Abstract:
1. A chemical sensor system comprising: a first cantilevered probe comprising: a driver circuit electrically coupled to the first and second electrodes and configured to actuate the cantilevered probe; a sensing circuit electrically coupled to the first and second electrodes and configured to sense oscillation of the cantilevered probe; a heater circuit electrically coupled to the resistive heater; and a plurality of additional cantilevered probes arranged in an array together with the first cantilevered probe, each of the plurality of additional cantilevered probes comprising: wherein the first cantilevered probe is actuated when, through the first and second electrodes, a drive voltage is applied to the piezoelectric layer by the driver circuit, the actuated cantilevered probe generating a displacement signal transmitted to the sensing circuit, and wherein the piezoelectric layers of each of the cantilevered probes of the array are connected in parallel.
