Our Mission

Our research focuses on advancing and translating clinically relevant solutions for upper limb prostheses. Through strategic partnerships with the VA, NIH, CU Denver-Anschutz, CU Boulder, Point Designs, and other institutions, we strive to create a better future for prosthesis users through four main areas of endeavor: Human Interfaces, Algorithm Development, Prosthetic Components, and Sensory Feedback.

What We Do

Our work encompasses novel technologies such as surface electromyography, machine learning, optogenetics, and blood-based fuel cells. We explore innovative approaches using 3D printing to design customized prostheses, develop advanced control algorithms to enhance both body-powered and externally-powered prostheses, and investigate optogenetics for interfacing with the peripheral nervous system to achieve organ modulation, brain circuit control, and muscle activation for prosthesis control and sensory feedback restoration.
