<div class=""><font face="HelveticaNeue" class=""><span class="" 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 class="" 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 class="" 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 class="" style="text-indent: 36pt; background-color: rgb(255, 255, 255);">This
work </span><span class="" style="text-indent: 36pt;">will encompass three projects with increasing capability</span><span class="" 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$" class="" data-loopstyle="link" style="text-indent: 36pt;"><span class="" style="color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); font-weight: 700; text-decoration-skip-ink: none;">SATURN</span></a><span class="" 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 class="" 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>
