New microchip design harnesses sound waves on the surface for advanced sensing technologies
Posted by Saúl Morales Rodriguéz in category: computing
A team of researchers has for the first time successfully used lasers to generate guided sound waves on the surface of a microchip. These acoustic waves, akin to the surface waves produced during an earthquake, travel across the chip at frequencies nearly a billion times higher than those found in earth tremors.
By containing the sound wave on the surface of a chip, it can more easily interact with the environment, making it a perfect candidate for advanced sensing technologies.
The findings are published in APL Photonics.
