MEETING

Join us on May 11, 2022 via Zoom to review 2022 project milestones; network with faculty, students, and industry members; and learn about trending topics from leading experts.

Slide

Real-world applications of IoT often require flexibility, stretchability, and conformability to interface with the physical world. Flexible hybrid electronics integrates flexible substrates, novel materials, and printing methods with semiconductor ICs to create multi-functional integrated system technologies for a host of applications ranging from wearable devices to conformable interface electronics for smart everyday objects.

Slide
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.

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.

Focus Brief: Harsh Environment Sensing

The MIST Center has five strategic thrust areas; integration, power, wireless, computing and sensing. Within each thrust area, we have identified comprehensive research topics. One such topic is on Harsh Environment Sensing.

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. 

Since 2015, the MIST Center has funded $1.5M across 33 projects conducted by 13 faculty members resulting in 11 publications, 3 patents and 1 doctoral student hired by a member organization.
