  • Easy to Use

    Easy to Use

    Getting started with is simple. The blue digital display and 4-way joystick make light work of controlling your session.
    During stimulation you can see the exact session time remaining, the active current value in mA plus a real-time graph of the actual current.
    With a digital display and intuitive user interface is easy to use.
  • Recharging Dock

    Recharging Dock

    Included with every v2 is the dock.
    The dock connects to your computer via an included micro-USB cable.
    As well as recharging your v2 the dock serves as a Bluetooth Low Energy dongle. This allows the connect software to update your v2 via Bluetooth Low Energy without any additional hardware requirements.
    The dock is both a recharging station and bluetooth low energy adapter when connected to your computer.
  • ARM® Processor Powered

    ARM Powered

    Inside v2 is a 32Bit ARM® Microprocessor.
    Using advanced micro-electronics ensures accurate stimulation. Impedance changes can be detected and correct in 50µ seconds. This means target current levels are super-accurate and super-stable.
    Only the best components were used in construction from such manufacturers as Texas Instruments, Seiko and Panasonic.
    If you want the best, this is it.
    Powered by an ARM microprocessor and supported with components from Texas Instruments, Seiko and Panasonic - is designed to be super accurate and reliable.
  • Safety First


    The only device on the market to implement recommended considered safe guidelines for transcranial stimulation
    • Over usage prevention system
    • Current comfort calibration
    • CE certified to Medical Standard 60601:2.

    With triple locked current limiting circuitry and session audit logs this is the safest stimulator in the world.
    The safest stimulator money can buy
  • Time is Important


    It is important not to mis-use electrical stimulation through over or repeat usage. That is why the v2 includes a real time clock. It will warn you if you try to start a stimulation session too soon after your last session. It also times and limits each session to the maximum recommended length of 40 minutes.
    You can also use the timer to start your session upto 12 hours in the future. This is useful if you want a session to start when you are asleep.
    All session logs are stamped with the time they were started for your convenience.
    Includes a realtime clock so you can do timed starts, timed logs and also overuse prevention.

transcranial Direct Current Stimulation (tDCS)

tDCS mode current can be set from 0.1 to 2,0mA for session durations between 1 and 40 minutes. Voltage can be also be controlled from 10V to 60V. Actual current is logged every 50ms for an accurate record of the session. Featuring current ramp up and ramp down to make session start and end as comfortable as possible.

transcranial Alternating Current Stimulation (tACS)

tACS mode current can be set from 0 to 2mA for session durations of between 1 and 40 minutes. Frequency can be set between 0 and 300Hz in both unipolar and bipolar modes. A current offset between 0 and the target current can also be specified.

Double Blind Sham Option

You can set Sham to ON, and have no graph, or set sham to BLIND and the focus v2 will either show the real current graph or create a fake graph. Log file analysis post session will confirm if the session was real or sham. You can also set the current ramp up period for sham sessions.

transcranial Pulsed Current Stimulation (tPCS)

Set the duty cycle for pulsed current stimulation sessions. Log files are available in both CSV and binary format.

transcranial Random Noise Stimulation (tRNS)

Randomize the current, the frequency or both and set the range boundaries for each.
  • The Future

    Future Firmware

    An investment in a brain stimulator is an investment in your future. In an advancing world it's important that your stimulator is not limited to only today's technologies. That is why the v2 has an upgradeable firmware architecture.
    transcranial Direct Current Stimulation (tDCS) may be the best known due to its simplicity but tACS, tPCS and others are showing better results across many studies.
    So as new stimulation techniques are verified such as Pulsed and Random Noise, your firmware can be updated over the air to enable them.
    And beyond that we are researching personalised stimulation settings tailored to your exact brainwaves. firmware is regularly updated with the latest settings and modes from the world of transcranial stimulation research.
  • 3-axis Accelerometer

    Accelerometer v2 includes a 3 axis accelerometer.
    It provides raw data for X, Y and Z movements as well as slope detection, tap sensing, orientation recognition, g-force detection and inactivity sensing.
    This movement detection is used in the lucid dream program to stop stimulation when movement is detected. v2 includes a 3-axis accelerometer with smart functions for slope, tap and inactivity detection.
  • Small But Powerful

    Portable Size

    They say good things come in small packages and with the v2 we believe it to be true. was designed in London, UK with the aim of being both small and powerful.
    Weighing in at less than the battery found in some DIY stimulators yet generating an output 6x higher.
    Take it with you and you will always be ready.
