  报告人简介: 

  Dr. Renyun Zhang received his PhD in Biomedical Engineering at Southeast University in 2007. He joined Mid Sweden University in 2008 as a Postdoc financed by Sundsvall Municipality, Sweden. He is now an associate professor in nanotechnology at Mid Sweden University. His research interests focus on materials development for triboelectric nanogenerators and the utilization of the human body’s triboelectric charges for sensors and healthcare.  

  报告摘要: 

  Triboelectric materials are fundamental to the functioning of triboelectric nanogenerators (TENGs) and self-powered sensors. Engineering polymers like PTFE, PDMS, and polyamide are commonly used due to their significant triboelectric effects. However, the development of materials for TENGs faces two primary challenges: the need for innovative materials that exhibit high triboelectric effects, such as composites, and the limited application of traditional engineering polymers. For large-scale deployment, there is a requirement for substantial quantities of these polymers, which is problematic given the increasing restrictions on single-use plastics, particularly in Europe, where they will be limited starting from 2030. Cellulose-based materials have shown promise in addressing these challenges.
