We report classes of electronic systems that achieve thicknesses, effective elastic moduli, bending stiffnesses, and areal mass densities matched to the epidermis. Unlike traditional wafer-based technologies, laminating such devices onto skin leads conformal contact adequate adhesion based on van der Waals interactions alone, in a manner is mechanically invisible user. describe incorporating electrophysiological, temperature, strain sensors, as well transistors, light-emitting diodes, photodetectors, radio frequency inductors, capacitors, oscillators, rectifying diodes. Solar cells wireless coils provide options for power supply. used this type technology measure electrical activity produced by heart, brain, skeletal muscles show resulting data contain sufficient information an unusual computer game controller.
