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