Researchers at Tohoku University have successfully integrated nitrogen-vacancy centers directly into micro-electromechanical systems (MEMS) to dynamically measure bending stress and vibrations. This fabrication method embeds the quantum sensor within the device itself rather than attaching it externally, enabling real-time monitoring of changing stress states in microscopic structures. The advancement demonstrates a practical application of diamond defect physics for high-precision sensing in mechanical engineering contexts.

Researchers at Tohoku University integrated a quantum sensor directly into micro-electromechanical systems, or MEMS, to detect bending stress.
©Yuta Ochiai et al · tohoku.ac.jp Tohoku University researchers are using a flaw in diamond to precisely measure stress within microscopic devices. The team intentionally created nitrogen vacancy centers, defects in a diamond crystal lattice, and integrated them directly into a micro-electromechanical system (MEMS) cantilever. This approach utilizes optically detected magnetic resonance, a technique sensitive to both magnetic fields and mechanical stress, to track…
