Thync is a small triangular shaped device, that puts on the wearer's head. Headset then stimulates and activates nerves, so the user can either relax or energize. Brain neurons remain intact, the device only released electrical impulses. The effect is to remind stimulation massages, only more focused on user's head.[2]

Thync itself is wireless, connecting to the smartphone or tablet via Bluetooth (it's iOS only at launch, with an Android app coming by the end of 2015). Users can control Thync from the official app, where they can choose the length of the session. They can also adjust the strength of the brain-zapping there (each program follows a pattern of greater and lesser intensity, with cycles of peaks and valleys, but they can also manually raise or lower the overall strength).[3]

The project Thync costs $ 13,000,000 and started from October 2014. From 02.06.2015 is the device already publicly available and its price is 299$ (7 427,46 CZK to the 9.12.2015)).”[2]

Main characteristics

Thync delivers low-level electrical pulses to the nerves in the regions of brain. In this way get to change of mood. The producer strictly describes, how to change the mood occurs: "Human body balances the activity between sympathetic and parasympathetic nervous systems. The sympathetic system is associated with a "fight or flight" response to help regulate his reaction to stress. The parasympathetic system counteracts stress to help his enter a relaxed "rest and digest" mode".[4]

To the change of mood, Thync uses neurosignaling. Neurosignaling is on their website defined as follows: "Neurosignaling is the coupling of an energy waveform to a neural structure (receptor, nerve or brain tissue) to modulate its activity. Neurosignaling waveforms or Vibes consist of precise algorithms that bias activity of the sympathetic and parasympathetic nervous systems, so that you can enjoy a shift into a more energetic or relaxed state. Neurosignaling builds upon the best features of long-standing tDCS and TENS techniques by using pulsed currents with lower-intensity and higher-frequency outputs delivered through bio-compatible materials for greater safety and comfort."[4]

Neurosignaling technology that delivers signals to the brain through three neural pathways.

Thync is a wearable device whose main purpose is to change the mood. Users can choose 2 modes: calm or energy. One session takes 15 minutes.

Ethical Issues

So far there are known no ethical issues. In the future, but some may occur because it wasn't tested the long-term use of the device and it was only in 2015 released to the public.

Health Risks

There have been no significant issues regarding Thync’s safety profile, according to the company. It's known that many people already engage in alcohol, drugs, and other activities due to stress, anxiety, and mood problems. Thync may allow for a safer way to alleviate these problems.[6]

On the safety of Thync producers commented like this: "he Thync System is a low-risk transdermal neurostimulation device intended for lifestyle use at home, work, or in wellness applications to temporarily induce mental relaxation or calmness or to temporarily increase energy, awareness, and alertness. The Thync system is a safe and low-risk device. It is not intended to treat or diagnose any disease or medical condition."[4]

As already stated above, the Thync uses TENS and TDCs techniques. "Transcutaneous electrical nerve stimulation(TENS)is a non-invasive analgesic technique that is used to relieve nociceptive, neuropathic, and musculoskeletal pain."[7] Transcranial direct current stimulation (TDCS) is characterized as "the most widely publically-marketed kind of brain stimulation device for cognitive enhancement."[8]

Risk of these methods is wrong placement of electrodes. One people are right-handed, but other are left-handed. Reversing the polarity can be dangerous and can lead to impairment of brain. At best, it could mean ineffectiveness in producing enhancement.”[8] The manufacter this device recommends that people suffering to Reflex Syncope should be consult their physician before purchasing a Thync System.”[4]


In addition to the device changing of mood, it should help with sleep problems, reduce stress or the motivation to exercise. Producers also believe that as a result of introduction this device, the people could reduce consumption of coffee, alcohol and drugs.[9]

It is necessary mention that Thync is not intended to treat or diagnose any disease or medical condition. Thync is only enhancement device.”[4]

Public & Media Impact and Presentation

Apart from the fact, that the Thync company has its own website, facebook, twitter and youtube channel, there are the another web portals talking about Thync. One example of this is web portal Yates Buckeley (Computational Neuroscience)here wrote:

"When released as a product Thync was explained to be a high frequency current stimulation. Research in this area is new so the mechanism (like most brain things) is not well understood."[10]

The most frequently raised points of confusion:

  • most people find it relaxing
  • some do not / has some side effects
  • not well understood
  • long term use unclear
  • not a medical device”[10]

Yates also points out that, the recent study found a slight decrease in IQ as a result of basic electrical stimulation and he is afraid of a possible associating with Thync:

"I presume somehow it reset some connections. I have a slight concern Thync could have a similar effect but this is very hard to test."[10]


Public Policy

The FDA notified that with regard to its use and output characteristics, Thync is not subject to medical device regulations requiring pre-market clearance or approval.”[4]

Related Technologies, Project or Scientific Research

Thync has also already conducted a studies with hundreds of participants, and their chief science officer Jamie Tyler, is a powerhouse researcher in neuromodulation (with publications in Nature, PLoS ONE, Neuron, and Brain Stimulation). From the perspective of MedTech Boston, their responses were substantially better than those given by many other neurotech companies touting their wares on the convention floor of CES.[11]

The company Thync published 2 studies that are conceerned with their product. First study is called "The tolerability of transcranial electrical stimulation used across extended periods in a naturalistic context by healthy individuals.". This study examined the safety and tolerability of device. The research involved 100 healthy individuals (63% males and 37% female). It was conducted and observed a total of 1905 treatment sessions (sham= 636, tDCS= 623, and tPCS= 646) on a total of 100 subjects (sham= 37, tDCS= 33, and tPCS= 30). No severe adverse events were reported. Between or during the sessions rarely occured atypical discomfort,eheadache or migraine or skin condition.[12]

The second study is called "Transdermal neuromodulation of noradrenergic activity suppresses psychophysiological and biochemical stress responses in humans" and tested impact of Neurosignaling on participants. The study is very extensive because I write only the result. The data showed that "TEN can significantly dampen basal sympathetic tone compared to sham in a manner sufficient to modulate emotional thermoregulation as reflected in temperature changes of the face."[13]
