Ultrasound energy transfer systems can be an alternative for sensor-chargers aiming battery replacement avoidance and can be used in machine tool applications. An ultrasound input source can be used to send an acoustic signal through a machine. The signal is received by an ultrasound receiver based on piezoelectric component and should be converted into an electrical signal to supply or charge the sensor. Notwithstanding, for rotating machines, an air gap must be considered between the input source and the machine tool part. This paper deals with the acoustic-electrical energy transfer considering the changes in the propagation media of the ultrasound. Theoretical results are verified by means of an experimental setup.
