The MIST Center has five strategic thrust areas; integration, power, wireless, computing and sensing. Within each thrust area, we have identified the following comprehensive research topics:
Harsh Environment Sensing
Example of Prof. Sheplak’s fully packaged optical MEMS 5HP.
While readily available commercial sensors may be adequate for consumer IoT and smart systems, smart systems for harsh environments involving one or more extremes of temperature, pressure, corrosive liquids, radiation, etc. often require specialized sensors.
Some target applications include aerospace, gas turbine, reactor, as well as seawater and in vivo applications.
RESEARCH
Realize an 18:1 return on investment by leveraging the total amount of research in the center.
RECRUITING
Discover rising stars with a vested interest in your organization’s success through mentorship and internships.
RELATIONSHIPS
Join with the right people, at the right time, at the right place. Our network is the recipe for success.
Thrust Areas
Our unique research portfolio comprises numerous technical experts in a breadth of technology fields ranging from novel materials and processing technologies to devices/transducers, packaging, and multi-physics modeling.
This diverse, complementary expertise together with strong experimental capabilities enables exploration for the breakthroughs in multi-functional integrated systems technologies. The pooled resources of the MIST Center enable a return on investment (ROI) that is much larger than the typical ROI for a single expert or single company contract.
