Description
Anna Ziobro and co-authors published this 2023 study on radio tags sewn into textiles. Such tags let garments carry identity chips for tracking and care. Their design splits the sewn antenna from the chip, linking the two through small inductive loops instead of wires. To improve the design, the team first had to learn what drives tag performance.
They built a math model covering each part's impedance, the loops' shared pull, and the voltage reaching the chip. Antenna shape and the tuning circuit both entered the math. The shared pull between loops mattered most above 800 megahertz, where it steered chip voltage strongly. Model results were checked against simulations and bench tests that varied loop spacing. The work gives makers a map of design trade-offs.
