Stretchable and Multimodal All Graphene Electronic Skin

A transparent and stretchable all-graphene multifunctional electronic-skin sensor matrix is developed. Three different functional sensors are included in this matrix: humidity, thermal, and pressure sensors. These are judiciously integrated into a layer-by-layer geometry through a simple lamination process. Electronic skins (E-skins) are flexible circuitry matrices in which each sensor cell can transduce external stimuli on epidermis to electronic signals. E-skins are potentially useful in the fabrication of wearable human-machine interfacing devices, remote real-time health monitoring, implantable prosthetics, and multifunctional smart skins.1-6 For example, pressure-sensitive rubbers integrated with organic…
