In the Internet of Things (IoT) era, Wireless SensorNetworks (WSNs) are rapidly increasing in terms of relevanceand pervasiveness thanks to their notable real-time monitoringperformance across several fields, including industrial, domestic, military, biomedical, commercial, environmental, and othersectors. A highly attractive implementation of WSNs is assettracking with accurate data regarding the location and transportation conditions of goods, equipment, and the like. One highlypromising application of WSNs along these lines is the remotespeed monitoring of goods, ideally with battery-free sensor nodesthat do not require any maintenance. This, however, representsa major challenge in power supply management. The goal ofthis paper is to investigate Radio Frequency (RF) WirelessPower Transfer (WPT) architecture to power a battery-freemeasurement system with time-domain readouts, for the speeddetection of a moving sensor tag within a Wireless SensorNetwork infrastructure. The performance characteristics andkey features of a System-on-Chip (SoC) specifically designed topower a node through RF WPT will be discussed. The aim is toprovide a strategy and a model to estimate the speed of a specificbattery-free sensor that is powered by a transmitting hot-spot.Specific tests and experimental results are provided.
