In this work, the frost/ice formation on superhydrophobic/piezoelectric hybrid layer was investigated. The hybrid layer is prepared by depositing a superhydrophobic coating on a 1 mm thick piezoelectric PZT-4 ceramic sheet with diameter of about 47 mm. The contact angle of water drop on surface was 156°. The hybrid layer was actuated to vibrate by sinusoidal voltage waveform with amplitude of 200...
