Researchers are confident that their levitation technology can beat the best gravimeters developed till date.
A research team led by Jason Twamley, a researcher in the theoretical physics of quantum science and technology at Japan’s Okinawa Institute of Science and Technology (OIST), has successfully demonstrated levitation without using any external energy source. The team developed a new material to achieve this feat, which has opened the doors to gravity-free technology in the future.
Objects made from superconductors or diamagnetic materials (those that can be repelled by a magnetic field) can float above magnets. This principle is also used in magnetic levitation, where superconducting magnets create a strong magnetic field and diamagnetic materials levitate, allowing objects to travel at high speeds, such as trains.
The technology can also be used to devise a range of advanced sensors for everyday use and to advance science. Twamley’s lab uses levitating materials to build oscillators, which can be used to develop ultra-sensitive sensors. Making these oscillators work without using external energy sources can make them easier to deploy, and this is what the research team at OIST set out to do. What they faced was a series of challenges.
