Collaboration partners
We collaborate with company partners on some of our federally funded research projects (e.g., Natl. Inst. Health, Dept. of Defense grants), as well as on independent projects initiated by the companies. All of our corporate partners contribute intellectually to the research. As progress is made, we provide to them detailed reports and plans for future research.
Lateral extension
Often, the technologies we develop have application in other fields outside of prosthetics. We aggresively pursue pilot projects with clinicians in a variety of disciplines to advance those efforts. We seek companies with sufficient capital to fund the research and bring those potential products to market. In exchange, companies receive a royalty-free license.
Companies sometimes seek expertise on projects they are conducting in house, and want to benefit from our many years of research experience. When maintaining corporate ownership of intellectual property is important, companies set up a consulting arrangement with Dr. Sanders through her outside firm, Nicholass LLC. Contact Dr. Sanders at
Test facilities
We operate a cost center in our lab (non-profit) to provide testing services for companies. Currently available test facilities are listed below:
Prosthetic sockets and models - shape quality
• Interface materials - mechanical characterization
• Prosthetic sock - thickness
