Experimental study demonstrates a printed chipless relative humidity sensor for sensor networks, highlighting sustainable low-energy device fabrication.
With the development of the Internet of Things (IoT), the resources and energy consumption of sensor networks are becoming a sustainability problem. Novel technologies like printed or flexible electronics pave the way to overcome some of these challenges. In this work, we present a printed near field communication (NFC) tag for Relative Humidity (RH) sensing fabricated by dispense printing. The sensing device is based on an LC tank that changes its resonant frequency with the humidity. The features of the device make it a good way to reduce resources and energy consumption.
