Could MEMS-based accelerometers be used for gravity surveys?

Michael S. Hons and Robert R. Stewart

ABSTRACT

Recently published results show promising developments in using MEMS-based accelerometers to record static gravity at microgravity-scale resolution. The challenge of adapting MEMS accelerometers from the seismic realm to the task and their potential to be a good platform for development are presented, and several advances are suggested to improve their very low frequency and static performance. An implementation is envisioned that would add a dedicated gravity-measurement chip to a seismic sensor, and provide microgravity data with minimal added cost in the field.
