1. A method for obtaining an electrical signal from a patient at the patient'"'"'s skin, said method comprising:

  • locating a dermal area of said patient;

    a user statically contacting, with a probe, said dermal area and allowing said probe to dynamically vary a pressure applied by said probe to said dermal area, said probe comprising;

    a stationary element to stabilize said probe against said dermal area;

    a probe tip operably connected to a biasing element to apply said pressure to said dermal area;

    a detector operably connected to said probe tip to detect an electrical signal at the patient'"'"'s skin corresponding to said pressure;

    a feedback ioop connected to said detector to provide a feedback signal containing information with respect to said electrical signal at the patient'"'"'s skin;

    said biasing element connected to said feedback loop to receive said feedback signal and operating to dynamically adjust said pressure in accordance with said feedback signal; and

    obtaining, from said probe, an electrical signal at the patient'"'"'s skin.
