Riotee: An Open-source Hardware and Software Platform for the Battery-free Internet of Things
Kai Geissdoerfer, Marco Zimmerling
Abstract
The rapidly growing Internet of Things (IoT) can avoid the high cost and environmental burden of replacing trillions of batteries by using sustainable battery-free devices that operate maintenance-free for decades. To develop battery-free IoT systems, researchers and makers require a common platform that is versatile, affordable, and easy to use. However, limited availability and lack of support have prevented widespread adoption of previous battery-free platforms. We introduce Riotee, an open-source and commercially available battery-free platform that includes multiple boards, extensive software, and comprehensive documentation. We demonstrate Riotee's capabilities through a machine-learning application and present results from a user study involving students and customers, who rated its usefulness and usability highly.
