The study presents an assessment of battery-free Radio Frequency Identification (RFID) based wireless sensors, which have been popular in recent years. RFID technology is evolving into wireless sensors. Furthermore, the study discuss the many components of these battery-free RFID-based wireless sensors, as well as the five basic topologies that turn a simple RFID chip into a battery-free wireless sensor and current implementations of these topologies. The read range is critical in battery-free wireless sensors. As a result, we'll go through how each sensor component affects the read range and how each architecture uses these components to maximise read range, complexity, and/or cost and also address possible future directions that might aid in the advancement of RFID-based wireless sensor technologies.
