Narbis’ flexible sensor arms offer movability to customize for individual needs and specific training goals and are configured to international 10-20 site-placement compatibility.

  • Gold plated sensor tips which are specially designed to gently comb through the hair to measure brain patterns. (Gold was chosen because it is biocompatible and a superconductor, so that it will not disturb your skin and it will work every time.)
  • Sensors are placed in a unique combination that allows for effortless and comfortable placement on all head and hair types with no special preparation and minimal noise and artifact.
  • The gold pins are attached directly to active circuitry which contain ultra-high impedance, low-noise integrated circuits
