Abstract

This paper introduces a sustainable IoT framework combining Plant-Microbial Fuel Cells (P-MFCs) and wakeup radio technology within the EcoSentinel project. P-MFCs generate renewable energy from plant-soil-microbe interactions, while wake-up radios enable ultra-low-power communication, addressing energy constraints in environmental monitoring. We evaluate the energy harvested by P-MFCs and the power consumption of wake-up-enabled nodes, demonstrating the feasibility of a self-sustaining sensor network. A tailored communication protocol ensures reliable, event-driven data transmission with minimal energy use. Applications include climate monitoring, precision agriculture, and urban ecology. This work highlights a shift toward bio-integrated, carbon-negative IoT systems, offering eco-friendly solutions for global sustainability. Future efforts will focus on optimizing efficiency and expanding functionality in diverse environments.

Key findings

  • P-MFCs can effectively harvest renewable energy from biological interactions to power IoT nodes.
  • Wake-up radio technology enables reliable event-driven data transmission with minimal energy consumption.
  • The combined approach supports the development of carbon-negative, eco-friendly sensor networks for diverse environmental applications.
