The creators of electronic tattoos and flexible battery cells have decided to go even further and have developed electrosensors that are embedded directly into human skin.
As the research team of Rogers at the University of Illinois has found, when the electronic grid is applied to the top layer of the skin, the sensor remains flexible, compact and perfectly tolerates the natural curves of the skin.
At the moment, the field of application of such sensors is mainly limited to medical purposes. They will be able to control the moisture and temperature of the skin, pick up electrical signals from the muscles, and also record a person's brain activity.
Given the massive interest in wearable gadgets for monitoring the state of the human body, the development of electronic tattoos is only a matter of time. The capabilities of subcutaneous sensors are impressive. Whether we are ready for it or not, it looks like the future is near.
