Abstract

Un método para probar un dispositivo de administración de fármacos que incluye un transductor piezoeléctrico, un microcontrolador, y una fuente de alimentación de DC, teniendo el transductor piezoeléctrico un estado operativo y estado inoperativo. El método incluye proporcionar una señal de accionamiento al transductor piezoeléctrico del dispositivo de administración de fármacos, determinar un valor de voltaje de accionamiento o un valor de corriente de accionamiento, y comparar el valor de voltaje de accionamiento o el valor de corriente de accionamiento con un valor de línea base para determinar si el transductor piezoeléctrico está en el estado operativo o en el estado inoperativo.
