Register to view prices



Complete EEG recording cap with 34 (32 signal electrodes, ground and reference) built-in Multitrode electrodes. Layout in accordance with "AASM manual for the Scoring of Sleep".

Black fabric, Sub-Inion-type cap and fabric is made with high elasticity (High Comfort) for optimal fit and comfort through the night.

All electrodes are Multitrodes with sintered Ag/AgCl sensors. They are buttoned directly into the cap (total height 3,5 mm) or can be attached to the skin with double-sided adhesive rings. All electrodes are number-labelled at the sensor end and name-labelled at the socket end.

The cables are fixed loosely to the cap in a downward direction with nylon threads for optimal comfort. The length of cable trees is approx. 120 cm. 

The cable trees end in 1.5mm safety sockets, and come inserted into an electrode input box EIB32.
Corresponding 50pin flat ribbon cables are available separately.

Fabric, elasticity

Our caps are made with two different fabric elasticities.

The medium elasticity or 'High Precision' fabric provides a precise reproduction of electrode positions, across and within subject recordings, a longer life span for general wear and tear, and a quick drying time.

The high elasticity or 'High Comfort' fabric provides an optimal fit for a larger variety of head shapes, and due to its softness is great for children or participants with a sensitive scalp.

On our webshop we sell caps according to our standard recommendation, which depends on the size of the cap: 

  • 52 cm and above are manufactured with High Precision fabric;
  • 50 cm and below are manufactured with High Comfort fabric.



We provide caps in a range of sizes for human participants at any age.

Cap sizes reflect the participant's head circumference, measured at the hat line and expressed in even, two centimetre increments. They normally feature as the final 2 digits on our cap order codes (e.g. BC-64-UCMW-56).

Typical adult head sizes:

  • 62
  • 60
  • 58 (average male)
  • 56 (average female)
  • 54

Children's head sizes approximately:

  • 54 (11-14 years)
  • 52 (5-10 years)
  • 50 (3-4 years)

Infant head sizes approximately:

  • 48 (2 years)
  • 46
  • 44 (7 months)
  • 42
  • 40 (3 months)
  • 38
  • 36 (newborn)


In contrast to other EEG cap manufacturers, Easycap uniquely offers two standard cap cuts.

For participants with oval or rectangular head shapes, we offer the "Caucasia cut". It is a popular choice worldwide.

For participants with rounder head shapes, such as those with an Asian heritage, we also offer the "Asia Cut". We developed these in collaboration with researchers in Asia, therefore these caps are the first choices for laboratories in an area with a high demographic of asian participants such as China, Korea, Japan and Taiwan.
