Abstract:
1. A sensor for sensing properties of an electrode-degrading analyte, comprising: a lateral field excitation quartz crystal microbalance (QCM) resonator having a crystal substrate, wherein the QCM resonator is supported by a housing; the crystal substrate of the QCM resonator comprises an analyte contact surface on a first side and an electrode depositing surface on a second side; said housing having a base and an analyte support container; a plurality of electrodes connected to said electrode depositing surface and are laterally spaced apart from another, wherein the electrodes are only connected to the electrode depositing surface; said QCM resonator propagates a bulk acoustic wave and generates an electric field; said analyte contact surface of said crystal substrate is on the opposite side of the electrode depositing surface and said electrodes, and confines said electrode-degrading analyte to said analyte contact surface without contacting said electrode depositing surface and said electrodes in order to test said electrode-degrading analyte without damaging said electrodes and said sensor; and a seal interposed between said QCM resonator and said analyte support container.
