Rapid Screening of Physiological Changes Associated with COVID-19 Using Soft-Wearables and Structured Activities: A Pilot Study
Objective: Controlling the spread of the COVID-19 pandemic largely depends on scaling up the testing infrastructure for identifying infected individuals. Consumer-grade wearables may present a solution to detect the presence of infections in the population, but the current paradigm requires... Read more

Performance Evaluation of a Wearable Tattoo Electrode Suitable for High-Resolution Surface Electromyogram Recording
Commercial high-density surface electromyography (HDsEMG) electrodes have limited spatial fidelity, and require electrode paste. As a result, the recorded signals have limited sharpness, inadequate spatial density, and are prone to movement artifacts during muscle contraction. We here demonstrate a novel TATTOO electrode, a dry HDsEMG electrode with a programmable layout. The tattoo electrode is built on stretchable electronics and offers superior skin conformity that can guarantee recording of high-quality HDsEMG signal. We routinely record a larger signal amplitude with higher signal power and occupied bandwidth compared to commercial electrodes. This will potentially enable high-quality recording in clinical applications... Read more
