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.

3D-printed epidermal wearable microfluidic electronic skin for machine learning-powered multimodal health surveillance

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.

Systems and methods for powering autonomous sweat sensor

An auto-powered biosensor capable detecting a target molecule, and a method of powering the same, wherein the biosensor is fabricated with a microfluidics layer, a multimodal sensing layer comprising a biofuel cell and an electrode, and a logic circuit that may include a processor and non-transitory memory with computer executable instructions embedded thereon.

Auto-powered synthetic skin

A biosensor for the rapid, inexpensive, quantitative, and convenient detection of SARS-CoV-2 biomarkers, methods of manufacturing, and methods of using the same, to identify a patient's prognosis and past/present SARS-CoV-2 infection status, wherein the biosensor comprises a microfluidics layer, a multimodal sensing layer comprising two or more working electrodes, and a logic circuit that may include a processor and non-transitory memory with computer executable instructions embedded thereon.

Multiplexed sensor for ultra-fast and low-cost COVID-19 diagnosis and monitoring

A portable biosensor for detecting and quantifying a target molecule in a biological sample and method of use include a biosensor fabricated with a recognition layer with an imprinted polymer, an electrode electrically coupled to the recognition layer, and a logic circuit that may include a processor and non-transitory memory with computer executable instructions embedded thereon, wherein the imprinted polymer is shaped to have a profile that substantially matches a profile of the target molecule, such that the target molecule can form-fit and bind to the imprinted polymer, thus changing an electrical property of the polymer layer that may be detected to identify the presence of the target molecule.
