Due to an increasing interest to wearable electronics, versatile electronics manu- facturing methods are needed for numerous applications. Brush-painting is a simple and fast additive manufacturing method for electronics, which involves only two process steps: painting and sintering. In our study, passive UHF RFID tag antennas were brush-painted through a stencil on two different fabric substrates by using only one layer of silver nanoparticle ink. According to our measurements, the tags on Fabrics 1 and 2 showed peak read ranges of over 8 meters and of 2 meters, respectively, both on top of the fabric and while embedded between two layers of fabric. The brush-painted tags also showed suitable on-body read ranges. However, the characteristics of the fabric substrate had a significant effect on the tag performance.
