A rapid bonding process for installing vacuum sealed MEMS strain sensor modules to mechanical components is being developed. This innovative process will be developed to replace conventional adhesive-based approaches. In particular, the silicon to steel bond must achieve these stringent requirements: long life, resistance to chemicals, short bonding process time, and a wide range of storage temperatures. To ensure that the strain within a steel substrate will be accurately measured by the MEMS strain gauge, properties of the bond layer between silicon and steel are observed and determined.
