Tasks often taken for granted by the able-bodied \u2014 buttoning a shirt, picking up a telephone, using cooking and eating utensils \u2014 become frustrating, nearly impossible feats due to reduced gripping strength and motor control.<\/p>\n\r\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/wlKDBUToPzc?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span>\n<\/div>\n<figcaption class=\"wp-element-caption\"> <\/figcaption><\/figure>\n\n\r\n\n<p>The stage is now set for that to change, however, thanks to Walsh\u2019s expertise in soft, wearable robotic systems and a development approach that involves the glove\u2019s potential end users in every step of testing and development. The holistic approach ensures that technology development goes beyond simple functionality to incorporate social and psychological elements of design that promote seamless adoption by its end users.<\/p>\n<p>\u201cFrom the start of this project, we\u2019ve focused on understanding the real-world challenges facing these patients by visiting them in their homes to perform research,\u201d said Walsh, an assistant professor of mechanical and biomedical engineering and founder of the <a href=\"http:\/\/biodesign.seas.harvard.edu\/\">Harvard Biodesign Lab<\/a> at SEAS, and a core faculty member at the Wyss Institute. A team of undergraduate students contributed to an early glove design as part of his ES227: <a href=\"http:\/\/mdi.seas.harvard.edu\/es227\">Medical Device Design course<\/a>.<\/p>\n<p>Wyss Technology Development Fellow Panagiotis Polygerinos and Kevin Galloway, a mechanical engineer at the institute, incorporated patient feedback at every stage of development in an effort to maximize the glove\u2019s potential for translation.<\/p>\n<p>\u201cUltimately, patients have to be comfortable with wearing the glove,\u201d said Galloway. \u201cIn addition to glove function, we found that people cared about its appearance, which could have a big impact on whether or not the glove would be a welcome part of their daily routine.\u201d<\/p>\n<p>Walsh\u2019s team adapted the mechanics to make the glove feel more comfortable and natural to wearers. Over several iterations of design, the actuators powering movements were made smaller and were modified to distribute force more evenly over the wearer\u2019s fingers and thumb. The resulting soft, <a href=\"http:\/\/softroboticstoolkit.com\/actuators\">multisegment actuators<\/a>, which are composite tubular constructions of Kevlar fibers and silicone elastomer, support <a href=\"http:\/\/softroboticstoolkit.com\/book\/fr-variation-motion\">the range of motions<\/a> performed by <a href=\"http:\/\/softroboticstoolkit.com\/book\/case-study-soft-wearable-device-thumb-rehabilitation\">human fingers<\/a>. The glove\u2019s control system is portable and lightweight and can be worn using a waist belt or attached to a wheelchair.<\/p>\n<p>Now, the team is working to improve control strategies that will allow the system to detect the wearer\u2019s intent. One potential solution is to leverage surface electromyography using small electrical sensors in a cuff worn around the forearm. The electromyography sensors detect residual muscle signals fired by motor neurons when the patient attempts a grasping motion and could be used to directly control the glove.<\/p>\n<p>\u201cWe are continuing to test the design of the soft robotic glove on patients, in relation to making it customizable for the specific pathologies of each individual and understanding what control strategies work best \u2014 but we\u2019re already seeing a lot of exciting proof-of-concept experimental results,\u201d said Walsh. \u201cThe current goal is to refine the overall system sufficiently so we can begin a feasibility trial with multiple patients later this year.\u201d<\/p>\n<p>Walsh and his team have been helped in their work by George Whitesides, Harvard\u2019s Woodford L. and Ann A. Flowers University Professor, and SEAS\u2019s <a href=\"http:\/\/www.seas.harvard.edu\/directory\/rjwood\">Robert Wood<\/a>, Charles River Professor of Engineering and Applied Sciences, who are also Wyss core faculty members.<\/p>\n<p>The design of the glove has been published in the journal <a href=\"http:\/\/www.sciencedirect.com\/science\/article\/pii\/S0921889014001729\">Robotics and Autonomous Systems<\/a> and the team also recently presented it at the International Conference on Robotics and Automation. In August, the team\u2019s electromyography control work will be presented at the International Conference on Robotics Research in Singapore.<\/p>\n<p>Down the road, the team is interested in developing the glove into a rehabilitation tool for various hand pathologies, and in extending the glove\u2019s assistive functions beyond the joints in the hand toward the development of soft robotic systems that aid impaired elbow and shoulder movements, as well.<\/p>\n\n\n\n<\/div>\n\n\t\t","protected":false},"excerpt":{"rendered":"<p>Having achieved promising results in proof-of-concept prototyping and experimental testing, a soft robotic glove under development by Conor Walsh and a team of engineers at the Harvard John A.

The holistic approach ensures that technology development goes beyond simple functionality to incorporate social and psychological elements of design that promote seamless adoption by its end users.<\/p>\n<p>\u201cFrom the start of this project, we\u2019ve focused on understanding the real-world challenges facing these patients by visiting them in their homes to perform research,\u201d said Walsh, an assistant professor of mechanical and biomedical engineering and founder of the <a href=\"http:\/\/biodesign.seas.harvard.edu\/\">Harvard Biodesign Lab<\/a> at SEAS, and a core faculty member at the Wyss Institute. A team of undergraduate students contributed to an early glove design as part of his ES227: <a href=\"http:\/\/mdi.seas.harvard.edu\/es227\">Medical Device Design course<\/a>.<\/p>\n<p>Wyss Technology Development Fellow Panagiotis Polygerinos and Kevin Galloway, a mechanical engineer at the institute, incorporated patient feedback at every stage of development in an effort to maximize the glove\u2019s potential for translation.<\/p>\n<p>\u201cUltimately, patients have to be comfortable with wearing the glove,\u201d said Galloway. \u201cIn addition to glove function, we found that people cared about its appearance, which could have a big impact on whether or not the glove would be a welcome part of their daily routine.\u201d<\/p>\n<p>Walsh\u2019s team adapted the mechanics to make the glove feel more comfortable and natural to wearers. Over several iterations of design, the actuators powering movements were made smaller and were modified to distribute force more evenly over the wearer\u2019s fingers and thumb. The resulting soft, <a href=\"http:\/\/softroboticstoolkit.com\/actuators\">multisegment actuators<\/a>, which are composite tubular constructions of Kevlar fibers and silicone elastomer, support <a href=\"http:\/\/softroboticstoolkit.com\/book\/fr-variation-motion\">the range of motions<\/a> performed by <a href=\"http:\/\/softroboticstoolkit.com\/book\/case-study-soft-wearable-device-thumb-rehabilitation\">human fingers<\/a>. The glove\u2019s control system is portable and lightweight and can be worn using a waist belt or attached to a wheelchair.<\/p>\n<p>Now, the team is working to improve control strategies that will allow the system to detect the wearer\u2019s intent. One potential solution is to leverage surface electromyography using small electrical sensors in a cuff worn around the forearm. The electromyography sensors detect residual muscle signals fired by motor neurons when the patient attempts a grasping motion and could be used to directly control the glove.<\/p>\n<p>\u201cWe are continuing to test the design of the soft robotic glove on patients, in relation to making it customizable for the specific pathologies of each individual and understanding what control strategies work best \u2014 but we\u2019re already seeing a lot of exciting proof-of-concept experimental results,\u201d said Walsh. \u201cThe current goal is to refine the overall system sufficiently so we can begin a feasibility trial with multiple patients later this year.\u201d<\/p>\n<p>Walsh and his team have been helped in their work by George Whitesides, Harvard\u2019s Woodford L. and Ann A. Flowers University Professor, and SEAS\u2019s <a href=\"http:\/\/www.seas.harvard.edu\/directory\/rjwood\">Robert Wood<\/a>, Charles River Professor of Engineering and Applied Sciences, who are also Wyss core faculty members.<\/p>\n<p>The design of the glove has been published in the journal <a href=\"http:\/\/www.sciencedirect.com\/science\/article\/pii\/S0921889014001729\">Robotics and Autonomous Systems<\/a> and the team also recently presented it at the International Conference on Robotics and Automation. In August, the team\u2019s electromyography control work will be presented at the International Conference on Robotics Research in Singapore.<\/p>\n<p>Down the road, the team is interested in developing the glove into a rehabilitation tool for various hand pathologies, and in extending the glove\u2019s assistive functions beyond the joints in the hand toward the development of soft robotic systems that aid impaired elbow and shoulder movements, as well.<\/p>\n\n\n\n<\/div>\n"}},"jetpack-related-posts":[{"id":172528,"url":"https:\/\/news.harvard.edu\/gazette\/story\/2015\/07\/robotic-insect-mimics-natures-extreme-moves\/","url_meta":{"origin":171483,"position":0},"title":"Robotic insect mimics nature\u2019s extreme moves","author":"harvardgazette","date":"July 31, 2015","format":false,"excerpt":"A team of researchers from Harvard and Seoul National University has unveiled a novel robotic insect that can jump off the surface of water.
