Advancing dielectric elastomers in soft robotics: project BROADCAST's multidisciplinary approach

Abstract

Project BROADCAST will deliver a new class of powerful soft, biomimetic systems that can interact with their environment in a save, bio-inspired way. The approach is based on major advances in the production technology of dielectric elastomers (DE) circuitry, new soft electronic materials, and new approaches in signal processing. BROADCAST investigates multi-functional DEs that drive robotic structures based on bio-inspired electro-mechanical control strategies such as central pattern generators, autonomous peristalsis, locomotion and similar others. This requires new materials for flexible electrodes and sensors that provide curtailed electrical and electro-mechanical properties, such as Young's modulus, conductivity and piezoresistivity. These materials will provide new features in robotics such as sensorless system where the DEA will act both as an actuator and a sensor by providing continuous feedback in real-time.
