Realizing Field-Ready MEMS Gravimetry

We present the first field-deployable implementation of the MEMS Gravimeter Wee-g, designed for single-user operation, portability, and real-time monitoring. Trials confirm laboratory-grade performance, with bias instability as low as 3 µGal after 300 seconds of averaging, and sufficient sensitivity and stability to resolve gravity variations from Earth tides with high accuracy. While drift and environmental sensitivities remain areas for improvement, the results presented here outline a clear path toward practical, low-cost MEMS gravimetry for real-world applications.
