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.
