MEMS and other Miniaturised Electronics as Geotechnical Engineering Tools
Dr Ryan D. Beemer
About the presentation
Microelectromechanical systems (MEMS) sensors have become a common part of everyday life. These sensors tell mobile phone screens to rotate when tilted, ensure the car icon in GPS applications points in the correct direction, and inform drivers when tyre pressures are low. The pervasiveness of MEMS is due to their low cost and high reliability which is achieved by using silicon mass production techniques like those employed for manufacturing computer processors. In recent years MEMS accelerometers have even found their way into geotechnical research and practice, mainly to measure tilt and soil mass deformation. However, MEMS accelerometers are just the tip of the silicon iceberg, there are still many different types of MEMS for geotechnical engineers to explore. This presentation will discuss a variety of MEMS (and other micro-electrical systems) sensors that have been developed for the mobile device, gaming, and automotive industries, and how they could be utilized in geotechnical engineering.
