报告摘要：
人体是一个丰富的能源。对于越来越复杂的便携式设备的供能问题，利用生物力学的能量采集（在日常活动中的人体发电）是一项颇具前景的电池替代方案。有效地采集行走中的能量需要了解行走中的生物力学和生理学原理，以及机电工程的创新。
演讲的第一部分，将会论述两种能量采集设备：膝上能量采集器和能量采集背包。内容包括行走中的生物力学、机械系统的设计、人体实验结果。
第二部分，将简要介绍基于惯性/磁性传感器的步态参数的估计方法。
Qingguo Li教授的个人简历：
李教授在西北工业大学获学士学位和硕士学位，2006年在加拿大西蒙菲莎大学获机器人学工程博士学位。他的博士研究成果被授予Governor General's Gold Medal，是加拿大为研究生授予的最有声望的奖励。毕业后，李教授在西蒙菲莎大学从事有关人体运动学的博士后研究工作。他所研究的膝上能量采集器已在《科学》杂志上发表文章，并产生了重要影响。李教授拥有4个美国专利，而且其膝上能量采集器被《时代周刊》评为2008年度最重要的50个发明之一。李教授参与共同创立了一家能量采集研发公司，Bionic Power Inc（仿生电力公司）。李教授于2009年加入加拿大女王大学机械与材料工程学系，现已成为一名副教授（终身教职）。他最近发明的能量采集背包已授权给加拿大另一家公司。他的最新研究涉及行走辅助机器装置的能量采集与节能关键技术，以及用于人体运动分析的穿戴式传感器技术。
Energy Harvesting During Human Walking:
Biomechanics and Device Design
Dr. Qingguo Li
Dept. of Mechanical and Materials Engineering
Queen's University, Kingston ON, Canada
Humans are a rich source of energy. Biomechanical energy harvesting—generating electricity from people during daily activities—is a promising alternative to batteries for powering increasingly sophisticated portable devices. Effectively harvesting energy from walking requires understanding of walking biomechanics and physiology as well as engineering innovations. In the first part of the talk, I will discuss the development of two energy harvesting devices: a knee-mounted energy harvester and an energy harvesting backpack. It will include human walking biomechanics, mechanical system design, human experimental results.
In the second part of the talk, I will briefly discuss our recent development on inertial/magnetic sensor-based gait parameter estimation methods.
Brief Bio. of Dr. Qingguo Li
Dr. Li earned Bachelors and Master Degree from Northwestern Polytechnical University (Xi'an, China), and Ph.D. in Engineering (robotics) from Simon Fraser University (SFU), Canada, 2006. His doctoral work was awarded the Governor General's Gold Medal, the most prestigious award for graduate students in Canada. After graduation, Dr. Li did his postdoctoral work at the school of Kinesiology at SFU. His postdoctoral work on knee-mounted energy harvester has been featured as a peer-reviewed article in the journal of Science . Dr. Li was an inventor of four US patents and the invention on energy harvester has been selected as one of the 50 most important inventions of the year 2008 by the Time magazine. Dr. Li is a co-founder of an energy harvesting R&D company, Bionic Power Inc. Dr. Li joined Queen's Mechanical and Material Engineering Department in 2009 and currently is an associated professor. His newly invented energy harvesting backpack has enabled another company in Canada. His current research includes developing energy efficient robotic devices for walking assistance and energy harvesting, as well as wearable sensor technology for human movement analysis.
