<div><b>Title: Building Sustainable Computational Materials</b></div>
<div><b><br>
</b></div>
<div><b>Abstract:</b></div>
<div><font face="HelveticaNeue"><span style="text-indent: 36pt;">We are rapidly moving towards a world with a trillion internet-connected devices, from smartwatches to industrial sensors. However, computing has not yet disappeared into everyday objects and
surfaces we interact with, as Mark Weiser envisioned. Today's Internet of Things (IoT) devices are bulky, expensive, and battery-powered, making them environmentally harmful and heavily reliant on regular maintenance and replacement. </span><span style="text-indent: 36pt; background-color: rgb(255, 255, 255);">Four
system design challenges keep us from useful, integrated, and low-impact ubiquitous computational things: form factor, maintenance-free operation, low cost, and ecological impact or environmental sustainability. </span><span style="text-indent: 36pt;">With
this vision in mind, I build sustainable computational materials by rethinking the computing stack from the bottom up, going beyond off-the-shelf device components, and co-designing across novel materials, fabrication methods, low-power circuits, and industrial
design. To illustrate this, I will provide an example of an easy-to-retrofit, inexpensive, battery-free sticky note that can wirelessly sense acoustic vibrations and provide feedback. </span><span style="text-indent: 36pt; background-color: rgb(255, 255, 255);">This
work </span><span style="text-indent: 36pt;">will encompass three projects with increasing capability</span><span style="text-indent: 36pt; background-color: rgb(255, 255, 255);">. </span><a href="https://urldefense.com/v3/__https://dl.acm.org/doi/abs/10.1145/3214263__;!!BpyFHLRN4TMTrA!5FTrN-HW4VKx6OgUNQV_icsR_Ta3K1Bd689o5R80h79-Kn19UPubEvAWlcpi7NXS3sbRt0cdKPvZipEa_Zk7YU02z4KNH2I$" data-loopstyle="link" style="text-indent: 36pt;"><span style="color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); font-weight: 700; text-decoration-skip-ink: none;">SATURN</span></a><span style="text-indent: 36pt; background-color: rgb(255, 255, 255);"> is

feedback to the stickers in the form of a low-voltage display powered by the human body or ambient room light. </span><span style="text-indent: 36pt;">I discuss the potential application of sustainable stickers in interaction sensing, mobile health, and infrastructure
monitoring. I will conclude by laying a path forward for systems, toolkits, and applications that help progress the ambitious research agenda of sustainable computational materials throughout their full lifecycle - manufacturing, operation, and reuse or disposal.</span></font></div>

<div><font face="HelveticaNeue">Nivedita Arora is a postdoctoral researcher in the School of Interactive Computing at the Georgia Institute of Technology. She received her Ph.D. in CS and MS in HCI, advised by Gregory Abowd and Thad Starner at GT's Ubicomp
Lab. She is passionate about designing sustainability-first computing systems and exploring their applications. She works at the intersection of novel materials, low-power embedded systems, human-computer interaction, and design. Her research has been published
in top-tier ACM Systems and HCI venues such as IMWUT, UIST, and MobiSys. It has won several recognitions, including research highlights in Communications of the ACM and SIGMOBILE's GetMobile Magazine, two best papers (ACM IMWUT, ACM SenSys-ENSsys), and two
best posters awards (MobiSys, UIST). In addition, she was the recipient of the ACM UbiComp Gaetano Borriello Outstanding Student Award, Georgia Tech's GVU Foley Scholar, Outstanding GRA award in GT's College of Computing, Rising Stars in EECS, and GT's Faces
of Inclusive Excellence. You can find out more about her at </font><a href="http://niveditaarora.com/">http://niveditaarora.com/ </a></div>
