Some of the key players operating in the global ECG sensor market are Texas Instruments Inc., Neurosky, Analog Devices Inc., Shimmer, MikroElektronika D.O.O.,Medtronic Plc, GE Healthcare, Philips Healthcare, GE Healthcare and Siemens Healthcare among others. Heartbeats are measured through the bioelectrical signals consisting of very low amplitude generated by specific cells in the heart (SA node). The ECG sensor monitors the electrical energy generated during the heartbeat. The difference in electrical energy is observed by the two leads and referenced to the ground signal. The ECG sensors consists of electrodes, that connects electrocardiograph to the patient’s skin and the patient’s heart beat signal is tracked. An ECG device on the smartphones has made it possible for humans to track heart and other health related activities. The use of an ECG device through a smartphones has given rise to opportunities for people to monitor their health and pay attention to their heart beats....
