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, where mechanical devices are manufactured by successive deposition of thin layers of silicon. Such micro-resonators are used to make tiny vibration sensors. Only the comb-like detector end of the micro-resonator is seen here, the thin strand of silicon running out of frame in the top left is attatched to a large resonant mass. To give an idea of scale, the silicon strand is 2 microns thick and 2 microns wide.
