Prognostic Integrated Multi-Sensor MEMS Module (PRISM)

Impact Technologies, in cooperation with the MicroElectronics Department at the Rochester Institute of Technology, are creating an ultra-small sensing system for measuring temperature, relative humidity and shock for use in prognostic applications. The long term II goal is to create a device that is smaller than a penny. This will enable collecting comprehensive usage data in areas where data collection was previously not possible. Of special note is measurement within critical electronic systems such as JCREW. The gated Phase II program is designed to show working sensor system size reductions - to very close to penny size, and ultimately to penny size at the end of Phase II. Key aspects of the Phase II effort include: - Integration of updated Phase I MEMS sensors with onboard embedded digital electronics to reach near-penny size(but slightly taller) showing the basic electronics design is appropriate. - Incorporating the 2nd and 3rd axes of shock and decreasing height of system to penny size by using aggressive electronics packaging concepts. In Phase II, penny-sized prototype sensors will be fabricated and parameter sensing will be verified. This provides the groundwork for application studies of near-commercial prototypes in follow-on Phase III field trials.
