1. An apparatus for gathering data, the apparatus comprising:
a band configured to be worn by a subject, the band comprising a first electrode configured to capacitively or conductively couple with a body of the subject while the band is worn by the subject;
wherein the first electrode is a non-adhesive, dry electrode;
a second electrode configured to capacitively or conductively couple with something other than the body of the subject; and
a circuit coupled to the first electrode and the second electrode, the circuit comprising:
a first shield actively shielding the first electrode;
a second shield actively shielding the second electrode;
driver circuitry coupled to the first shield and the second shield; and
a third shield surrounding the driver circuitry and located physically between the first shield and the second shield, the third shield electrically insulated from the first shield and the second shield;
wherein the circuit is configured to detect a signal according to a first instantaneous potential at the first electrode and a second instantaneous potential at the second electrode.
