In addition to treating diseases, it is important that more effort is on monitoring and maintaining the well-being of individuals. In this thesis work, we focus on the non-invasive signal acquisition and signal processing of biomedical vital signs for ubiquitous healthcare. These vital signs include electrocardiography, pulse oximetry, Stethoscope, and blood pressure. Information and communications technology is required to develop and deliver high-quality and efficient healthcare. We discuss the sensor technology, develop the schemes of digital signal processing, communications and networking, as well as implement an e-health system with special applications to elder care.en-USBaylor University theses are protected by copyright.
