Monitoring of composite structures using a network of integrated PVDF film transducers

Thomas Gmür, Joël Cugnoni, Enrique René Guzman Solares

Aiming to reduce costs, polyvinylidene difluoride (PVDF) film patches are an emerging alternative to more classic piezoelectric technologies, like ceramic patches, as transducers to measure local deformation in many structural applications. This choice is ...

Variable Stiffness Actuator for Soft Robotics Using Dielectric Elastomer and Low-Melting-Point Alloy

Dario Floreano, Herbert Shea, Samuel Rosset, Jun Shintake, Bryan Edward Schubert

A novel variable stiffness actuator composed of a dielectric elastomer actuator (DEA) and a low-melting-point-alloy (LMPA) embedded silicone substrate is demonstrated. The device which we call variable stiffness dielectric elastomer actuator (VSDEA) enable ...

Rollable Multisegment Dielectric Elastomer Minimum Energy Structures for a Deployable Microsatellite Gripper

Herbert Shea, Volker Gass, Samuel Rosset, Jun Shintake, Muriel Richard, Irina Gavrilovich

Debris in space presents an ever-increasing problem for spacecraft in Earth orbit. As a step in the mitigation of this issue, the CleanSpace One (CSO) microsatellite has been proposed. Its mission is to perform active debris removal of a decommissioned nan ...

Soft Pneumatic Actuator with Adjustable Stiffness Layers for Multi-DoF Actuation

Jamie Paik, Amir Firouzeh, Marco Salerno

The soft pneumatic actuators (SPAs) are a solution toward the highly customizable and light actuators with the versatility of actuation modes, and an inherent compliance. Such flexibility allows SPAs to be considered as alternative actuators for wearable r ...

High-resolution, large-area fabrication of compliant electrodes via laser ablation for robust, stretchable dielectric elastomer actuators and sensors

Herbert Shea, Samuel Rosset

A key element in stretchable actuators, sensors and systems based on elastomer materials are compliant electrodes. While there exist many methodologies for fabricating electrodes on dielectric elastomers, very few succeed in achieve high-resolution pattern ...

Optimization of the force and power consumption of a microfabricated magnetic actuator

Herbert Shea, Juan José Zarate

The force (F) and the power consumption (P ) of a magnetic actuator are modeled, measured and optimized in the context of developing micro-actuators for large arrays, such as in portable tactile displays for the visually impaired. We present a novel analyt ...

Soft piezoresistive sensor model and characterization with varying design parameters

Jamie Paik, Amir Firouzeh, Antoine Foba Amon Junior

Recent robots target safety, reconfigurability and interactivity by addressing the “softness” of the hardware either by endowing additional degrees-of-freedom or through inherent compliancy. These robots require distributed sensing with flexibility and sof ...

Injection Device

Yves Perriard, Romain David Besuchet

An injection deviee for injecting injection material, comprising: an elastic deformable element (3) able to exert a pushing force on a piston (20) of a syringe (2) so as to eject a quantity of injection material out of the syringe (2); a stopper ( 4) for r ...

DEA for soft robotics: 1-gram actuator picks up a 60-gram egg

Dario Floreano, Herbert Shea, Stefano Mintchev, Samuel Rosset, Jun Shintake, Bryan Edward Schubert

We introduce a soft actuator for grippers using DEA capable of bending actuation. The actuator is also able to generate the electro-adhesion by the fringe field formed at the edges of the electrodes. The adhesion improves the holding force and ensures the ...

Soft Actuation of Structured Cylinders through Auxetic Behavior

Pedro Miguel Nunes Pereira de Almeida Reis

We introduce a new class of soft actuators based on the buckling of locally patterned elastic cylindrical shells that can be designed to reversibly achieve flexural or twisting motion. Depressurizing our samples allows for tunable and controllable motion. ...
