Untethered Feel‐Through Haptics Using 18‐µm Thick Dielectric Elastomer Actuators

Yves Perriard, Herbert Shea, Yoan René Cyrille Civet, Xinchang Liu, Xiaobin Ji, Vito Cacucciolo

Head‐mounted displays for virtual reality (VR) and augmented reality (AR) allow users to see highly realistic virtual worlds. The wearable haptics that enable feeling and touching these virtual objects are typically bulky, tethered, and provide only low fi ...

Low voltage fast dielectric elastomer actuators

Xiaobin Ji

This thesis contributes to the field of Dielectric Elastomer Actuators (DEAs). DEAs are electrostatically driven soft actuators that are fast, capable of generating large actuation strains, high forces, and present high power density. A wide range of appli ...

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 ...

An autonomous untethered fast soft robotic insect driven by low-voltage dielectric elastomer actuators

Yves Perriard, Herbert Shea, Yoan René Cyrille Civet, Xinchang Liu, Matthias Imboden, Xiaobin Ji, Vito Cacucciolo, Xinru Ji

Insects are a constant source of inspiration for roboticists. Their compliant bodies allow them to squeeze through small openings and be highly resilient to impacts. However, making subgram autonomous soft robots untethered and capable of responding intell ...

Soft tunable diffractive optics with multifunctional transparent electrodes enabling integrated actuation

Samuel Rosset, Herbert Shea, Xiaobin Ji

We present a stretchable tunable transmission grating in which the optical surface serves simultaneously as an electrode for electrostatic actuation. Tunable optics based on elastomers allow for a large tuning range, but integrating an actuator generally s ...
