About
Michael W. Shafer is a mechanical engineer and robotics researcher whose work sits at the dynamic intersection of soft robotics, biomimetic actuation, and smart materials. He is best known for pioneering research into artificial muscles—actuators designed to replicate the performance characteristics of biological muscle for use in robotics, prosthetics, and human-machine interaction. His 2021 introduction of "cavatappi" artificial muscles, fluid-driven actuators fabricated from inexpensive polymer tubes, garnered 88 citations and represented a significant leap forward in accessible, powerful compliant actuation. Complementing this, his widely cited comparative framework asking "What is an artificial muscle?" (77 citations) has become an important reference for researchers navigating the rapidly evolving soft robotics landscape. Earlier in his career, Shafer made foundational contributions to twisted polymer actuators (TPAs), developing experimental characterizations and predictive models that advanced understanding of these thermally driven smart materials. His work spans both theoretical modeling and experimental validation, reflecting a rigorous, application-driven approach. Beyond robotics, Shafer has explored unconventional domains such as solar energy harvesting from migrating elephant seals, demonstrating a creative breadth of engineering inquiry. His research collectively advances the goal of safe, effective human-robot integration.
