1. An electrochemical sensor for in vivo use, comprising:

  • a substrate;

    a working electrode formed on or in the substrate and having multiple working electrode areas exposed for contact with a body fluid;

    a second electrode formed on or in the substrate and having at least one second electrode area exposed for contact with a body fluid; and

    the multiple working electrode areas and the at least one second electrode area comprising a symmetrical arrangement, wherein a symmetrical potential distribution is produced when an AC (alternating current) signal is applied to the sensor.
