Beschreibung
Zusammenfassung:	A device has a piezoelectric or ferroelectric substrate on which ice is deposited. Electrodes are connected to the substrate. A vector network analyzer is connected to the electrodes and configured to determine the resonant frequency of the substrate. An excitation module including a function generator communicates with the vector network analyzer and is connected to an amplifier. The amplifier is connected to the electrodes. The excitation module uses an automatic switch to apply to the electrodes an AC electrical signal having a frequency coinciding with the resonant frequency measured in the vector network analyzer and which changes gradually as the ice melts.
