Due to an increasing interest to add functionality in various products, versatile electronics manufacturing methods are needed for numerous applications. In this letter, ultra-high-frequency (UHF) radio frequency identification (RFID) tag antennas manufactured by brush-painting directly on wood veneer substrate were examined. Silver and copper nanoparticle inks were used in antenna manufacturing. According to our measurements, brush-painted silver and copper nanoparticle UHF RFID tags showed read ranges of 5 and 3 m, respectively, even when embedded inside wood layers. These read ranges are sufficient for many applications, e.g., in construction and packaging industry, where wood is a common material. The novel manufacturing process, its applications, and the achieved tag performance results are presented in this letter.
