Impedance measured between two stencil printed electrodes, different
distances apart, with different weights applied to them.  Dry
measurements were done with the electrodes placed directly onto the
skin, wet measurements had 0.05ml of water put on the skin first.

There was a delay of at least 10s between applying a mass and taking the
measurement so the impedance could stabilise.

The electrodes used were 28 × 28mm, doctor bladed then cut to size.
