Japenese researchers have created a stretchy, ultrathin electric "skin" that can read and display the wearer's heartbeat. It could prove useful for emergency prevention: readings can be sent to either a cloud or memory device for assessment.

Professor Takao Someya and his team from the University of Tokyo have developed a device that can be stuck on the body like a second skin, reported AFP.

By using nanomesh electrodes and stretchable wiring, the patch features a micro LED array that can bend with the skin and display simple, animated imagery, such as an electrocardiogram waveform.

The patch can be stretched to a maximum of 45% of its original length, and it's created to be much more resistant to wear and tear than previous skin displays.

Wearables are getting more powerful (and often sleeker in design) with each new iteration that hits the market: from wearable MRI devices (which some propose could allow us to read minds) to our first real glimpse into human sleep patterns, to bendable batteries that could drastically improve implants, wearables propelling medicine into the future. It can monitor health data and send and receive messages.
