The research applied to the biomedical applications of the UWB radar is directed to the identification of the possible new devices enabled by the technology, to the design and development of these devices and to the clinical tests of the obtained systems. Applications can be divided into two main sectors according to the frequency range used. For the conventional UWB radar microwave region: cardiac biomechanical evaluation; evaluation of thoracic movements OSA monitors (obstructive sleep apnea); soft tissue biomechanics research; images of the heart (Holter type echocardiography); images of the thorax. Along with systems for: cardiac monitoring; respiratory monitoring; SIDS (Sudden Infant Death Syndrome); study of the vocal tract. If an IR laser diode is used as the antenna, a more common radar (actually a hybrid between a narrow band and a broadband radar) is emitted which emits a short packet of electromagnetic waves whose echoes are sampled using a conventional UWB receiver equipped with a PIN. Possibilities include: non-invasive soft tissue biochemical study, noninvasive study of metabolic processes and IR spectral imaging.
Ultra Wide Band (UWB) technology has been developed in recent years in the context of low-speed short-range data communications. Due to channel bandwidth and low power characteristics, it provides a very different approach to wireless technologies compared to conventional narrowband systems. This makes it interesting in the area of medicine with many potential applications. In this chapter, the discussion focuses on the application of this technology in medical surveillance, and wireless body area networks.
On the other hand, UWB signals are suitable for accurate estimation of the distance between two spokes, even in multiple trajectories or without direct visibility, practically allowing the detection of the position indoors with an accuracy of 50 cm or greater. These characteristics can be exploited to perform a patient movement monitoring system in the hospital.
