innovation for industry
Ultrasonic waves generated by an array of piezoelectric transducers could potentially remove water droplets, grease, and grime from transparent surfaces. Leti and Silicon Valley startup Innovasonic are exploring the technology's potential.
Fighter plane windshields already benefit from ultrasonic-wave cleaning systems. The systems are effective, but not very discreet: The piezoelectric transducers are contained in bulky ceramic housings. "We want to come up with a system that is invisible to the naked eye," said CEA-Leti Program Director Jean-Philippe Polizzi. "Windshields, PV solar panels, and automotive camera lenses are just a few of the many transparent surfaces that must be perfectly clean at all times."
