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 monograph are low maintenance, inexpensive, and easy to deploy. Focusing on power, form factor, and cost as system design parameters, the author describes stickers that have simple circuitry and can sustain themselves while wirelessly communicating and responding to various human Interactions.

This work introduces four projects. SATURN is a self-powered flexible microphone and vibration sensor based on a triboelectric generator made from inexpensive everyday materials. ZEUSSS stickers extend the SATURN microphone by leveraging simple passive circuitry to add wireless communication capability. 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 light.

Self-powered Audio Triboelectric Ultrathin Rollable Nanogenerator (SATURN) is a self-powered microphone that is thin, flexible, and easily manufactured. This acoustic sensor takes advantage of the TENG to transform vibrations into an electric signal without applying an external power source. The sound quality of the SATURN microphone, in terms of acoustic sensitivity, frequency response, and directivity, is affected by a set of design parameters that I optimize based on both simulation and empirical evaluation.

Printed Flexible Electronics: In the last decade, the democratization of fabrication tools and techniques like inkjet and three-dimensional (3D) printing has opened the opportunity for wireless components such as antennas, inductors, and capacitors to be created in versatile form factor. Several different types of conductive inks like graphene, silver, graphite, and PEDOT:PSS on different substrates of plastic, wood, walls, and textiles have been demonstrated to create these components. It has opened avenues for sustainable wireless interaction stickers to be produced in thin, flexible form factors and even for the possibility of being embedded in different types of materials in the future.

The device, circuit, and system innovations described in this book provide a path toward interfaces that can be sustainably instrumented on to everyday physical objects and surfaces.
