Abstract: Disclosed are various embodiments for integrated diffuse correlation spectroscopy. A first control signal can be sent to a switch to cause an integrator to integrate a current from a photodiode. An integrated current can be received from the integrator, and a data signal can be sent to a computing device based at least in part on the integrated current. A second control signal can be sent to a switch to cause the integrator to cease integrating the current from the photodiode.

Abstract: The present disclosure presents glucose sensing methods and systems. One such system comprises an electrospun-nanofibrous-membrane (ENFM)-based amperometric glucose sensor integrated on a silicon chip, in which the glucose sensor has a working electrode, a reference electrode, and a counter electrode, wherein the working electrode comprises an ENFM-based sensing electrode. The system further comprises a potentiostat circuit integrated on the silicon chip such that the potentiostat circuit comprises a voltage control unit to control a voltage difference between the working electrode and the reference electrode and a transimpedance amplifier to measure a current flow between the working electrode and the counter electrode, in which a strength of the current flow corresponds to an amount of glucose present in a sample of blood on the glucose sensor.

Abstract: A breath collection device can detect changes associated with pathogenesis of a disease, such as COVID-19, including biomarkers of immune response for respiratory symptoms, central nervous system injury, and/or peripheral nervous system injury in user breath and/or odor. The breath collection device can detect concentrations of alcohol, acetone, and carbon monoxide in user breath samples. A breath sample can be received in an internal bladder of the device for sensor analysis. Concentrations of alcohol, acetone, and carbon monoxide can be determined by calibrated calculation. A detection method for alcohol, acetone, and carbon monoxide can provide a non-invasive, rapid, and selective detection of gases in a variety of applications in virus detection as well as agricultural and homeland security.
