A Review on Comparative Analysis of WPT Based Rectennas for Various Biomedical Applications

Abstract
Modern day medical science relies extensively on medical equipment and sensors, which are revolutionizing healthcare through real-time monitoring, advanced diagnostics, and customized treatment procedures. Continuous monitoring of vital metrics is made possible by technologies like wearables, biomedical sensors, and implanted devices. It enables for remote patient monitoring and extends access to healthcare, especially in underprivileged areas. Continuous real-time data collecting facilitates early abnormality discovery, allowing for rapid medical attention and improved treatment and cure for patients. A major breakthrough in this area is wireless power transfer (WPT), which has enabled up possibilities for wearable and implanted medical devices that are less intrusive and more patient-friendly. WPT systems relies on the rectifying antenna, also known as the rectenna, to transform RF energy into DC power. Considering its crucial role in supplying power to biomedical devices, an in-depth examination of various rectenna designs is essential to identify the most appropriate configurations for specific healthcare applications. This article covers an in-depth review of various rectenna designs, evaluating their compatibility, size, and efficiency to determine which designs are best suited for biomedical applications.
