摘要： A sensor measuring skin impedance includes a reference electrode, a current carrying electrode, and a measuring electrode for measuring impedance for current flowing between the reference electrode and the current carrying electrode. The measuring electrode is recessed with respect to the reference electrode and the current carrying electrode, allowing the measuring electrode to make contact with a user's skin after the reference electrode and current carrying electrode make contact, resulting in greater measurement accuracy.
