SUMMARY:ESE Seminar: "(Re)building Human Dexterity: Inferring Musculoskeletal Dynamics for Next-Generation Assistive Devices & Diagnostics"
DESCRIPTION:While there exist a number of mechanically sophisticated exoskeletons\, prostheses\, and assistive robots\, with articulations similar to those of the intact human arm and hand\, these devices remain limited in their ability to augment human dexterity and safely interact with human users and collaborators. In particular\, due to the limits of conventional sensing\, robots remain locked in industrial cages\, prosthesis users can often modulate only a single degree of freedom\, and when human–device interactions do occur\, we have almost no understanding of the resulting physiological impacts on the user’s musculoskeletal system. \nIn this talk\, I will discuss my work addressing these dual problems of device capability and safety by leveraging two novel signal classes — muscle deformation\, as measured via ultrasound\, and vibration\, as measured via acoustic myography (AMG) — to probe individual muscle forces\, which cannot currently be measured noninvasively but are key to understanding musculoskeletal dynamics during dexterous motion. Specifically\, I will address our progress in precisely characterizing these signals and their relationship to muscle output force\, and in measuring them in real time\, paving the way for future research on the extraction of multiple independent signals for high-dimensional device control and enhanced overall understanding of the joint human–machine dynamical system\, both healthy and pathological.
