目前的工作描述了银纳米颗粒墨水在转移纹身纸上的喷墨印刷和低温烧结。我们的方法使银具有出色的分辨率和导电性，随后第一个安装在人体皮肤上的无源 UHF RFID 转移纹身标签与丝网印刷无源 UHF RFID 转移纹身纸标签相比具有改进的性能。此外，喷墨印刷的无源 UHF RFID 转移纹身标签与塑料基材上的铜蚀刻无源 UHF RFID 标签具有相似的性能。本研究比较了两种商用银纳米粒子墨水喷墨打印在转移纹身纸上的图像质量（分辨率）和电气性能。描述了获得电阻率是块状银电阻率 (1.59 × 10−6 ohm cm) 20 至 57 倍的高分辨率特征的最佳印刷和烧结参数。我们演示了如何通过在天线的特定区域有选择地沉积墨水，将无源 UHF RFID 标签的读取距离从 54 厘米增加到 68 厘米，同时将墨水用量减少 33%。此外，这种方法使得喷墨印刷的无源 UHF RFID 纹身标签的读取距离比银丝网印刷无源 UHF RFID 纹身标签（45 厘米）和类似于铜蚀刻无源 UHF RFID 塑料标签（75 厘米）的读取距离更大。此外，这项工作中的喷墨印刷无源 UHF RFID 纹身标签比屏幕和蚀刻无源 UHF RFID 标签（数十微米）薄得多（1-5 μm），因此，前者对最终用户更具吸引力。除此之外，喷墨打印与大面积制造技术兼容，并有潜力发展成为最有前途的RFID大规模生产技术之一。因此，这项工作代表了向人体转移纹身纸无源 UHF RFID 标签商业化迈出了一步。
The present work describes the inkjet printing and low temperature sintering of silver nanoparticle inks onto transfer tattoo paper. Our approach results in silver features of excellent resolution and conductivity and, subsequently the first passive UHF RFID transfer tattoo tags functional mounted on human skin of improved performance when compared to screen printed passive UHF RFID transfer tattoo paper tags. Moreover, inkjet printed passive UHF RFID transfer tattoo tags show similar performance to copper etched passive UHF RFID tags on plastic substrates. This study compares the image quality (resolution) and electrical performance of two commercial silver nanoparticle inks inkjet printed on transfer tattoo paper. The optimal printing and sintering parameters to obtain high resolution features of resistivities 20 to 57 times the resistivity of bulk silver (1.59 × 10−6 ohm cm) are described. We demonstrate how, by selectively depositing ink in specific areas of the antenna, read distance of passive UHF RFID tags can be increased from 54 to 68 cm whilst decreasing the amount of ink used by 33%. Furthermore, this approach results in inkjet printed passive UHF RFID tattoo tags with larger read distance than silver screen printed passive UHF RFID tattoo tags, 45 cm, and similar to copper etched passive UHF RFID plastic tags, 75 cm. Moreover, inkjet printed passive UHF RFID tattoo tags in this work are considerably thinner (1–5 μm) than screen and etched passive UHF RFID tags (tens of micrometers) hence, making the former more appealing to the end user. In addition to this, inkjet printing is compatible with large area manufacturing techniques and has the potential to evolve as one of the most promising RFID mass-production techniques. Therefore, this work represents a step towards the commercialization of on-body transfer tattoo paper passive UHF RFID tags.
