Capacitive electrodes have been proposed to measure the electrocardiography (ECG) without direct skin contact. Unfortunately, capacitive ECG (cECG) measurements are very sensitive to various types of noise, and are therefore limited for heart-rate monitoring. The aim of the present study is to explo...
