A bio-impedance signal simulator (BISS) for research and training purposes

A Bio-Impedance Signal Simulator (BISS) is developed based on the models of the impedance cardiography (ICG) and impedance respirography (IRG) signals. With the aim of imitating the real ICG and IRG phenomena, the ICG and IRG signals are modelled and combined with motion artefacts and Gaussian noise. The simulator allows the user to load different predefined human activity states such as resting, standing, walking, and running. Moreover, and importantly, the user can also control the parameters as per his/her needs and generate Electrical Bio-Impedance (EBI) datasets for further processing. Possible applications of BISS include research (e.g. performance evaluation of cardiac and respiratory separation algorithms) as well as teaching and training in physiological courses. To the best of our knowledge, BISS is the first EBI signal simulator that imitates the real ICG and IRG signals phenomena.
