Hydraulically Amplified Electrostatic Taxels (HAXELs) for Full Body Haptics

Herbert Shea, Edouard Franck Vincent Gustave Leroy

The ability to mechanically stimulate touch receptors over the entire body is a key feature for fully immersive and highly realistic virtual reality experience. Haptic stickers, flexible arrays of HAXELs (hydraulically amplified TAXels), that enable cutane ...

Electrode Impact on the Electrical Breakdown of Dielectric Elastomer Thin Films

Herbert Shea, Fabio Beco Albuquerque

Dielectric Elastomer Actuators (DEAs) enable the realization of energy-efficient and compact actuator systems. DEAs operate at the kilovolt range with typically microampere-level currents and hence minimize thermal losses in comparison to low voltage/high ...

Research data supporting 'Fiber pumps for wearable fluidic systems'

Herbert Shea, Michael James Henry Smith, Vito Cacucciolo

The dataset supporting 'Fiber pumps for wearable fluidic systems', published in Science in March 2023. In this work, we present a fluidic pump in the form of a flexible and stretchable tube. These tubes - or 'fiber pumps' - can generate significant fluidic ...

Fiber pumps for wearable fluidic systems

Herbert Shea, Michael James Henry Smith, Vito Cacucciolo

Incorporating pressurized fluidic circuits into textiles can enable muscular support, thermoregulation, and haptic feedback in a convenient wearable form factor. However, conventional rigid pumps, with their associated noise and vibration, are unsuitable f ...

Fully 3D-Printed, Stretchable, and Conformable Haptic Interfaces

Herbert Shea, Giulio Grasso

Integrating rich cutaneous haptic feedback enhances realism and user immersion in virtual and augmented reality settings. One major challenge is providing accurately localized cutaneous stimuli on fingertips without interfering with the user's dexterity. T ...

Dynamic control of high-voltage actuator arrays by light-pattern projection on photoconductive switches

Herbert Shea, Amir Firouzeh, Edouard Franck Vincent Gustave Leroy, Vesna Bacheva, Aiste Balciunaite

The ability to control high-voltage actuator arrays relies, to date, on expensive microelectronic processes or on individual wiring of each actuator to a single off-chip high-voltage switch. Here we present an alternative approach that uses on-chip photoco ...

Measuring electro-adhesion pressure before and after contact

Herbert Shea, Sylvain Thomas Schaller

Electro-adhesion (EA) is a low-power, tunable, fast and reversible electrically-controlled adhesion method, effective on both conducting and insulating objects. Typically, only the electro-adhesive detachment force, i.e., the force required to separate an ...

Slip Anticipation for Grasping Deformable Objects Using a Soft Force Sensor

Dario Floreano, Herbert Shea, Bekir Aksoy, Krishna Manaswi Digumarti, Euan John Kenneth Judd

Robots using classical control have revolutionised assembly lines where the environment and manipulated objects are restricted and predictable. However, they have proven less effective when the manipulated objects are deformable due to their complex and un ...

Peeling in electroadhesion soft grippers

Herbert Shea, Vito Cacucciolo

Electroadhesion endows robots with super-human abilities: mechanical geckoes that climb vertical walls and soft grippers that grasp the most delicate objects. Based on electrostatics, the adhesion forces are turned on and off by an electrical signal, promi ...

Photoconductive Switching Of A High-Voltage Actuator Array

Herbert Shea, Edouard Franck Vincent Gustave Leroy

We present a method to control individual high-voltage actuators in an array using microfabricated photoconductive switches and a light projection system, thus overcoming the challenges of on-chip control at high voltages. Such switching capabilities go be ...
