Enhancing sensor node autonomy: CMOS energy harvesting from controller area network data lines

This paper presents a novel approach to empower sensor nodes autonomously by harnessing energy from controller area network (CAN) data lines using CMOS technology. The proposed energy harvesting system (EHS) efficiently captures and stores energy from the CAN network, eliminating the need for frequent battery replacements and offering a sustainable and cost-effective solution for Internet of Things (IoT) applications. Through comprehensive simulations and experiments, the system's performance showcases remarkable metrics, including a rapid stabilisation time of 520 ns, ultra-low ground current of 10 μA, and an impressive energy efficiency of 89.1%. This innovative system not only demonstrates the effective extraction and regulation of energy from CAN data lines but also paves the way for sustainable and economical energy harvesting solutions in the realm of IoT applications, promising enhanced operational longevity for sensor nodes in diverse environments.
