A stretchable and breathable form of epidermal device based on elastomeric nanofibre textiles and silver nanowires

Stretchable electronics exhibit compliant mechanical properties for intimate interactions with the human body beyond conventional technologies. Among various systems, electronic textiles that combine electronics with daily garments offer exciting opportunities for wearable applications. The rough surface of the textile structure, however, presents practical challenges towards high-performance electronics. In this study, a breathable and stretchable form of electronic system based on elastomeric nanofibre textiles is reported. The platform employs electrospun nanofibres and silver nanowires to create functional devices, which are termed as electronic nanotextiles. The network architecture offers high permeability to water vapor and comfort-perceptions for epidermal application over the long term. The practical suitability of e-nanotextiles is demonstrated by a multichannel electromyogram-sensing sleeve for measuring muscle activations during hand motions. The developments may stimulate new applications in healthcare monitoring, robotic prosthetics, and textile integrated electronics.
