Potential applications for these diminutive devices span an array of fields, including healthcare, exploration, environmental monitoring, search and rescue, industrial maintenance, and digital agriculture. However, the design of microrobotics systems is inherently tied to scaling-law constraints; as length scales decrease, surface forces and viscous forces (among others) begin to dominate inertial forces. This leads to fabrication bottlenecks, struggles with energy\/power autonomy, and the need for specialized and often unconventional actuators. \r\n\r\nIn this talk, I will present three unconventional microactuators developed in my own group. Each leverages distinct physical principles to achieve high forces, frequencies, power densities, and integration potential in microrobotic platforms. These innovations highlight both the limitations imposed by microscale regimes and the opportunities that emerge when we embrace nontraditional transduction mechanisms for locomotion and manipulation.", "occurrence_notes":"https:\/\/umich.zoom.us\/j\/98302088175", "guid":"140186-21886714@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/140186", "building_id":"1000406", "building_name":"Lurie Biomedical Engineering (formerly ATL)", "campus_maps_id":"7", "room":"1130", "location_name":"Lurie Biomedical Engineering (formerly ATL)", "has_livestream":0, "cost":"", "tags":["seminar","Basic Science","Biointerfaces","biomedical","biomedical engineering","Bioninterfaces","Biosciences","Biotechnology","bme","engineer","engineering","Medicine","Michigan Engineering"], "website":"http:\/\/bme.umich.edu", "sponsors":[ { "group_name":"Biomedical Engineering", "group_id":"1143", "website":"https:\/\/www.facebook.com\/profile.php?id=100094127215673" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_2x\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/10\/event_140186_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/10\/event_140186_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21886714 } , "138900-21884217": { "datetime_modified":"20250926T160236", "datetime_start":"20251009T153000", "datetime_end":"20251009T163000", "has_end_time":1, "date_start":"2025-10-09", "date_end":"2025-10-09", "time_start":"15:30:00", "time_end":"16:30:00", "time_zone":"America\/Detroit", "event_title":"IES Energy Seminar Series - From Retirement to Reuse: Unlocking the Full Potential of EV Batteries in Stationary Storage", "occurrence_title":"", "combined_title":"IES Energy Seminar Series - From Retirement to Reuse: Unlocking the Full Potential of EV Batteries in Stationary Storage: Ziyou Song, University of Michigan, Electrical and Computer Engineering", "event_subtitle":"Ziyou Song, University of Michigan, Electrical and Computer Engineering", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Abstract: \r\nMillions of electric vehicle (EV) batteries are projected to retire over the next decade, often retaining substantial capacity left. Repurposing these batteries offers a promising solution to address challenges in the battery industry, including raw material scarcity, supply chain constraints, and the need for a circular economy. However, current EV batteries mainly retire after their performance becomes unsatisfactory, leading to heterogeneous health conditions that diversify lifetime during second use. There is a clear need for guidance on reuse strategies to maximize their whole-lifecycle value, including reuse in lower-demand applications. Here, we assess over 101,000 active retirement-reuse-retirement scenarios for EV batteries across popular stationary energy storage applications. The whole-lifecycle value of EV batteries is quantified using real-world data from EV batteries and their digital twins. For EV batteries retired at different mileages, we simulated their remaining useful life under realistic second-use applications. The tradeoff between first-life benefits and second-lifetime benefits is analyzed, and recommendations for selecting second-use applications based on first-life usage conditions are investigated. Our results demonstrate the feasibility of repurposing retired EV batteries and underscore the importance of whole-lifecycle management to enhance circular economy.\r\n\r\nBiography:\r\nZiyou Song is an Assistant Professor in the Department of Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor.
