Abstract: Systems and methods for a wearable system that monitors various biomarkers with a 3D-printed wearable electronic skin. Specifically, the wearable system is a 3D-printed epidermal wearable microfluidic electronic skin that may be composed of a combination of multidimensional nanomaterials, polymers, and hydrogels. The epidermal wearable microfluidic electronic skin may be integrated with sensors, electrodes, microfluidics, and a processor to collect and analyze molecular biomarkers of biofluid samples on the user's skin, while simultaneously analyzing the user's physiological biomarkers to conduct a health status assessment or gather health monitoring/surveillance metric.

Abstract: Systems and methods for a self-powered wireless wearable sensor system include a freestanding triboelectric nanogenerator (FTENG), used as a power source for a wearable sensor. The FTENG includes stator panels and corresponding slider panels with a grating pattern. Movement, such as cardiovascular exercise causes the slider panel(s) to slide across the stator panel(s) inducing a charge and powering a wearable device sufficiently to support data transmission and continuous monitoring. An integrated self-powered wireless wearable sensor system includes a microfluidic sweat sensor patch which may be connected to lower-power wireless sensor circuitry for regulating power efficiently and is powered by the FTENG.
