Abstract
Systems and methods measure impedance across a user's chest during respiration to determine a rate of respiration. With AC-modulation contacts separated from impedance-measuring contacts, analog filtering to remove EMI, a bridging capacitor to remove DC noise, and digital filtering to further remove EMI, a user's respiration may be measured with the AC-modulation contacts and the impedance-measuring contacts placed at user extremities.
