Abstract: Systems and methods are described herein for utilizing a photoacoustic sensor for estimating analyte concentration levels. Also described here are training methods for training an analyte sensor to more accurately estimate an analyte concentration level on the basis of a received acoustic signal.

Abstract: An example method for calibrating a glucose sensor includes determining, by one or more processors, a set of electrical parameters for the glucose sensor of a plurality of glucose sensors and determining, by the one or more processors, a cluster for the glucose sensor based on the set of electrical parameters. Each cluster of the plurality of clusters identifies respective configuration information. In this example, the method includes configuring, by the one or more processors, the glucose sensor to determine a glucose level of a patient based on configuration information identified by the determined cluster.

Abstract: The disclosed techniques involve a light emitter configured to emit light toward the skin of a person, a light emitter controller configured to control the light emitter to emit the light in pulses having a pulse duration and at a pulse repetition frequency, a resonance chamber positioned to receive acoustic waves generated in the person in response to the light emitted by the light emitter, a sensor configured to sense acoustic waves in the resonance chamber, and a signal processor configured to estimate a glucose concentration level in the person based on the acoustic waves sensed by the sensor. The resonance chamber is sized to form a standing wave that has an acoustic wavelength of interest when glucose analytes are present in the region of the skin of the person. The pulse duration and the pulse repetition frequency of the emitted light are set at values that support the standing wave having the acoustic wavelength of interest.
