Nice.
Scientists have created an inexpensive technique to print “data skin” — soft wearable electronics — paving way for smart tattoos that can be customised and printed at home.
Researchers created a fully functional “data skin” in under an hour. Since the method is based on inexpensive processing tools and materials, the circuits can be produced for less than a dollar.
When wrapped around the fingertip, a “data skin” embedded with an optical pulse oximetry chip can measure heart rate and blood oxygenation, or can bond to the back of the hand to monitor hand gestures.
