Powering sensors with rf field
1 like608 views
The document discusses powering sensors using RF energy harvesting. It describes how RF energy harvesting can power sensors without internal batteries by collecting ambient RF energy from sources like cell towers. This eliminates issues with batteries like cost, space needs for replacement, and maintenance. The document outlines potential applications of batteryless RF-powered sensors in areas like food transportation monitoring, retail and restaurant inventory tracking, and external equipment monitoring. It also discusses the technology behind RF energy harvesting sensors and some of the challenges involved in implementing these systems.
