Streszczenie pracy dyplomowej:
Heart rate is important parameter that characterizes human condition. It is measured not only during medical examination of the patient but also during training and everyday physical activity. In such case the measurement device is often located directly on the chest in the form of the band or is integrated into training equipment. It often uses wireless transmission to send measurement data to the device that could be easily controlled by the user, like watch or smartphone. The wireless heart rate sensors are the subject of intense development that aims at improvement of measurement precision, user comfort and transmission reliability. The aim of this thesis was to design a complete heart rate sensor which would communicate with receiving station using wireless link. The sensor should be autonomous, battery operated device that could be located directly on the human body or integrated into the training shirt. To complete this project the following tasks were carried out: • theoretical consideration of methods for measuring the heart rate; • measurement system design; • selection of components and modules, hardware design; • development of software for signal processing (microcontroller) and visualization (PC); • launching the prototype of the sensor; • designing elements of the wireless link (Wilkinson power divider, printed antennas: narrowband patches and UWB PICA) for the two-antenna transmitting system; • simulations and measurements of the designed microwave elements; • elaboration of the Printed Circuit Board. The thesis consists of six chapters. Beginning with the introduction, it goes through two chapters that investigate the designing process of the heart rate sensor itself, where chapter two gathers the theory of human heart operation and chapter three addresses practical issues of heart rate measurements. Subsequent chapter four is focused on the RF topics - it delivers necessary theory, which immediately is put into practice in described designs. Chapter five presents the design of the common PCB, which merges designs from chapters three and four. Chapter six is a summary - it contains conclusions and remarks.
