Powered exoskeletons allow users to perform limb motion with additional external power to increase the user\u2019s strength and endurance. This exoskeleton device combines active (actuated) and passive (spring-assisted) components to improve the performance of either component independently.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Additional information<\/h2>\n\n\n\n<section  \n    class=\"nau-block nau-block-panels   \" \n    data-layout_mobile=\"groupLayout-Stack gutter_Default panelLayoutPhotoTextVertical  photoAspect-1-1\"\n        data-layout_tablet=\"groupLayout-Stack gutter_Default panelLayoutPhotoTextVertical  photoAspect-1-1\"\n        data-layout_desktop=\"groupLayout-Tabs gutter_Default panelLayoutPhotoTextVertical  photoAspect-1-1\"\n        data-layout_xl=\"groupLayout-Tabs gutter_Default panelLayoutPhotoTextVertical  photoAspect-1-1\">\n\n    <div class=\"background-wrapper\">\n        <div class=\"block-main-content\">\n            \n            \n                            <div class=\"tab-nav\" role=\"tablist\" aria-label=\"Tabs for  articles\">\n                                                \n                        <button data-panel=\"panel--0\"\n                            role=\"tab\"\n                            aria-controls=\"panel--0\"\n                            class=\"active bg-true-blue bg-none\"\n                            tabindex=\"0\">Patent number and inventor<\/button>\n                                                \n                        <button data-panel=\"panel--1\"\n                            role=\"tab\"\n                            aria-controls=\"panel--1\"\n                            class=\"after-active bg-true-blue bg-none\"\n                            tabindex=\"-1\">Potential applications<\/button>\n                                                \n                        <button data-panel=\"panel--2\"\n                            role=\"tab\"\n                            aria-controls=\"panel--2\"\n                            class=\" bg-true-blue bg-none\"\n                            tabindex=\"-1\">Benefits and advantages<\/button>\n                                                \n                        <button data-panel=\"panel--3\"\n                            role=\"tab\"\n                            aria-controls=\"panel--3\"\n                            class=\" bg-true-blue bg-none\"\n                            tabindex=\"-1\">Case number and licensing status<\/button>\n                                    <\/div>\n            \n            \n            \n            <div class=\"panel-wrapper\">\n                \n                                \n                        <div class=\"panel bg-true-blue  panelTypeText  noHover \"\n                            data-role=\"tabpanel\"\n                            data-panel=\"panel--0\"\n                            id=\"panel--0\">\n\n                            \n                                                                    <div class=\"content\">\n                                            <div class=\"text-wrapper\">\n                                                                                                <h3 class=\"h3-tab-index\">Patent number and inventor<\/h3>\n                                                \n                                                                                                    <div class=\"text\">\n                                                        <p>Patent pending<\/p>\n<p>Zachary F.
