Printed electronics open way for electrified tattoos and personalized biosensors

Electrical engineers have devised a fully print-in-place technique for printable electronics that is gentle enough to work on delicate surfaces ranging from paper to human skin. This can be accomplished without additional steps to bake, wash or powder-coat materials. The advance could enable technologies such as high-adhesion, embedded electronic tattoos and bandages with patient-specific biosensors.
