Wearable antennas can suffer from a variety of mechanical deformations that are induced by the body dynamic. The paper analyses how these complex deformations impact the performance of a flexible antenna operating in the 5-6 GHz band. The Green Coordinates spatial manipulation technique is used to generate a range of complex two-dimensional deformations, namely spherical, saddle, and twisting deformation. Generating full geometries is a key enabler in this study. The results offer valuable insight to the stability of antenna performance under insitu deformations.
Flexible interconnects are essential components for signal transmission for foldable and wearable electronics. As such they are exposed to a variety of mechanical deformations that can degrade their electromagnetic performance. This paper analyses the impact of bending and twisting deformations on the transmission properties of a variety of commercially available polymer and elastomer based interconnects and compares to the performance of flat interconnects fabricated on rigid substrates. The analysis of the impact of deformations also takes into account the degradation in the conductivity of the printed lines due to reported mechanical deformations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
