However, this field faces challenges in performance, stability, and scalable fabrication. To address these challenges, new materials are needed. One promising approach is the development of hybrid organic-inorganic systems that combine the advantages of both components. In this thesis, I engineer polyvinyl alcohol (PVAl) with mono- and polynuclear titanium oxide hydrate species to create hybrid systems with tunable electronic properties and device functions, depending on composition, enabling various electronic applications. For example, titanium oxide hydrates:PVAl hybrid of 60 vol% inorganic content exhibits both bipolar and volatile resistive switching at low voltages (~2 V), depending on electroforming. Another application is a hybrid-based UV sensor for personalized monitoring, enabling both real-time and cumulative detection. Finally, we fabricate and characterize hybrid-based organic thin-film transistors (OTFTs) using a 10 vol% hybrid system as the gate dielectric, showing superior performance compared to PVAl-based devices, highlighting the potential of the 10 vol% hybrid system as an advanced dielectric material. Overall, this thesis establishes titanium oxide hydrates:PVAl hybrids as a versatile platform for next-generation electronic and sensing applications.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003EEngineering Hybrid Organic-Inorganic Materials for Versatile Flexible Electronics\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Engineering Hybrid Organic-Inorganic Materials for Versatile Flexible Electronics"}],"uid":"27707","created_gmt":"2025-09-05 12:09:48","changed_gmt":"2025-09-05 12:11:51","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-09-08T14:00:00-04:00","event_time_end":"2025-09-08T16:00:00-04:00","event_time_end_last":"2025-09-08T16:00:00-04:00","gmt_time_start":"2025-09-08 18:00:00","gmt_time_end":"2025-09-08 20:00:00","gmt_time_end_last":"2025-09-08 20:00:00","rrule":null,"timezone":"America\/New_York"},"location":"MoSE 3201A ","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"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":""}}}
