Micro Technology: Micromechanics: Scanning electron micrograph (SEM) of a mite (Acarimetaseiulus occidentalis) on the surface of a silicon micro-resonator 'chip'. The micro- resonator, or 'semaphore structure', is a product of micromechanics. Micro-resonators are use to make tiny vibration sensors for engineering use. The comb-like detector ends of the micro- resonators are seen here, a thin strand of silicon running from the left detector toward top left is attached to a large resonant mass. The absence of a resonant mass fixed to the right detector indicates a fault in manufacture. To give an idea of scale, the silicon strand is 2 microns thick and 2 microns wide.
