University of Michigan Develops Photonic Fibers to Embed Invisible Barcodes in Textiles for Recycling and Authentication

Researchers at the University of Michigan have developed photonic fibers that can embed invisible barcodes directly into fabric. This advancement aims to improve recycling processes, enhance brand authentication, and facilitate tracking of textiles throughout their lifecycle. The technology introduces a new method for integrating detailed information into clothing without visible labels or tags.

The photonic fibers function as sophisticated markers within the fabric, enabling identification and data retrieval while remaining undetectable to the naked eye. These embedded barcodes hold potential for streamlining textile recycling by providing precise material composition details. Additionally, they offer a solution for verifying authenticity in branded products, addressing concerns over counterfeit goods in the fashion industry. The innovation also supports supply chain management by allowing manufacturers and retailers to track garments from production to end-of-life disposal.
