MEMS accelerometer: From engineering to medicine

The earliest accelerometer found its industrial applications in 1923 and could measure the acceleration and vibration of industrial components. Because it weighed about 1 lb and was extremely large in size, no engineer could foresee its utility in mobile electronic devices. The device used a resistance bridge along with electronic circuitry to measure the acceleration and vibrations of intended objects. In addition to its bulkiness, the accelerometer had lower resonant frequency, was fragile, and possessed low frequency response.
