The E-Skin Sensors Can Be Fixed to the Skin Like Temporary Tattoos

Researchers at the University of Tokyo have developed a type of wearable sensors they are calling 'e-skin.' While the idea of having sensors fixed directly to the skin may sound like something out of a science fiction film, it seems that such technology could soon be a reality.

E-skin is an ultra-thin film embedded with functional electronic sensors. These sensors can be laminated to the hand with a clear tape that makes it look as those they are embedded in the skin. The sensors can then project numbers and letters revealing information about the wearer's pulse and blood oxygen levels. The researchers developed the technology to provide consumers with a seamless alternative to bulky smartphones.

While the technology is still in the early stages of development, e-skin demonstrates the future of wearable tech.
