sciencehabit writes "Researchers have developed ultrathin electronics that can be placed on the skin as easily as a temporary tattoo (abstract). The scientists hope the new devices will pave the way for sensors that monitor heart and brain activity without bulky equipment, or perhaps computers that operate via the subtlest voice commands or body movement. The devices can even be hidden under actual temporary tattoos to keep the electronics concealed, giving them potential applications for espionage."
