# Efficient Energy Harvesting Tech JBNU Researchers Debut a New Triboelectric Nanogenerators Design By Kalin Ned | Published 2026-01-10 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/efficient-energy-harvesting References: [prnewswire](https://www.prnewswire.com/news-releases/jbnu-researchers-propose-hierarchical-porous-copper-nanosheet-based-triboelectric-nanogenerators-302655994.html)  A research team from Jeonbuk National University has set its sights on efficient energy harvesting by developing a novel design for triboelectric nanogenerators (TENGs). The innovation utilizes a hierarchical porous architecture within two-dimensional copper nanosheets. The researchers maintain that their design represents a materials science advancement that will help overcome historical limitations in wearable energy-harvesting technology, specifically addressing poor electrical output and mechanical fragility by restructuring the internal morphology of the metallic sheets. The reconfigured material for efficient energy harvesting demonstrates substantially improved performance. It maintains functional stability across extensive stress cycles while also providing auxiliary capabilities such as shielding against electromagnetic interference and generating heat through electrical resistance. All of this is reportedly achievable via a scalable spray-coating fabrication method.
