You could even detect glucose related to stress levels through this 'versatile' wireless e-skin sensor.
"You could put it on your body like a bandage, and paired with a wireless reader on your cellphone, you could wirelessly monitor your pulse, sweat, and other biological signals," added Kim, who is also a principal investigator at MIT's Research Laboratory of Electronics.A highly sensitive piezoelectric material in its pure, defect-free state was peeled away from ultrathin single-crystalline sheets in the latest work by engineers using Kim's old method.
The electrical signal that the sensor automatically provides to the receiver would alter if the circumstances of the skin changed, such as an accelerated heart rate. They strapped the novel e-skin to the wrists and necks of volunteers and used a small antenna held close by to wirelessly record the sensor's frequency without actually touching the sensor itself.
