TL;DR: A flexible and sensitive textile-based pressure sensor is developed using highly conductive fibers coated with dielectric rubber materials that exhibits superior sensitivity, very fast response time, and high stability when applied to make smart gloves and clothes that can control machines wirelessly as human-machine interfaces.

TL;DR: A bioinspired microhairy sensor is developed to enable ultraconformability on nonflat surfaces and significant enhancement in the signal-to-noise ratio of the retrieved signals.

TL;DR: The first stretchable energy-harvesting electronic-skin device capable of differentiating and generating energy from various mechanical stimuli, such as normal pressure, lateral strain, bending, and vibration, is presented.

TL;DR: In this paper, the development of high performance light-emitting devices with flexible and stretchable form factors is described. But the development is mainly achieved by replacing the rigid materials in the device components with flex...

TL;DR: Various approaches for fabricating intrinsically stretchable electronic materials are presented, including the blending of electronic fillers into elastomer matrices, the formation of bi-layered heterogeneous electronic-layer and elastomers support-layer structures, and modifications to polymeric molecular structures in order to impart stretchability.
