Epidermal Electronics

Electronic tattoos with thickness, effective elastic modulus, bending stiffness, and areal mass density matched to the epidermis have been developed. Laminating such devices onto the skin leads to conformal contact and adequate adhesion in a manner that is mechanically invisible to the user. Such devices have been demonstrated for noninvasive monitoring of EEG, EKG and EMG. It also represents a platform technology for potential incorporation of temperature sensors, strain gauges, LED, solar cells, antennas and so on. Watch the Video
