Innovative biodegradable fiber technology addressing electronic waste issues
In a groundbreaking development, researchers at Seoul National University have created a biodegradable fiber technology for textile electronics that addresses the electronic waste crisis by combining functionality with environmental sustainability[1][2].
The current development involves fibers made from renewable polymers, with a conductive core of tungsten microparticles embedded in poly(butylene adipate-co-terephthalate) (PBAT), coated with polyanhydride (PBTPA). This composite fiber maintains performance requirements for electronic textiles, such as electrical conductivity of about 2,500 S/m, stretchability up to 38% without breaking, durability through more than 20 washing cycles, and resistance to over 5,000 bending cycles[2].
Moreover, the fibers perform well under movement and varying environmental conditions, as demonstrated by a prototype sleeve incorporating temperature sensors, EMG electrodes, and wireless power coils that function during use and biodegrade after disposal[2].
The fiber's biodegradability is a major breakthrough: once discarded, it decomposes naturally in soil or compost within months, leaving no toxic residues, unlike traditional e-textiles that persist for centuries in landfills[1][2][3]. This aligns with circular economy principles and could drastically reduce the environmental impact of wearable electronics.
Future plans include scaling manufacturing via compatible processes like dry-jet wet spinning—already demonstrated with over 10 meters produced in one run—and moving towards mass production of sustainable, high-performance wearable electronic textiles. Researchers envision this technology enabling textiles that power devices, monitor health, and then harmlessly vanish after use, revolutionizing industries ranging from fashion to healthcare[1][2][4][5].
With the production of the biodegradable fiber being scaled up, commercial use within five years is a realistic goal. Brands like Patagonia or Nike might adopt this technology for eco-conscious gear in the future[1].
However, challenges remain, including ensuring the durability matches traditional e-textiles and keeping costs competitive. Studies suggest that the lifespan of biodegradable electronics can be influenced by factors such as soil conditions, real-world use cases like bending and rubbing, etc[1].
In conclusion, the biodegradable fiber technology developed by Seoul National University researchers offers a promising solution to the electronic waste crisis while maintaining the functionality of wearable tech. The fiber, detailed in a July 2025 study published in npj Flexible Electronics, degrades naturally without harming the environment, making future wearables greener without sacrificing performance[1][2].
