4.3.3 Acceleration Sensors

Accelerations inside nanoscale devices are often measured in the trillions of g's (g = 9.81 m/sec2). For example, an L = 1 nm diamondoid block (m = 3.5 x 10-24 kg) with thermal energy ~kT experiences random thermal accelerations of atherm ~ kT / g m L = 1011g's; a 10-nm logic rod with vibrational energy ~kT experiences ~1012 g oscillations; a 200-nm wide hoop spinning axially with 1000 m/sec rim speed has rotational acceleration of a ~ 1012 g's.
