On the other hand, to achieve a fully immersive intelligent environment, we might produce trillions of smart devices, but their current configuration (e.g., plastic housing, PCB board) will inevitably increase environmental burden. In my research, I work on creating computational materials with different encoded\u0026nbsp;properties (e.g., conductivity, transparency, water-solubility, self-assembly, etc.) that can be seamlessly integrated into our living environment to enrich different modalities of information communication. Meanwhile, the material intelligence will affect devices\u0027 usefulness from a sustainability perspective (e.g., device lifetime).\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EDuring my PhD, I presented five main works to scope the future pervasiveness of IoT devices while paying attention to their entire device life cycle. They emphasize different aspects that are crucial to constructing the\u0026nbsp;circular interactive material embedded environment\u0026nbsp;by balancing the tension between \u003Cstrong\u003Escalability\u003C\/strong\u003E and \u003Cstrong\u003Esustainability\u003C\/strong\u003E. Silver Tape is a simple fabrication technique leveraging inkjet printing circuits to transfer silver traces onto everyday surfaces without any post-treatment. This method allows users to quickly fabricate versatile sensors by leveraging the intrinsic material property (e.g., heat-resistive), and meanwhile, the transferred sensors can be \u003Cstrong\u003Erepaired\u003C\/strong\u003E when damaged (IMWUT20). Duco is the second project that negates the need for any human intervention by leveraging a hanging robotic system that automatically sketches large-scale circuitry. We have explored not only how to incorporate these computational abilities into our living structures but also created erasable ink that allows users to \u003Cstrong\u003Eerase\u003C\/strong\u003E the circuitry and embed the surface with new capabilities (IMWUT21). PITAS is a thin-sheet robotic material composed of a reversible phase transition actuating layer and a heating\/sensing layer to create shape-changing devices that can locally or remotely convey physical information such as shape, color, texture, and temperature changes. A distinctive \u003Cstrong\u003Erenewal\u003C\/strong\u003E process can be accomplished by immersing the material actuator in ethanol, allowing the devices a new life (CHI22). Next, Functional Destruction aims to further promote sustainability by designing devices that\u0026nbsp;\u003Cstrong\u003Edisintegrate\u003C\/strong\u003E\u0026nbsp;once they have fulfilled their purpose (CHI23). Most recently, I have further extended the disintegration of transient electronics for making fully \u003Cstrong\u003Erecyclable\u003C\/strong\u003E electronics to further enhance electronics\u2019 sustainability (UIST24, under review). I also discuss several key takeaways and future directions in terms of designing, using, and disposing of these novel sustainable edge devices and how they can be linked to bigger infrastructures (HotCarbon 23).\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003ECIRCULAR INTERACTIVE MATERIAL: Making Ubiquitous Computing More\u0026nbsp;Scalable and Sustainable\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"CIRCULAR INTERACTIVE MATERIAL: Making Ubiquitous Computing More Scalable and Sustainable"}],"uid":"27707","created_gmt":"2024-05-31 19:07:38","changed_gmt":"2024-05-31 19:08:35","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2024-06-14T13:00:00-04:00","event_time_end":"2024-06-14T16:00:00-04:00","event_time_end_last":"2024-06-14T16:00:00-04:00","gmt_time_start":"2024-06-14 17:00:00","gmt_time_end":"2024-06-14 20:00:00","gmt_time_end_last":"2024-06-14 20:00:00","rrule":null,"timezone":"America\/New_York"},"location":"GVU cafe","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":""}}}
