Focus V3 tES Device

The Focus V3 tES device features tDCS (Direct Current), tACS (Alternating Current), tPCS (Pulsed Current), tRNS (Random Noise) stimulation, and an all-new tRCS (Rippled Current Stimulation). Inside foc.us V3 is a 32-bit ARM® Microprocessor. Using advanced microelectronics ensures accurate stimulation. Impedance changes can be detected and corrected in 50 microseconds. 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.

Rippled Current Stimulation

The new foc.us V3 features a rippled current stimulation (tRCS). tRCS is a dynamic tACS. The waveform ripples after the stimulation frequency as a function of time.

Accurate Stimulation

Inside foc.us V3 is a 32-bit ARM® Microprocessor. Using advanced microelectronics ensures accurate stimulation. Impedance changes can be detected and corrected in 50 µ 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.

Easy to Use

Getting started with foc.us is simple. The blue OLED 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.

Increase Peak Alpha

The dynamic frequencies entrain your brainwaves. The frequency shift then lifts entrained brainwaves higher.

Alpha Vision

Targeting the occipital lobe for increased visual awareness. See more with focus V3.

Time is Important

It is important not to misuse electrical stimulation through over or repeat usage. That is why the foc.us V3 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 up to 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.

Small But Powerful

foc.us was designed with the aim of being both small and powerful. V3 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. Weighing in at less than the battery found in some DIY stimulators yet generating an output 6x higher.

Safety First

The focus V3 implements recommended safety guidelines for transcranial stimulation

  • CE certified to Medical Standard 60601:2
  • Over-usage prevention system
  • Current limiting circuitry and session audit logs

Focus V3 Available Waveforms - tRCS waveform not shown

Focus V3 tDCS Waveform

tDCS - transcranial direct current stimulation

tDCS mode current can be set from 0.1 to 4.0 mA for session durations between 1 and 40 minutes. Voltage can be also be controlled from 10 V to 60 V. Actual current is logged every 50 ms for an accurate record of the session. Featuring current ramp up and ramp down to make session start and end as comfortable as possible.

Focus V3 tACS Waveform

tACS - transcranial alternating current stimulation

tACS mode current can be set from 0 to 4 mA for session durations of between 1 and 40 minutes. Frequency can be set between 0 and 300 Hz in both unipolar and bipolar modes. A current offset between 0 and the target current can also be specified.

Focus V3 tPCS Waveform

tPCS - transcranial pulsed current stimulation

Set the duty cycle and frequency for pulsed current stimulation sessions. You can set Sham to ON, and have no graph, or set Sham to BLIND and the focus V3 will either show the real current graph or create a fake graph.

Focus V3 tRNS Waveform

tRNS - transcranial random noise stimulation

Randomize the current, the frequency, or both, and set the range boundaries for each. tRNS is becoming increasingly popular in today's electrical brain stimulation studies.

Excellent

I found the Focus V3 to be an excellent device with all the necessary features I require when trusting a device to put an electric current into my brain! The safety features are good, I like the accuracy of the device and the different forms of stimulation. Good build quality and all the accessories and the carrying case are of similar high quality.

No title

No user manual or instructions whatsoever makes it quite a disappointment however I researched a plethora of information compared to many others that purchased this product. I’d prefer if each numbered setting actually said which setting it actually was, referring to tDCS, tACS, etc. However it doesn’t so you’re experimenting altogether. If you didn’t buy the EEG cap you also basically got ripped off because that is where you could really get the best use out of this machine, otherwise you wasted your time and energy and should’ve purchased anything other than this if you were only interested in tDCS. Thank you for asking for this review. Please bother to look into scientific studies like I did as well.

I love this product I bought 6 of them

Unfortunately one of my devices won’t turn on so I’m trying to figure that out ),:

Thank you for your feedback. We are glad you love your devices. A support agent will reach out to you to assist with that device.

Works As Intended

So far, so good. I've seen a positive difference in my mental cognition and mental health.

Great Start

Only 30 minutes of therapy so far but working. Seeing lights not through my eyes is an impressive start. I need "montages for dummies" though.
