In the National Technology Project (NTP) OOG 2.0 we develop together with Thales, NLR, and TNO a field testable prototype of a remote identification system for its use in military and personal security applications. The general functionality of the concept was demonstrated in a preceding project, whereas now the focus is on technical maturity and long-distance functionality. One part of the system is based on a smart textile patch that contains fluorescent optical fibers (POFs) which are bundled and connected to a photodiode. This photodiode is part of an electronical system that reads out the light signal and subsequently communicates back to the interrogator. In order to optimize the existing prototype, we explored different fluorescent materials, used different textile production technologies such as embroidery and weaving, and improved the connection of the fibres towards the photodiode. Depending on the weaving pattern, the protection, the visibility as well as the light uptake of the fibers is influenced. By testing different designs, we were able to find an optimal pattern that ensures a high light-to-signal ratio while keeping a low profile in the uniform. By addressing the challenges using different expertises such as textile technology, material science, product design and electrical engineering, we developed an improved prototype which succeeded in the long-distance trials. Within the final phase of the project the focus is on the textile integration, alongside with a proper component protection.
