actiCAP slim/snap

actiCAP slim / snap: Next generation active electrode systems

The actiCAPs have been a go-to solution for reliable and flexible high-quality EEG recordings for some time. We kept on improving the design of our active electrodes and here present the latest versions: actiCAP slim and actiCAP snap.

General active electrode features

• • Higher impedance recordings: Active circuits for impedance conversion are integrated directly in the actiCAP slim electrodes. Impedance conversion already at the electrode level makes it possible to achieve outstanding signal quality even with higher impedances compared to conventional passive electrodes. Hence the preparation time per electrode is reduced tremendously.
  • Wide hardware compatibility: Connects to any Brain Products amplifier and a large range of EEG amplifiers from other manufacturers.
  • Per-electrode LED impedance feedback: Multi-color LEDs in the electrodes indicate the impedance ranges. This makes electrode preparation very convenient and fast, since the feedback is given directly at the electrode level without the need to look at a computer screen (e.g. 64ch in approx. 10 minutes).
  • Easy electrode replacement: actiCAP electrodes are very sturdy; however, in the event that an electrode fails, flawless replacement of single electrodes is possible.

Features of actiCAP slim active electrodes

• • 3 times thinner: The actiCAP slim is a fully active EEG electrode with impedance conversion circuitry and multi-color LED impedance feedback scaled down by a factor of three.
  • More lightweight: Less total weight and a low center of gravity reduce motion artefacts. The lower weight per electrode makes a high-density cap significantly lighter and hence more comfortable to wear.
  • More robust: The new design of the electrode comes with flat pellets that are covered by the electrode housing from the sides. This protects the pellet from accidental damages.
  • Easier preparation: The larger opening in the actiCAP slim makes the electrode preparation even easier. It now allows the usage of paste for long-term recordings like in sleep research!
  • The lower profile (now 6 mm) of the actiCAP slim makes it ideal for TMS applications. This allows positioning of the stimulator coil very closely to the head, resulting in minimal loss of TMS pulse power. Combining actiCAP slim with our high sampling rate actiCHamp amplifier, will give you the benefit of ultra-short artefacts.

Features of actiCAP snap electrode holders

• • Easy-to-use holder that further enhances usability and gives you the flexibility to mix and match electrodes with caps sizes and cap electrode arrangements.
  • Allows inserting and removing actiCAP slim electrodes with just a “snap” and a minimum amount of force. Still provides firm hold, also in mobile environments.
  • Different holder colors speed up the setup and prevent electrode placement errors.
  • Gives the flexibility of using a single electrode bundle with different cap sizes or combining multiple bundles for one high-density electrode arrangement.
