Unlike other similar devices in the market, C One indicates ECG signals capacitively and not via galvanic electrodes. This results in the isolation of the signal from the body hence eradicating the need for spray or gel. This contact free procedure is evident in the illustration,. where the C One sensor combines a capacitor with the skin of the patient. A negative and or positive charge is initiated to main balance on the sides of the capacitor. Given this, the heart of the patient is constantly monitored and the ECG is able to display any changes. This technology also delivers accurate readings with low heart signal frequencies.
