clutches (ESClutches) offer a very-low-energy solution to block ...

Wearable Soft Technologies for Haptic Sensing and Feedback

Herbert Shea, Ronan Julien Hinchet

Virtual reality (VR) and augmented reality (AR) systems have garnered recent widespread attention due to increased accessibility, functionality, and affordability. These systems sense user inputs and typically provide haptic, audio, and visual feedback to ...

Multimode Hydraulically Amplified Electrostatic Actuators for Wearable Haptics

Herbert Shea, Ronan Julien Hinchet, Edouard Franck Vincent Gustave Leroy

The sense of touch is underused in today’s virtual reality systems due to lack of wearable, soft, mm-scale transducers to generate dynamic mechanical stimulus on the skin. Extremely thin actuators combining both high force and large displacement are a long ...

TacTiles: Dual-Mode Low-Power Electromagnetic Actuators for Rendering Continuous Contact and Spatial Haptic Patterns in VR

Herbert Shea, Juan José Zarate, Ronan Julien Hinchet

We introduce TacTiles, light (1.8g), low-power (130 mV), and small form -factor (1cm(3)) electromagnetic actuators that can form a flexible haptic array to provide localized tactile feedback. Our novel hardware design uses a custom 8 -layer PCB, dampening ...

Triboelectric‐TFT Flip‐Flop for Bistable Latching of Dielectric Elastomer Actuators

Herbert Shea, Danick Briand, Rubaiyet Iftekharul Haque, Alexis Pierre Henri Marette, Xiaobin Ji, Ronan Julien Hinchet

A high‐voltage flip‐flop combining two self‐powered soft sensors with a flexible high‐voltage thin film transistor (HVTFT) is reported, and is used to electrically latch dielectric elastomer actuators (DEAs) in zero and high‐strain states. Two touch‐actuat ...

High Force Density Textile Electrostatic Clutch

Herbert Shea, Ronan Julien Hinchet

Clutches are key elements for blocking or coupling motion in wearable systems such as soft exoskeletons, haptic clothing, and rehabilitation equipment. Electrostatic clutches (ESclutches) are compact and light, making them particularly well-suited for wear ...

DextrES: Wearable Haptic Feedback for Grasping in VR via a Thin Form-Factor Electrostatic Brake

Herbert Shea, Ronan Julien Hinchet

We introduce DextrES, a flexible and wearable haptic glove which integrates both kinesthetic and cutaneous feedback in a thin and light form factor (weight is less than 8g). Our approach is based on an electrostatic clutch generating up to 20 N of holding ...
