The GRAPHERGIA project collaborated to release a new scientific publication in a journal, a contribution led by our partner ESYCOM, a laboratory attached to the Université Gustave Eiffel. This paper, "Power management technologies for triboelectric nanogenerators”  was published in MRS BULLETIN | VOLUME 50 • MARCH 2025. 

It shares research on the GRAPHERGIA project’s Work Package 4 ‘Advanced electrical modelling and efficient power management of TENGs for energy harvesting and self-powered sensing IoT applications. 

GRAPHERGIA’s Scientific Paper Abstract

A triboelectric nanogenerator (TENG) is a device that utilizes contact electrification and electrostatic induction to convert mechanical energy into electrical energy. It enables self-powering of electronic devices by harvesting mechanical energy from the environment. Its applications include biomedical devices, wearable electronics, and Internet-of-Things (IoT) sensors. Extracting electrical energy from TENG remains challenging due to its time-varying nature and low internal capacitance. Effective power-management techniques are essential for TENG energy-harvesting systems, yet research on dedicated integrated power-conversion methods is currently limited. Given the growing interest in TENG, a comprehensive exploration of energy-harvesting systems is critically necessary. This article synthesizes and compares current advancements in triboelectric energy-harvesting systems, emphasizing strategies to enhance output power through various power-conversion techniques. Additionally, it explores techniques employed in other energy-harvesting systems to inspire innovative approaches in TENG system design.
