Abstract
A method and device for characterizing the response of resonant sensors. The method is based on an analytic algorithm that establishes a relationship between the complex admittance G of the sensor, measured at a single test frequency, the variations in resonance frequency and the losses, such as the quality factor at the acoustic resonator. The device includes at least one piezoelectric resonator on whose surface is deposited a thin layer of material, a fluid medium in contact therewith, a stable signal source, a frequency synthesis subsystem, a multiplex subsystem that enables the excitation/interrogation of a particular resonator, a signal conditioning and acquisition subsystem, a control subsystem based on the use of digital integrated circuits enabling the coordinated control of the different subsystems that make up the device.
