| dc.description | The growing need to extend the public health services to extramural care requires the development of ambulant devices that can continuously monitor a subject's biosignals throughout regular day-to-day activities. The increasing number of people with musculoskeletal diseases, such as chronic lower back pain, myopathy and myofascial pain syndrome, is driving the development of innovative monitoring and treatment concepts to relieve the burden on public healthcare services. An important biosignal often used in clinical diagnosis, medical treatment, and rehabilitation for patients with musculoskeletal disorders is electromyography (EMG). Conventional EMG measurements are done using contact electrodes such as needle electrode (nEMG) and surface electrode (sEMG) that require complex measurement process, limiting the efficiency of the EMG measurement and portability of the system. Recent technological developments in amplifier electronics allow the use of small capacitive EMG (cEMG) biosensors. These electrodes can measure the EMG signals without galvanic contact with the human body which overcome the limitations of the contact electrode. Since no direct permanent skin contact is required, capacitive electrodes are particularly suitable for integration in ambulatory measurement systems. Although in principle it seems possible to measure EMG capacitively, substantial research is still required to bring this technique to maturity. Therefore, the objective of this research is to develop a cEMG biosensor that can be applied to an ambulatory muscle activity monitoring system. The main components of the measurement system are the capacitive electrode with polyimide film and textile as an insulator, front-end preamplifiers, pre-processing filters, a data acquisition unit, and the user interface for data storage, analysis, and monitoring. An electrical model of skin-electrode interface was derived to determine the optimum skin-electrode capacitance of a cEMG biosensor. The capacitive electrode, front-end preamplifiers, and pre-processing filters were designed and fabricated. All the main components of the system were integrated and validated with a series of experiments. Experimental results showed that the cEMG biosensor insulated by polyimide film could measure EMG signal accurately and achieved extremely low noise floor of less than 2 mV. The EMG signals measured by the conventional wet contact electrodes and the cEMG biosensor were highly correlated with the correlation coefficient value of 0.86 to 0.90 without requiring any post signal processing. This cEMG biosensor also able to measure the EMG signal with textile as an insulator. This cEMG biosensor could overcome the limitations of the contact electrodes, yielding a comparable performance to EMG signals measured by conventional wet contact electrodes which makes it ideal for ambulatory applications.,Master of Science | - |
