“…One possible solution to this challenge is wireless power transfer (WPT), which can replace the need for batteries and cables. Various methods of WPT, such as microwave energy transfer, inductive coupling, and capacitive coupling have been reported in the past decade [5][6] [7]. However, these methods have been found to be ineffective for powering sensors within enclosed metal cavities due to the screening effect of metal, which prevents RF energy transmission, inductive and capacitive coupling from penetrating the metal enclosure [8].To address this issue, a new combined RF/Ultrasonic wireless powering (CRUWP) system is proposed in this work.…”

Sensors are vital tools in monitoring operating conditions and collecting data in scientific studies and engineering works. However powering sensors for a long term in harsh environments where physical access is difficult like enclosed oil pipes, sealed containers and underwater isn't straightforward. To solve this problem, a novel hybrid power supply technique is proposed, combining the advantages of radio frequency and ultrasonic power transmission. By harnessing the penetration capabilities of ultrasound and the long-distance wireless transmission benefits of electromagnetic waves, the proposed a combined RF and ultrasonic wireless powering (CRUWP) system to power sensors deployed in harsh environments. This article builds a system model and introduces 90% efficient time-sharing energy management scheme for coupled circuits to address the power density mismatch between RF and ultrasonic energy transmission. Furthermore, the power budget analysis is presented for the hybrid power supply scheme, showcasing its capability to deliver 1 mW output power to the load.
