Abstract
A method for testing a drug delivery device including a piezoelectric transducer, a microcontroller, and a DC power source, with the piezoelectric transducer having an operative state and inoperative state. The method includes providing a drive signal to the piezoelectric transducer of the drug delivery device, determining an actuation voltage value or an actuation current value, and comparing the actuation voltage value or the actuation current value to a baseline value to determine whether the piezoelectric transducer is in the operative state or the inoperative state.
