Abstract
The utilization of wireless technology in traditional medical services provides patients with enhanced mobility. This has a positive effect on the recovery speed of a person after major surgical procedures or prolonged illness. Ultrawideband (UWB) radio signals have inherent characteristics that make them highly suitable for less invasive medical applications. This paper surveys our own and related recent research on UWB technology for medical sensing and communications. Some research perspectives in the aforementioned topics are suggested too.
Highlights
In recent years there has been an increasing interest in using ultra wideband (UWB) technology for short-range wireless communication interfaces [1]
The UWB radar can potentially be used in novel noninvasive sensing and imaging techniques owing to its high temporal resolution for detecting backscattered signals
We have described our current research on the application of this technology to noninvasive measurement of blood pressure
Summary
In recent years there has been an increasing interest in using ultra wideband (UWB) technology for short-range wireless communication interfaces [1]. This makes them difficult to detect and robust against jamming, potentially rescinding the need for complex encryption algorithms in tiny transceivers Owing to these characteristics, UWB has emerged as a solution for the radio communication interface in medical wireless body area networks (WBANs) [3]. Impulse radio (IR) transceivers have simple structure and very low power consumption, which facilitates their miniaturization [5,6,7] Another promising application of UWB as wireless communication interface is in capsule endoscopy. Imaging of surface and more deeply located structures such as breast tissue for cancer diagnosis is another promising application of UWB technology [19,20,21,22,23,24,25] This has the potential of taking over the role of X-ray mammography.
