The research team of Professor Jaeyoung Park from the Department of Electronic Engineering at Kwangwoon University has synthesized Poly-DADMAC (Polydiallyldimethylammonium Chloride) and PEO (Polyethylene Oxide) polymer electrolytes, applied electrospinning technology, and developed composite nanofiber materials with very high electric positivity for the first time in the world. Using these materials, they successfully developed a high-output wearable triboelectric nanogenerator and power-free pressure sensors.

The research was supported by the Ministry of Science and ICT under the National Research Foundation's Mid-Career Researcher Support Program (NRF-2020R1A2C2012820) and the Ministry of Trade, Industry and Energy's Industrial Technology Innovation Program (RS-2022-00154983, Development of Autonomous Power Sensor Platform for Low-power Sensors and Actuators). The research results were published in Advanced Functional Materials (IF: 18.8), the world's leading journal in functional materials and devices, by Wiley. (https://doi.org/10.1002/adfm.202403899)
