The microchip is capable of accurately measuring distances in materials, which could have applications in areas such as underwater measurement and medical imaging.
The new technology, which utilizes sound vibrations instead of light, could be useful for obtaining high-precision position measurements in materials that are opaque. This breakthrough could result in the development of new methods for monitoring the Earth’s climate and human health. The findings have been published in the journalThe microchip mainly consists of a thin ceramic sheet that is shaped like a trampoline.
This new technology could be used to measure positions in materials using sound waves. What makes it special is that it doesn’t need any precision hardware and is therefore easy to produce. “It only requires inserting a laser, and nothing else. There’s no need for complex feedback loops or for tuning certain parameters to get our tech to operate properly. This makes it a very simple and low-power technology, that is much easier to miniaturize on a microchip”, Norte says.

It's Pulitzer Prize day, honoring journalism's best workThe Pulitzer Prizes will be awarded Monday to honor outstanding journalism during a violent year that included Russia’s brutal invasion of Ukraine, mass shootings that targeted an elementary school and supermarket, and floods and flames fueled by climate change. The winners will be announced beginning at 3 p.m. Eastern time. The Pulitzers honor the best stories in journalism from 2022 in 15 categories, as well as eight arts categories focused on books, music and theater. The public service winner receives a gold medal. All other winners receive $15,000. The prizes were established in the will of newspaper publisher Joseph Pulitzer and first awarded in 1917.
