Development of high surface quality and large static displacement translating micromirror for MEMS FTIRS with application to alcohol interlock

This project is to develop a micromirror with large static translation displacement and high surface quality by combining two microfabrication processes. Based on the developed micromirror, the next generation alcohol interlock technology, i.e., MEMS (MicroElectroMechanial System) FTIRS alcohol interlock will be developed and commercialized in collaboration with ACS to overcome the limitations of the current technology to achieve much higher sensitivity and realize continuous monitoring of driver’s BAC, which is highly desired in the industry but cannot be realized with the current technology. This product will be added to ACS alcohol interlock product portfolio with much better performance than its existing products and its global competitors. Due to the high sensitivity and capability of continuous monitoring, the effectiveness and application of the automotive alcohol interlock can be significantly improved and expanded. With this new technology, the competitiveness and leadership of ACS in the automotive alcohol interlock industry will be greatly enhanced.
