However, developing energy storage and signal transduction devices that can operate reliably under mechanical deformation remains challenging. Conventional liquid electrolytes are widely used in these devices but face problems such as leakage, evaporation, and poor mechanical stability under strain. To overcome these issues, hydrogel electrolytes emerge as a robust alternative by combining high ionic conductivity with intrinsic mechanical flexibility. Furthermore, their properties can be precisely tuned to meet the divergent needs of distinct electrochemical devices. This proposal focuses on engineering a versatile hydrogel electrolyte platform for stretchable batteries and organic electrochemical transistors (OECTs). To this end, the first research thrust develops stretchable aqueous lithium-ion batteries using dual-salt hydrogel electrolytes. The polymer network and salt composition are rationally designed to achieve a wide electrochemical stability window, high ionic conductivity, stretchability, and self-healing. These electrolytes are integrated with stretchable electrode architectures to maintain stable battery performance during mechanical deformation and after damage. The second thrust applies this hydrogel platform to OECTs, which impose distinct requirements for ionic transport and electrochemical operation. This work systematically examines how electrolyte composition and physiochemical properties affect transistor performance, operating potential, and long-term cycling stability. It also investigates the impact of humidity, temperature, and environmental hydration on device operation. The optimized hydrogels are then integrated into stretchable OECTs to evaluate their electrochemical performance under applied mechanical strain. Through these two applications, this research establishes fundamental design principles for hydrogel electrolytes and supports the development of fully stretchable electronic systems with seamlessly integrated energy storage and signal transduction.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E\u003C\/p\u003E\u003Cul\u003E\u003Cli data-list-item-id=\u0022e0983bae0adb4603c0c9600e857f2e411\u0022\u003EProf. Anju Toor \u2013 School of Materials Science and Engineering (advisor)\u003C\/li\u003E\u003Cli data-list-item-id=\u0022ebb01971314b96d5bed033044062cb91c\u0022\u003EProf. Antonio Facchetti \u2013 School of Materials Science and Engineering\u003C\/li\u003E\u003Cli data-list-item-id=\u0022e5b355f5a241cf089dc0d3992dc2b90ed\u0022\u003EProf. Matthew McDowell \u2013 School of Materials Science and Engineering\u003C\/li\u003E\u003Cli data-list-item-id=\u0022ebceec6afaf93a561e9b653859069e311\u0022\u003EProf. Seung Soon Jang \u2013 School of Materials Science and Engineering\u003C\/li\u003E\u003Cli data-list-item-id=\u0022e23c1eb450a19d5c4c9caaf6918894b68\u0022\u003EProf. Nian Liu \u2013 School of Chemical and Biomolecular Engineering\u003C\/li\u003E\u003C\/ul\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u0026nbsp;\u003Cstrong\u003EEngineering Tunable Hydrogel Electrolytes for Stretchable Batteries and Organic Electrochemical Transistors\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":" Engineering Tunable Hydrogel Electrolytes for Stretchable Batteries and Organic Electrochemical Transistors"}],"uid":"27707","created_gmt":"2026-11-13 21:25:59","changed_gmt":"2026-11-13 21:26:30","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-12-04T15:00:37-05:00","event_time_end":"2026-12-20T17:00:37-05:00","event_time_end_last":"2026-12-20T17:00:37-05:00","gmt_time_start":"2026-12-04 20:00:37","gmt_time_end":"2026-12-20 22:00:37","gmt_time_end_last":"2026-12-20 22:00:37","rrule":null,"timezone":"America\/New_York"},"location":"MoSE Room 1224","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"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":""}}}
