Abstract:

Battery-free devices offer a sustainable alternative to traditional battery-powered devices by eliminating the need for expensive, environmentally harmful, and frequently replaced batteries. Riotee is a next-generation platform designed for the battery-free Internet of Things (IoT). It features a base module, a debug probe for convenient firmware updates, and several expansion boards that enhance the platform’s capabilities without the need for custom PCB design. This talk will explore the key challenges of battery-free IoT, highlight the necessity of a battery-free development platform, and provide an overview of Riotee’s design and implementation.
