Researchers at the A*STAR Quantum Innovation Center (A*STAR Q.InC), part of the Research, Innovation and Enterprise (RIE) Flagship in Semiconductors, have developed a levitated, millimeter-scale rotor that continued spinning for more than 10 hours after its drive was switched off, achieving the lowest energy loss reported for a mechanical rotor of its size.
Levitated spinning device could help navigation when GPS is unavailable
