An “electronic tattoo” could herald a revolution in the way patients are monitored and provide a breakthrough in computer gaming, say US scientists.
They used the device, which is thinner than a human hair, to monitor the heart and brain, according to a study in the journal Science.
The sensor attaches to human skin just like a temporary tattoo and can move, wrinkle and stretch without breaking.
Researchers hope it could replace bulky equipment currently used in hospitals.
A mass of cables, wires, gel-coated sticky pads and monitors are currently needed to keep track of a patient’s vital signs.
Scientists say this can be “distressing”, such as when a patient with heart problems has to wear a bulky monitor for a month “in order to capture abnormal but rare cardiac events”.
