Abstract
A conducting composition includes a topological polymer (e.g., a polyrotaxane polymer) and poly(3,4-ethylene-dioxy thiophene):polystyrene sulfonate (PEDOT:PSS). Devices may include a conducting layer including the conducting compositions, e.g., a device comprising a conducting layer, wherein the conducting layer includes a polyrotaxane polymer and a PEDOT:PSS array. The devices are useful in bioelectronics, including high-resolution electrophysiological monitoring of deformable tissues and localized neuromodulation for high-precision control of individual muscle activities.
