Abstract
Today’s Internet of things (IoT) devices are bulky, expensive, require battery maintenance, and involve costly installation. In contrast, the interactive stickers introduced in this dissertation are low maintenance, inexpensive, and easy to deploy. Focusing on power, form factor, and cost as system design parameters, I create stickers that have simple circuitry and can sustain themselves while wirelessly communicating and responding to various human interactions.
This work will introduce four projects. SATURN is a self-powered flexible microphone and vibration sensor based on a triboelectric generator made from inexpensive everyday materials like paper and plastic. Next, ZEUSSS stickers extend a single SATURN microphone to have wireless communication capability leveraging extremely simple passive circuitry. MARS stickers improve ZEUSSS by allowing simultaneous multiple-channel communication capability for speech, swipe, and touch interactions in sub-microwatt power. Finally, VENUS adds feedback to the stickers in the form of a low-voltage display powered by the heat of a human finger or ambient room light.
The material device, circuit, and system innovations in this dissertation pave the way forward for a world where interfaces can be sustainably instrumented onto everyday physical objects and surfaces.
