ABSTRACT
This paper reports dynamic behavior of a liquid-state accelerometer prototype, which uses a liquid marble as the inertial proof mass. The governing equation is developed in comparison with the solid-state proof mass in a conventional accelerometer. Numerical analysis and experimental validation show that with appropriate parameters, resonance frequency of the sensor can be designed below 10 Hz, which falls into the range of low frequency body motion. The work provides the basis for development of a new paradigm of motion sensing with reduced fabrication and assembly complexity, which is promising for next generation accelerometers for low frequency motion detection.
