WIRELESS SENSORS IN MEDICAL FIELD: REVIEW

Abstract

As a groundbreaking solution to healthcare, continuous health surveillance using cellular body field networks of implantable and portable medical devices is imagined. This vision has been taken to the brink of life by exponential developments in biomedical sensors, low-power electronics, and wireless communications. The purpose of these applications is to ensure that the critical parameters of patients are tracked constantly, thus allowing them freedom of movement. In doing so, WBANs result in increased healthcare efficiency. Primary issues do need to be tackled, however. In the field of wireless sensors for medical uses, this paper reviews the latest state-of-the-art. It aims to present both wearable and implantable devices with recent developments. In healthcare, meeting the promise of wireless sensor networks (WSNs) needs to overcome a range of technological challenges. Also, this paper discusses the problems that arise in the different layers of Open Systems Interconnection (OSI) and highlights potential areas of study about the use of wireless sensors in healthcare applications.
