Specializing in prosthetic limb systems at the CU Denver|Anschutz Medical Campus
The Weir Biomechatronics Development Laboratory strives to develop better prosthetic limb systems by conducting research in fields ranging from 3D metal printing to optogenetics. We believe that finding solutions requires pushing the bounds of technology and creativity every day. Our goal is to practically apply our knowledge to give back independence and confidence to people who use prosthetic limbs.
The Biomechatronics Development Lab designs and develops advanced upper-limb prosthetic components and their associated control interfaces. Our laboratory strives to build advanced robotic-artificial limb systems that accurately recreate the form and function of the human upper-limb lost due to amputation. Much of our research is focused on finding algorithms for the controllers of these limb systems. We have studies involving pattern recognition, muscle synergies, and real-time musculoskeletal models. We are always engineering new ways to relay a muscle's activity information to the prostheses controller. Currently we are using surface myoelectrode sensors (sEMG) and implantable myoelectric sensors (IMES) to decipher a person's motion intent. In addition, we are also developing optogenetic nerve cuffs to acquire more specific signals in the hopes of producing more accurate control systems.
