Stretchable dielectrics exploit their inherent elasticity to enable new types of transducers that convert mechanical energy into electrical energy. Electric power can be altered by simply stretching or shrinking a low cost material, and hence is more desirable now-a-days. The challenge of a material to be sustainable for lifelong is a great task for varying environmental conditions. It could be overcome by making functional coatings over the substrate. The challenge includes choosing resins that stretch along with the substrate uniformly without affecting its dielectric properties. In this article, the effect of different polymer coatings over the dielectric elastomer Lycra is investigated. Elastomeric coatings with the polymer resins silicone, TPU and Epoxy were made by doctor blade method. Dielectric properties measurements and Tensile strength tests pointed out the effectiveness of the coated substrates in stretchable RF devices. SEM micrograph images show the sustainability of the resin coated fabric for varying environmental conditions. © 2020 National Institute of Optoelectronics. All rights reserved.
