This paper presents a novel in-silico tool for the design of complex multilayer Dielectric Elastomers (DEs) characterised by recently introduced layer-by-layer reconfigurable electrode meso-architectures. Inspired cutting-edge experimental work at Clarke Lab (Harvard) Hajiesmaili and (2019), this contribution introduces approach underpinned diffuse interface treatment electrodes, whereby spatia...

The present study describes the effect of NCO/OH and triol/diol ratios on the mechanical properties of Nitro functionalized Hydroxyl-terminated polybutadiene (Nitro-HTPB) elastomers. The progress of the cure reaction of Nitro-HTPB and toluene diisocyanate (TDI) is evaluated by following up the variations in the IR absorption bands of the NCO stretching and the CO ...

A dielectric elastomer can undergo a large deformation when it is subjected to an applied electric field. As result, finds potential usage in artificial muscles, soft robotics, and medical devices. However, current elastomers suffer from low constants (e.g., <4.5). Grafting highly dipolar groups onto has been proved be efficient method improve the constant thus electroactuation property. grafti...

Dielectric elastomer (DE) transducers are polymer-based devices consisting of an insulating elastomeric membrane with compliant electrodes on both sides, forming a flexible capacitor that can work as actuator or sensor. In this report, new direct and maskless method is presented to pattern-compliant metallic specially developed for DE applications. Highly conductive stretchable nickel-based fir...

Dielectric elastomers are soft actuators, made of an elastomer membrane sandwiched by compliant electrodes. Because their high energy density and quick response, they well suited for dynamic applications such as loudspeakers. Thanks to progress in the manufacturing process dielectric electrode shape can be patterned very diverse shapes. In this study, we focus on relation between dynamical acou...
