Cobalt-Nanoporous Carbon Functionalized Nanocomposite-Based Triboelectric Nanogenerator for Contactless and Sustainable Self-Powered Sensor Systems

To address the drawbacks of contact-mode TENGs, such as wear and noise, and the need for contactless sensors post-COVID-19, this work explores MOF-based Nanoporous Carbon (NPC) materials. Co-NPC particles, synthesized from ZiF-67, are used to create a nanocomposite dielectric, improving charge storage and reducing charge dissipation in a contactless single-electrode TENG.

• Development of a contactless single-electrode TENG using a Co-NPC nanocomposite dielectric.
• Use of MOF-based Nanoporous Carbon (NPC) to improve charge density and extend charge decay time.
• Addresses issues of reliability, robustness, and contact-based interaction in traditional TENGs.
• First exploration of Co-NPC nanocomposite dielectrics as a negative material for TENGs.

Co-NPC particles were synthesized by carbonizing a zeolitic imidazolate framework material (ZiF-67). These particles were then used to create a nanocomposite dielectric for a contactless single-electrode TENG. The material's high surface area and nanoporosity were leveraged to improve the TENG's electrical power output.

The Co-NPC particles showed high surface area and nanoporosity, which synergistically improved the charge density and extended the charge decay time of the TENG. This work presents a promising material for developing more reliable and sustainable contactless TENGs for sensor systems.
