The Kentucky EPSCoR project, KAMPERS (Kentucky Advanced Manufacturing Partnership for Enhanced Robotics and Structures), aims to develop global excellence in next-generation flexible electronics, robotics, and manufacturing technologies. KAMPERS will advance the state-of-the-art in advanced manufacturing through integration of synthetic biology, 3D printing, and the emerging field of printed electronics to revolutionize the capabilities of robotic manufacturing infrastructure, medical assistive robots, prosthetics, and consumer products.
The KAMPERS team includes faculty, staff and students from eight universities and colleges across the state of Kentucky.
Our research team at the University of Louisville includes a group of 11 faculty from Electrical, Mechanical, Computer Science and Bio Engineering at Speed School, and two faculty from the Biology Department of the School Arts & Sciences. They are collaborating with colleagues at UK and several other regional universities including EKU, WKU and MoSu. Our team includes 11 Ph.D. students, 5 undergraduate researchers and 5(?) postdoctoral associates. In addition to the defined research thrust objectives enumerated below, we are also working to deploy robots to combat the spread of Covid-19 around medical facilities in the very near future and have been experimenting with incorporating UV and sprayers for disinfection.
Develop new sensing modalities designed to be integrated into structural robotic components, along with the multi-functional materials required to serve as electronic interconnects and insulators. This thrust develops the materials and fabrication processes needed to embed electronic function into structural components, and involves developing new materials, device configurations, and structural forms for demonstration of basic logic, sensing, and data processing arising from co-printed electronic and structural elements, along with on-board power generation and storage. Explore synthetic biology approaches to yield structural materials with programmable lifetimes, to reduce generation of persistent electronic waste.
