Abstract
A method for determining the state of at least one sensor, the method using a first electromechanical transducer and a second electromechanical transducer that are coupled to a substrate, and a non-linear electrical circuit connected between the second electromechanical transducer and the sensor, the method comprising the steps of: applying an electrical signal at a first amplitude to the terminals of the first electromechanical transducer, and determining a first set of values of a parameter characteristic of the electrical impedance of the first electromechanical transducer in response to the application of the electrical signal; applying the electrical signal at a second amplitude to the terminals of the first electromechanical transducer, and determining a second set of values of the parameter characteristic of the impedance; measuring a difference between the first set of values and the second set of values; determining a state of the sensor on the basis of the difference between the first set of values and the second set of values.
