Bio-integrated systems with stretchable designs for skin-mounted wearable health monitoring

We present ultrathin, flexible and stretchable epidermal health monitoring devices that contain physiological sensors, an analog front end processor, a core microprocessor, flash memory module, rechargeable battery, and a wireless communication (Bluetooth low energy) module. The system is mechanically matched to the Young´s modulus of human skin and designed to record heart rate, electromyography signals, activity, respiration and sleep quality to facilitate continuous (electro-)physiological data recording outside of the hospital setting.
