The SmartVest is a 12-channel digital vest for medical purposes that delivers 3D images in a 360-degree all-round vision and enables health monitoring of cardiac activity. The inside of the vest was interwoven with 10 flexible electrodes to record bioelectric pulses in the human body in real time. The electrocardiogram of the 12-lead ECG signals allows a direct analysis to monitor the health status of the heart of the patient or athlete. Particularly innovative are the fabric sensors. They do not require liquid contact to support the conductivity of the skin.
