An ultra-thin electronic device attaches to the skin like a temporary tattoo and measures heart rate and other vital signs without the bulky electrodes used in current hospital monitoring, reports a new study in the 11 August issue of the journal Science.

The device could also potentially be used as an electronic bandage to speed up healing in wounds, burns, and other skin conditions, and it could even provide touch sense to prosthetic devices such as artificial legs or arms.
