BBC has posed the question “Could electric tattoos be the next step in body art?” They highlight the work that Dr. Nanshu Lu and Dr. Hyoyoung Jeong created and Dr. Lu’s outlook for the future of this technology. The article goes on to say “Prof Lu isn’t only interested in medical applications. She suggests that future electronic tattoo designs could light up to reveal when someone’s heart is beating faster.
