Sound of Ice (SOI) is a scientific project whose objective is to develop a smart, energy-efficient, environmentally safe and autonomously operated de-icing procedure based on surface acoustic transducers integrated over large area substrates.

This will be achieved through the surface microengineering of systems capable of exciting plate and Rayleigh waves onto a variety of materials and that may incorporate anti-icing layers and SAW sensors, allowing operation according to predefined feedback algorithms.
