Progress in the development of highly reliable and sensitive diamond MEMS sensors. A NIMS-led research group succeeded in developing a high-quality diamond cantilever with among the highest quality (Q) factor values at room temperature ever achieved. The group also succeeded for the first time in the world in developing a single crystal diamond microelectromechanical systems (MEMS) sensor chip that can be actuated and sensed by electrical signals. These achievements may popularize research on diamond MEMS with significantly higher sensitivity and greater reliability than existing silicon MEMS.

MEMS sensors – in which microscopic cantilevers (projecting beams fixed at only one end) and electronic circuits are int...
