Technical developments in textiles and electronics are providing the opportunity for the garments with improved functionality such as remote monitoring of physiological parameters. Developments of biomedical garments are already being in use for patient health control. In recent studies examination of cardiovascular system is performed with conventional methods; systemic hemodynamic parameters are acquired by electrophysiological methods such as Electrocardiography (ECG) and Impedance cardiography (ICG). Another convenient and potential method for assessment of cardiovascular system is photoplethysmography (PPG). The PPG absorption mode is the only one applied in commercial medical devices, while remission mode offers a wider range of application for cardiovascular monitoring and is more appropriate for integration into textiles. A prototype (head bandage) of a biomedical garment for remote monitoring of cardiac parameters (e.g. heart rate, R-R intervals) with an integrated wearable PPG device has been developed and tested. The aim of this study was to assess usability of the PPG device for a biomedical garment, and to test reliability of the heart rate data registered by the prototype and commercial medical device as a reference.
