Abstract: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 an… Show more
