This work exploits low-cost, low-power and innovative hardware solutions for bidirectional backscatter links at 2.4 GHz. Moreover, a custom backscatter tag for sensing and RFID application is designed and implemented, able to send data up to 60 meters away with packet error rate (PER) in the order of 3.7%. The tag is also capable of receiving data and its power consumption can be less than 0.27 mW for 4.5 seconds of continuous operation. The tag cost per unit does not surpass 5 Euros. The receiver of the tag is based on a custom, comparator-based design, using on-off keying (OOK) modulation. In addition, a solar energy harvesting system is designed, offering an energy-autonomous link. Based on this tag, a prototype environmental humidity sensor node is implemented and demonstrated.
