title = "Sub-g Bistable Frequency Sensor with a Tunable Threshold",
abstract = "We report on a bistable electromechanical device with an electrostatically adjustable acceleration threshold allowing real-time, wide-band measurement of a vibrating host structure frequency. The operational principle of the inertial switch-type sensor is based on the level crossing approach. By monitoring the time intervals between the pull-in events resulting in an ohmic contact between the electrodes the signal frequencies in the range between 15 Hz and up to 900 Hz were measured using the device with a natural frequency of 900 Hz. Operation in the vicinity of the critical pull-in point allowed frequency measurements of a signal with sub-g accelerations. Since the device combines both sensing and signal-processing functions, the post-processing of the output, which is wirelessly transmitted to a cell phone, is reduced to minimum. The suggested sensing principle can be implemented in structural health monitoring networks and wearable biomedical devices.",
