1. A device for measuring an electrical signal occurring in body cells of an animal comprising:

  • a picafina having a generally cylindrical device body with a proximal extremity, a distal extremity, an inner lumen and an outer surface;

    a plurality of measuring electrode tips on the outer surface of the picafina in fixed relative positions at the distal extremity;

    a first plurality of wires running inside the lumen wherein the first plurality of wires have wires comprising at least one element selected from the group consisting of;

    electric power wires, binary information wires, and signal carrying wires;

    a plurality of first on/off switches, each of the first on/off switches associated with one of the measuring electrode tips for selecting the associated measuring electrode tip;

    a plurality of second on/off switches, each of the second on/off switches associated with one of the first plurality of wires running inside the lumen;

    a device connector at the proximal extremity of the picafina to connect the first plurality of wires in the lumen to additional wires outside the picafina device body, the additional wires outside the picafina for connecting to at least one element selected from the group consisting of;

    a measuring and/or recording instrument, an electric energy storage, and a control electronics;

    wherein the measuring electrode tips are configured to measure the electrical signal values at the body cells next to the respective measuring electrode tips; and

    a timer electronic circuit that controls the duration of the “

    on”

    time of at least one of the first or second on/off switches such that once one of the plurality of switches is turned “

    on”

    it is kept in the “

    on”

    state for a pre-determined time, after which the timer electronic circuit moves the switch to the “

    off”

    state.
