MEMS Strain Gauge on Steel: Test Fixture Design

Robert Azevedo
(Professor Albert P. Pisano)

The overall group project aims to produce a high-resolution MEMS strain gauge for applications on steel. This project aims to design and fabricate test rigs. The test rig design has three objectives: quantify accuracy and resolution of the MEMS strain gauges attached to steel bodies, provide comparison performance data to conventional foil strain gauges, and verify that these MEMS strain gauges will be able to accurately measure narrow-width strain events. A four-point bend test rig has been produced to satisfy the first two project aims. Further work will consist of testing specimens and integrating temperature control into the test rig.
