Tripolar concentric ring electrode (TCRE) sensors have unique properties. These sensors have been used to acquire various bio-signals such as: electroencephalography (EEG), electrocardiography (ECG), and electromyography (EMG). Compared to conventional disc electrode signals TCRE EEG (tEEG) has four times better signal-to-noise ratio, eleven times better mutual information and spatial resolution....
Each nerves and muscles of human body will generate potentials, voltages, and electrical field strength and known as bio signals such as electrocardiograph (ECG), electromyography (EMG), electroencephalogram (EEG), and electrooculogram (EOG). The signals may be acquired through non-invasive surface Ag/Ag Cl applications although the generated signals exist in very low levels of voltages. All the bio...
Recording of biopotential signals is uneasy as interference and noise can come from the preparation of the subject, environment setting and other biological signal. The circuit design in acquisition system must good and meets specification as is not distort original signal and safe to patient. Classic design of biosignal acquisition system usually use third electrode as reference potential. The third...
We describe a new course in Bioelectric Potentials, offered to seniors in a 4-year Electrical Engineering program, that integrates bioelectric mechanisms, numerical methods and simulation, hardware design, and technical writing. The course focused on mechanisms governing the generation of bioelectrical signals together with measurement and analysis techniques in muscle and nerve electrophysiology...
The contribution of the epi- and endocardial as well as the myocardial electrical activity to the body surface potentials was investigated in this study. A volume conductor model including a realistic anisotropic ventricular model was built up and the forward problem of electrocardiography was solved for four different rhythms. The results show, that the body surface potentials depend to a high degree...
