What if a temporary tattoo did more than decorate your skin — what if it could save your life?
Scientists at the Someya Laboratory at the University of Tokyo have developed a stretchable, breathable electronic and hypoallergenic thin-film sensor that monitors vital signs, such as temperature and pressure, Mashable reported.
Eventually, researchers hope it could help improve the lives of those with prosthetic limbs.
The sensor is made of a nanoscale mesh so thin and lightweight that it's barely noticeable when worn. Wearers who tested out the sensor for a week reported no irritation or other skin issues.
To apply the device, you just spray on some water to dissolve the PVA nanofibers so it'll stick onto the skin, ENGINEERING.com reported.
According to the scientists, the material can be stretched and bent over 10,000 times without breaking.
"It will become possible to monitor patients' vital signs without causing any stress or discomfort," Someya said, according to ENGINEERING.com.
This is just the latest in wearable technology. South Korea scientists have also developed an electronic tattoo that can go on top of or underneath the skin in order to analyze, store, and even send data about the body, such as heartbeat and blood pressure.
