Integrating self-powered medical devices with advanced energy harvesting : a review

This paper reviews self-powered medical devices integrated with advanced energy harvesting technologies. This article aims to explain the advantages of integrating self-powered medical devices with advanced energy harvesting technologies, outlining the transformation in healthcare system and patient experience. In today's world, we focus more on consuming energy harnessed from the environment and human body. This approach lowers down our emphasis on conventional power sources like batteries, power packs etc. As a result, the devices used in the medical sector have a longer lifespan, maintain continuous functioning, and improve patient comfort and mobility. Integrating advanced energy harvesting technologies (i.e., piezoelectric, thermal, solar, and electromagnetic) with medical devices plays a pivotal role in revolutionizing the healthcare sector. But there is still some research and development needed to enhance these technologies. This paper will set out by introducing some self-powered medical devices commonly used in healthcare, followed by their advantages, benefits, and challenges that the healthcare practitioners face. This review also discusses their biocompatibility factor which is crucial to use. Then there are examples of a few advanced energy harvesting methods that are being used which include: piezoelectric, solar, thermal, triboelectric and electromagnetic. As we go further, we will come across a table consisting of a comparison between these advanced energy harvesting technologies and their examples in the healthcare sector. The last section is future perspective and the conclusion highlights the transformative potential of this integration, followed by a future recommendation for advancing this field.
