Researchers at the University of Oulu are developing sustainable 6G radio lenses using nanocellulose, a lightweight, low-loss material derived from Finland’s forest industry that serves as an environmentally friendly alternative to traditional plastics. These lenses are designed to focus high-frequency 300 GHz signals for faster data transmission while addressing the need for recyclable electronics through water-soluble, printable manufacturing methods. The technology integrates with emerging concepts like intelligent reflecting surfaces and structural electronics to support the computational and infrastructure demands of next-generation wireless networks. By combining advanced materials research with printed electronics, the project aims to create durable, high-performance components that balance performance with circular economy principles.
