Telectrodes are used for various ECG tests. It uses an Ag/AgCl sensing element and Hydro-gel for adhesion. An Ag/AgCl sensing element has the a best sensitivities and the solid adhesive hydro-gel has very low impedance. Hydro-gel’s main advantage is one of reducing movement artifacts by increasing the bond between the skin and the sensing element. The adhesive gel stocks both the skin of the patient and to the sensing element, so that movement artifacts can be significantly lowered.
