Last week, the U.S. Patent Office announced a patent of Google's ECG device, which shows that this device allows users to record their ECG anytime and anywhere by wearing it, so that they can know their heart activity level in sports or other scenes.

Google's ECG device patent

In the hospital, the doctor records the electrical activity of the heart by connecting multiple electrodes to the skin, and then connecting them to the positive and negative electrodes of the electrocardiograph galvanometer through the lead wire. Today, with the development of the Internet, this old ECG recording method should be eliminated. Google's device can help users record ECG anytime and anywhere.

Because ECG measures electrical signals at multiple points on the skin to record heart activity, it requires that the wearing device must be able to form "leads", such as the arm, chest, and waist must have contact points. Google's device has electrodes in contact with skin from bras, armguards to shorts, and electrode contacts have elastic deformation properties, which can adapt to the skin like clothes.

The device can help athletes and patients record ECG at any time, and can send ECG data to the ECS to record health status. Unlike heart rate, ECG can be simply measured through bracelets, watches and other devices. It requires more contacts and more complex lead modes, so the emergence of this device is more meaningful.
