HEAD-MOUNTABLE DEVICE AND ECG DETECTION SYSTEM FOR DETECTING AN ELECTROCARDIOGRAM SIGNAL COMPRISING SAID HEAD-MOUNTABLE DEVICE

The present invention refers to an eyewear, in particular smart eyewear comprising an ECG detection system for detecting an electrocardiogram (ECG) signal. Such ECG detection systems comprise a first electrode and a second electrode generally mounted on a first temple and on a second temple of a frame of an eyewear respectively; in details, the electrodes are mounted so as to face and contact the head of the user wearing the eyewear on opposite sides. In this way the ECG signal detected by the electrodes is due to the potential difference of two head opposite points. Moreover, thanks to this known ECG detection system the ECG signal can be continuously detected for all time period the user wears the eyewear. However, the ECG signal so detected usually results to be weak and noisy since potentials differences recorded on the head resulting from heart electrical activity are in the order of microVolts and moreover the ECG signal can also be overlapped to electroencephalogram (EEG) signal. Therefore, the monitoring based on the ECG signal detected with the known detection system is low-amplitue and not sufficient reliable and accurate. Another drawback of the known ECG detection systems is that the ECG detection is made continuously and so the amount of data to be recorded is very high, thus requiring high storage space. This implies high costs. The object of the present invention is to overcome the above-mentioned drawbacks and in particular to devise an eyewear with an ECG detection system for detecting an ECG signal more reliable and accurate with respect to the prior art.
