A multi-modal biosensor system includes a vibrating plate orientated along a plane. An actuator is interfaced with the vibrating plate and operable to vibrate the vibrating plate along the plane. The actuator includes two electrodes rigidly affixed to the vibrating plate. An optical support structure is rigidly affixed to the vibrating plate, and provides an outwardly facing surface to receive a measurement sample. A light source is configured to project light onto the outwardly facing surface of the optical support structure. A light detector is configured to capture light reflected from the outwardly facing surface of the optical support structure. A controller interfaces with the two electrodes and the light detector. The controller operates to detect changes in the vibrating motion of the vibrating plate concurrently with detecting changes in the light captured by the light detector.
