A piezoelectric analytical sensor system is provided that includes a piezoelectric crystal having a sensing surface. The piezoelectric crystal is driven at a base oscillation frequency that is responsive to an analyte interacting with the sensing surface of the crystal. A crystal resonator in mechanical communication with the crystal drives the crystal at the base oscillation frequency. An electronic circuit is provided for measuring a vibrational frequency of the crystal and relating the vibrational frequency to a quantity of the analyte in contact with the sensing surface of the piezoelectric crystal. A modular interface in electrical communication with the electronic circuit is provided to engage an electronic device and derive power from that electronic device.
