The EcoSentinel project envisions a groundbreaking transformation in our relationship with nature to address pressing global sustainability challenges as biosphere integrity degradation, fostering a harmonious coexistence between technological innovation and environmental conservation; culminating in a community of Ecological Sentinels (EcoSentinel). Specifically, EcoSentinel leverages the biological processes and the resilient nature of living plants to give them the necessary means (i.e., energy harvesting and electromagnetic signal propagation) to become self-sustained digital nodes of a network able to autonomously monitor themselves. This revolutionary approach aims to enhance our capacity to safeguard forests and other ecosystems. The EcoSentinel technology will introduce a carbon-negative wireless communication system, powered by the ecosystem itself, enabling environmental monitoring to prevent and mitigate critical events such as wildfires and biodiversity loss. The EcoSentinel project proposes a new form of plant-plant interaction by elevating it to a digital level. By enhancing plants’ interconnection through cybernetical implants, we embark on a path to digitally transform the greenery. This unprecedented approach aims to establish a novel wireless plant-based communication system, using plants as natural antennas, uniquely powered by the integration of plant-microbial electricity generation seamlessly blended into the vegetation.
