The Influence of Static Pre-stretching on the Mechanical Ageing of Filled Silicone Rubbers for Dielectric Elastomer Applications

The Influence of Static Pre-stretching on the Mechanical Ageing of Filled Silicone Rubbers for Dielectric Elastomer Applications

Abstract Dielectric elastomer (DE) pre-stretching is a key aspect of attaining better actuation performance, as it helps prevent electromechanical instability (EMI) and usually lowers the Young's modulus, thus leading to easier deformation. The pre-stretched {DE} is not only susceptible to a hi...
