Monitoring of cardiac activity provides timely intervention by doctors in case of emergency. Earlier, electrodes were used to control the work of the heart, however, with the invention of \(SKG). An ECG captures electrical activity with every contraction of the heart muscles, and an ECG controls the fluctuation of the chest from each heart beat. Thus, SKG increases the accuracy of the readings obtained using the cardiogram. Scientists from Texas have proposed the construction of a two-layer sensor. The first layer is designed to remove the ECG and is made of gold and polyethylene terephthalate (PET). The second layer is made of a piezoelectric material polyvinylidene fluoride (PVDF), generating electricity during mechanical vibrations. This layer is designed to remove SKG. Both layers are attached to the elastic sheet of a transparent 3M Tegaderm medical dressing. A device attached to the heart, placed on an elastic base, does not cause any inconvenience to the patient. The tested devices are “tied” to the computer with wires. However, the plans of the developers include the creation of mobile stand-alone devices that are paired with a smartphone using wireless technology. At this stage of development, the undeniable plus of the novelty is that it can be worn on the skin for several days without experiencing significant discomfort.
