Abstract
A disclosed apparatus includes a first signal line configured to couple signals from a first electrode to a signal detection circuitry for measurement of biometric signals sensed by the first electrode; a second signal line configured to couple signals from a second electrode, which is different from the first electrode, to the signal detection circuitry for measurement of biometric signals sensed by the second electrode; and a coupling circuitry configured to selectively couple the first signal line and the second signal line to a common electrical potential so as to equalize electrical potential difference between the first electrode and the second electrode.
