The approach to developing such a sensor has so far used a passive pillar-based design, with embedded piezoresistors in-substrate. The work started with sensor pillar dimensions of ~ 6 um diameter, 60 um height SU-8 pillars mounted on \u0027larger\u0027 2um x 2um (WxL) piezoresistors that demonstrated sensitivity to Fx of 0.012% per uN force. Since then, sensor pillar and piezoresistor geometries have been scaled to improve Fx sensitivity almost tenfold to 0.14% per uN with a noise-limited resolution of ~ 80 nN. Future goals of the proposed research are (1) improving Fx resolution to better than 10 nN; (2) demonstrating biocompatibility of the developed sensor by testing with real-life cell samples.\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Piezoresistive Micro-Pillar Force Sensors For Biological Cell Traction Force Sensing"}],"uid":"28475","created_gmt":"2023-12-21 16:11:49","changed_gmt":"2023-12-21 16:12:18","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2024-01-12T14:00:00-05:00","event_time_end":"2024-01-12T16:00:00-05:00","event_time_end_last":"2024-01-12T16:00:00-05:00","gmt_time_start":"2024-01-12 19:00:00","gmt_time_end":"2024-01-12 21:00:00","gmt_time_end_last":"2024-01-12 21:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Online","extras":[],"related_links":[{"url":"https:\/\/teams.microsoft.com\/l\/meetup-join\/19%3ameeting_YTRhMDBhM2UtZmRiYi00YmMxLWEzMGQtN2U2MDAxZTk1NTlh%40thread.v2\/0?context=%7b%22Tid%22%3a%22482198bb-ae7b-4b25-8b7a-6d7f32faa083%22%2c%22Oid%22%3a%227aec26ec-a216-4d71-8c79-ab7a9d410223%22%7d","title":"Microsoft Teams Meeting link"}],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"1808","name":"graduate students"},{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
