Download or read book Radio Frequency based Wireless Monitoring of Sleep Apnoea Patient written by Yang Yang and published by . This book was released on 2012 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio frequency (RF) technology plays a significant role in the development of portable devices. Well-designed RF circuits may reduce the dimensions of portable medical devices, which will provide a more comfortable monitoring environment and may lead to more accurate diagnosis. This research is focused on the use of RF technology to develop a wearable wireless multi-parameter human monitoring system suitable for sleep apnoea research. In this thesis, an innovative system prototype employing RF and microwave technology is proposed. The thesis focusses on research into specified passive and active microwave circuits, 5.8 GHz signal propagation and concept approval at the system level. Specially-designed microwave bandpass (BPF) and lowpass filters (LPF) are presented in the thesis. These filters are designed based on the required specifications for the system. The designed BPF uses a combination of compact microstrip resonant cell (CMRC) and defected ground structure (DGS) technologies, which is able to satisfy a narrow bandwidth of 60 MHz and a selectivity of 0.22 dB/MHz, as required in the system specification. The LPF designs also use CMRC and DGS technologies. The achieved LPFs have the characteristics of sharp roll-off, low insertion loss, compact size and wide stop-bandwidth. 2.4 GHz and 5.8 GHz circular patch antennas are designed for the proposed wireless on-body transducer system, and the 5.8 GHz signal penetration capability has been tested in a simulated monitoring environment. The results prove that the 5.8 GHz microwave signal can be applied in the wireless monitoring of sleep apnoea patients. In the active design section, the design principles of a Class AB power amplifier and Class E oscillator using GaN HEMT technology are introduced. The designed circuits are able to achieve an appropriate output power level with a high power-added efficiency. These designs can be applied in a wireless power transmission system. Therefore, the battery can be completely removed from the on-body transducer, leading to significant saving of space. The cost of the portable transducer device may also be reduced at the same time. The sleep apnoea wireless monitoring system consists of two building blocks: an RF-based wireless on-body transducer and remote base station. The on-body prototype has a microstrip circular patch antenna, a project-oriented microstrip BPF, a frequency mixing circuit, a modulation circuit and a differential circuit for biomedical signal detection. The development of the on-body prototype was divided into five stages. For each of the developmental stages, the prototype underwent the phases of design, modelling, simulation, fabrication and measurement. The testing results for each phase and stage are very promising. The proposed prototype has been tested from baseband to 2.4 GHz RF band with excellent results.The research will benefit both sleep apnoea patients and hospitals by reducing the cost of the device, and the reduced size of the portable wireless patient monitoring device will enable patients to be more comfortable during diagnosis. The research reported in this thesis has made significant contributions in the following fields: (1) the development of a novel design of microstrip filters using CMRC and DGS, (2) successful 5.8 GHz signal penetration capability in a simulated environment for sleep apnoea monitoring, (3) the development of a high efficiency and high output power amplifier and oscillator for wireless power transmission and (4) concept approval of the proposed novel wireless on-body transducer.

Download or read book Novel Technique in Sleep Apnea Monitoring written by Vishnoukumaar Sivaji and published by . This book was released on 2014 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sleep apnea is a condition in which there are periods of pauses in breathing called apnea during sleep. It is usually diagnosed in sleep labs with a polysomnography system which monitors various parameters during sleep. Portable sleep apnea monitors are becoming common for use at homes. Commercially available sleep apnea monitors connect to a base station using several cables which leads to patient discomfort arising from restriction of freedom of movement. This thesis explores the feasibility of a completely wireless and mostly battery-free monitor that is small and inconspicuous to the patient while sleeping. As a proof of concept, the P2110 RF power harvester evaluation board from Powercast has been used to wirelessly power the sensor nodes and to send their data to a base station using a 2.4GHz radio. The proposed final application would involve a custom IC for power harvesting, amplification and telemetry.

Download or read book Contactless Vital Signs Monitoring written by Wenjin Wang and published by Academic Press. This book was released on 2021-09-20 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vital signs, such as heart rate and respiration rate, are useful to health monitoring because they can provide important physiological insights for medical diagnosis and well-being management. Most traditional methods for measuring vital signs require a person to wear biomedical devices, such as a capnometer, a pulse oximeter, or an electrocardiogram sensor. These contact-based technologies are inconvenient, cumbersome, and uncomfortable to use. There is a compelling need for technologies that enable contact-free, easily deployable, and long-term monitoring of vital signs for healthcare. Contactless Vital Signs Monitoring presents a systematic and in-depth review on the principles, methodologies, and opportunities of using different wavelengths of an electromagnetic spectrum to measure vital signs from the human face and body contactlessly. The volume brings together pioneering researchers active in the field to report the latest progress made, in an intensive and structured way. It also presents various healthcare applications using camera and radio frequency-based monitoring, from clinical care to home care, to sport training and automotive, such as patient/neonatal monitoring in intensive care units, general wards, emergency department triage, MR/CT cardiac and respiratory gating, sleep centers, baby/elderly care, fitness cardio training, driver monitoring in automotive settings, and more.
