TriPhase

Triphase is the process of combining two E-Stim output signals into a set of 3 contact points, producing a set of sensations that are generally considered to be more '3D' like in feel. 

Triphase generally requires a dual channel unit capable of producing phase shifted output signals, such as the E-Stim Systems 2B or the ElectroPebble, and also requires the use of a Triphase cable set.
