Gravimeters are used for measuring the local gravitational acceleration. The use of current commercially available gravimeters, however, has been limited by their high cost and large size. In this study, a microelectromechanical system (MEMS) based relative gravimeter with an acceleration sensitivity of 8 μGall / √ (Hz) is demonstrated. The MEMS gravimeter, along with the custom interface electronics, is embedded on a battery powered portable platform. The portable platform enables continuous recording of the sensor response, while simultaneously measuring critical temperature and tilt parameters. To demonstrate the long-term stability of the system, the reported MEMS gravimeter platform was used to detect the Earth tides. In this paper, the first results from these measurements have been discussed.
