Tiivistelmä
In this paper, we present experimental investigations on washing durability of polydimethylsiloxane (PDMS)-conductive fabric composite, to validate its applicability for realization of flexible wearable antennas that can withstand multiple washing cycles. For this purpose, we designed an ultra-high frequency (UHF) radio frequency identification (RFID) passive tag antenna and fabricated several prototypes using such materials combination. Understanding the challenge of having a robust integration of lumped electronic component (e.g., RFID IC) on a flexible antenna, a new way to improve the interconnection has also been investigated. The tag prototypes were subjected to recurrent machine-washing tests, and after each washing cycle, their performance was analyzed mainly in terms of read range. The results reveal that, with a proper treatment on the antenna-IC fixture interconnection, the tag antennas developed with PDMS-conductive fabric composite can maintain their performance very well, showing a minimum degradation in read range after 15 cycles of washing.
