    "abstract": "The Casimir force between uncharged metallic surfaces originates from quantum\nmechanical zero point fluctuations of the electromagnetic field. We demonstrate\nthat this quantum electrodynamical effect has a profound influence on the\noscillatory behavior of microstructures when surfaces are in close proximity\n(\u003c= 100 nm). Frequency shifts, hysteretic behavior and bistability caused by\nthe Casimir force are observed in the frequency response of a periodically\ndriven micromachined torsional oscillator.",
