'amofit S' is a wellness device worn like a necklace that improves sleep, stress, and anxiety. This device generates and delivers mild electromagnetic signals to the chest branch of the vagus nerve for stimulation. The cVES (cervicothoracic vagus electromagnetic stimulation) applied to 'amofit S' is a unique neuromodulation technology that is directly involved in the regulation of the autonomic nervous system by stimulating the cardiac branch of the vagus nerve and activating the vagal tone and parasympathetic nervous system. cVES is a non-contact neuromodulation technology with 9-inch radius of effective range. In addition, in the first clinical trial that we conducted, we obtained a clinical result in which the activity of the parasympathetic nervous system increased by more than 275% within 24 hours.

Suite a mon avis pour un problème sur…
Suite a mon avis pour un problème sur l’appareil, la société a été très réactive. Problème signalé samedi. Aujourd'hui il m’ont contacté par émail pour savoir le problème. Après cet échange j’ai reçu un mail pour m’indiquer qu’il m’envoyé un nouvel appareil et un bon de retour pour l’ancien.
Donc société très sérieuse. Et leur système pour le nerf vague fonctionne très bien sur moi.

I charge it every night but it only stays on about 2 hours. I try & ouch the top center but I can’t get the light to come on so I can’t tell if it is on.

evalutation amofit S
La première nuit où j'ai porté l'amofit, j'ai mal dormi, comme si mon corps évacuait des émotions engrammées dans le nerf vague. Je l'ai porté régulièrement, je me suis sentie bien, joyeuse, sereine, mes nuits calmes. Mais au bout d'un mois, je n'arrivais plus à dormir. Il me semble que j'ai fait une pollution aux ondes électromagnétiques. Donc électromagnéto sensibles, s'abstenir

Hi Florence,
Thank you for your recent purchase of amofit S. We are sorry to hear about your concerns regarding electromagnetic fields.
Firstly, electromagnetic signals generated from this device are far from the range of harmful electromagnetic fields.
In general, the frequency spectrum of electromagnetic waves known to be harmful is between 3 kHz and 300 GHz, while amofit S is less than 0.03 kHz. Additionally, 'amofit S' operates at a much lower level than the radiation standards of the governments in each country, so it is safe to wear the device all day (11.7-28.8 dBμV/m). The intensity of our device's electromagnetic field is also lower than that of the geomagnetic field and is similar to that of the innate magnetic field generated by the human body. (Intensity of the electromagnetic field generated by the device: 0.1 μT or less.) In addition, we have obtained certifications for the safety of the electromagnetic field generated by amofit S in accordance with safety standards in the United States (FCC), Europe (CE), and Korea (KC).
Therefore, you do not need to worry about harmful EMF at all while using this device. Instead, we think it is necessary to pay close attention to the effects of EMF of wireless mobile phones and everyday electronic devices that each of us is using.
For reference, no adverse health effects from low level, long-term exposure to radiofrequency or power frequency fields have been confirmed, but scientists are continuing their research in this area. In recent years, national authorities in different countries have conducted many measurements to investigate the level of electromagnetic fields in living environments. But none of these investigations has concluded that the field levels could result in adverse health effects.
However, according to a study in 2016, a report (on the effect of ultra high frequency mobile phone radiation using radio frequencies up to 300 MHz to 3GHZ on human health) describes the risk of mutation and sexual trauma and infertility in masculine sexual cells by mobile phone radiations.
Lastly, our first commercialized product, AMO+, was launched in South Korea in 2019 and we had over 15,000 users for AMO+. Then, we conducted two additional clinical trials and released an upgraded version, amofit S, in the global market in 2022. To date, amofit S has been shipped to and is used by over 14,000 users. In our clinical studies and user experiences over the past 6 years, there have not been any reports of negative effects due to the electromagnetic signal itself. We can tell you again with confidence that you do not need to worry about any harmful electromagnetic field by using amofit S.
Should you have any other questions or concerns, please do not hesitate to let us know. Thank you again.
