For the first time, physicists at Delft University of Technology in the Netherlands have combined two Nobel Prize-winning technologies to create a new technology on a microchip. Related papers were recently published in Nature Communications. China Manufacturer of stainless steel medical equipment
The microchip can measure distances in materials with high precision. Since the technique uses sound vibrations instead of light, it can be adapted for high-precision position measurement in opaque materials. This could lead to new technologies for monitoring Earth’s climate and human health.
The microchip consists essentially of a thin piece of ceramic shaped like a trampoline. The “trampoline” has holes to enhance interaction with the laser light and is one-thousandth the diameter of a human hair.
The researchers found that if ordinary laser beams were aimed at these “trampolines,” their surfaces would vibrate violently.
By measuring the laser light reflected from the vibrating surface, the team noticed a comb-like vibrational pattern that they hadn’t seen before. Scientists realized that the comb-like features of the “trampoline” could serve as a ruler for precisely measuring distances.
The new technology can use sound waves to measure the position of a material. Its special feature is that it does not require any sophisticated hardware, so it is easy to produce. China Manufacturer of stainless steel medical equipment
“Just plugging in a laser doesn’t require anything else — complex feedback loops or adjusting certain parameters. This makes it a very simple and low-power technology that’s easier to miniaturize on a microchip.” Richard Norte, corresponding author of the paper, said, “Once it is realized, we can put these microchip sensors anywhere because they are small in size.”
The new technique is based on two unrelated Nobel Prize-winning technologies, optical tweezers and frequency combs. “These two concepts are often related to light, but don’t really overlap in any way. We’ve uniquely combined them to create an easy-to-use microchip technology based on sound waves. This ease of use may be beneficial to people.” How you measure the world around you has a big impact,” Norte said. China Manufacturer of stainless steel medical equipment
When the researchers aimed the laser beam at the tiny “trampoline,” they realized that the force the laser exerted on the “trampoline” produced overtone vibrations in the “trampoline” membrane.
“These forces are called optical tweezers because they use light to trap particles in a single point,” Norte explained. “This technology, which won a Nobel Prize in 2018, allows us to manipulate the smallest particles with extreme precision.”
“While optical frequency combs won the Nobel Prize in 2005, they are used in laboratories around the world for very precise time measurements and distance measurements,” Norte said. sound vibrations instead of light. Acoustic frequency combs travel better than light waves through opaque materials.” China Manufacturer of stainless steel medical equipment
