HGN Lab Publishes Paper in MDPI Actuators

Torque-sensitive transmissions have emerged as promising solutions to meet this need by significantly increasing actuator efficiency and power density, but their modeling and analysis remain an open research topic. In this paper, we introduce the sensitivity between input displacement and output torque as a key metric to analyze the performance of these complex mechanisms in dynamic tasks. Our results show that sensitivity analysis is a valuable tool for designers to systematically analyze and create transmission systems capable of human-like physical behavior.

HGN Lab Publishes Paper in IEEE Transactions on Neural Systems and Rehabilitation Engineering (IEEE TNSRE)

In this study,  we show that varying the assistive knee torque provided by a powered knee prosthesis significantly improved weight-bearing symmetry, effort, and speed during the stand-up movement in eight above-knee amputees. Specifically, we observed improvements in the index of asymmetry of the vertical ground reaction force at the point approximating maximum vertical center of mass acceleration, the integral of the intact vastus medialis activation measured using electromyography, and the stand-up duration compared to the passive prosthesis. These results show that powered prostheses can improve functional mobility, potentially increasing quality of life for millions of people living with above-knee...

Dr. George Featured on Brown Journal of World Affairs Podcast

The Brown Journal of World Affairs is a semiannual international relations publication produced at Brown University’s Watson Institute for International and Public Affairs. Founded in 1993, the Journal provides a forum for world leaders, policymakers, and prominent academics to engage in a vigorous debate of intellectual breadth and vibrancy. Each issue examines salient and emerging international topics and is circulated widely in the United States and abroad. In recent years, contributors have included Jimmy Carter, Noam Chomsky, Dilma Rousseff, Joseph Nye, and many others. Dr. George’s podcast interview highlights his work on bionic prostheses, commercialization of new technology, and...
