Geotechnical instrumentation using Micro-Electro-Mechanical Systems (MEMS) are relative newcomers to this conservative industry. This article aims to describe a new MEMS-based system for in situ deformation and vibration monitoring. After an introduction to the design and methodology of this system, some of the questions surrounding the use of MEMS sensors will be addressed, including temperature sensitivity, long-term stability and relative cost. Methods of installation and retrieval will also be briefly described. Finally, a description and validation of recorded field data from an instrumented unstable slope in California will be presented.
