➀ An EU-funded project (€8.4 million) led by TU Graz and partners aims to develop battery-free IoT devices using wireless energy and backscatter communication;
➀ The technology utilizes distributed antenna systems for low-power transmission and passive communication, eliminating the need for batteries;
➁ Potential applications include retail (e.g., electronic shelf labels) and logistics (precise tracking), with challenges in processing weak signals over long distances.
