Paper Abstract

The M beam device described herein is a surface mount accelerometer. This device is built from commonly available piezo material using a novel packaging approach that resolves many of the issues that make competing accelerometers expensive. The concept includes separating the piezo material into active and inactive areas by sawing the piezo material into an M shape. The two outer legs are used for package connection (inactive area) and the inner leg is free to move as a piezoelectric beam (active area). The design equations for M beam characteristics are presented.
