Ultrasoft Liquid Metal Elastomer Foams with Positive and Negative Piezopermittivity for Tactile Sensing

Yegor Piskarev, Yang Li, Michael Dickey, Jianhang Yang

Soft, capacitive tactile (pressure) sensors are important for applications including human-machine interfaces, soft robots, and electronic skins. Such capacitors consist of two electrodes separated by a soft dielectric. Pressing the capacitor brings the el ...

Taming the viscoelastic creep of dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Alexandre Poulin

We present a simple open-loop method to suppress the viscoelastic drift of dielectric elastomer actuators (DEAs). Viscoelastic creep is one of the drawbacks of DEAs, especially when made with acrylic elastomer membranes (VHB). This leads to a time-dependen ...

Modelling of current and temperature effects on supercapacitors ageing. Part II: State-of-Health assessment

Mario Paolone, Dimitri Torregrossa

This second part of the paper proposes a model for predicting the State-of-Health (SOH) of electrochemical double layers supercapacitors (SCs) during combined high-pulsed power cycling and high-temperature life endurance stresses. The evolutions of the SC ...

Children’s Peer Assessment and Self-disclosure in the Presence of an Educational Robot

Pierre Dillenbourg, Shruti Chandra, Séverin Lemaignan, Ana Paiva

Research in education has long established how children mutually influence and support each other's learning trajectories, eventually leading to the development and widespread use of learning methods based on peer activities. In order to explore children's ...

Elastomeric Electronic Skin for Prosthetic Tactile Sensation

Stéphanie Lacour, Hadrien Olivier Michaud, Aaron Powers Gerratt

This report demonstrates a wearable elastomer-based electronic skin including resistive sensors for monitoring fi nger articulation and capacitive tactile pressure sensors that register distributed pressure along the entire length of the fi nger. Pressure ...

Can a Child Feel Responsible for Another in the Presence of a Robot in a Collaborative Learning Activity?

Pierre Dillenbourg, Shruti Chandra, Séverin Lemaignan, Ana Paiva

In order to explore the impact of integrating a robot as a facilitator in a collaborative activity, we examined interpersonal distancing of children both with a human adult and a robot facilitator. Our scenario involves two children performing a collaborat ...

Self-sensing dielectric elastomer actuators in closed-loop operation

Herbert Shea, Samuel Rosset

Because of their large output strain, dielectric elastomer actuators (DEAs) have been proposed for tunable optics applications such as tunable gratings. However, the inherent viscoelastic drift of these actuators is an important drawback and closed-loop op ...
