1. An analyte monitor comprising:
a light emitter to emit light toward a target;
a sensor to sense acoustic waves generated by analyte molecules in the target in response to the light emitted by the light emitter;
a cathode and an anode configured to come in contact with the target, wherein an area on the target on which the light emitted by the light emitter is incident is closer to the cathode than to the anode;
a voltage controller coupled to the cathode and the anode to bias the cathode and the anode; and
a signal processor configured to estimate a concentration level of an analyte based on the acoustic waves sensed by the sensor.
