Described as "the world's first non-skin contact wearable device which aims to improve overall human body performance and help people with anxiety, insomnia, and chronic disease related to problems in the vagus nerve," the Amofit S is the improved version of the AMO+, which was released in 2019, and starts at US$199.

With 725 Indiegogo backers and a total pledged amount of US$171,288, the amofit S wearable is now already shipping. This product comes as a direct successor to the first-generation AMO+, which was tested for the past two years in the South Korean market. During the tests, which included clinical trials as well, it has been proven that the technology used can address insomnia, stress, and anxiety, also helping to improve the health of patients that suffer from various neurological disorders related to the vagus nerve and the autonomic nervous system.

According to the aforementioned Indiegogo campaign page, the amofit S is the smallest device in its category currently available on the market. It has a 0.6-inch diameter and weighs only 0.03 pounds. The amofit S can be attached to the collar via the included clip or worn like a necklace. It features an 80 mAh battery with an autonomy of up to 9 hours and needs up to 1.5 hours to recharge. It sports two modes, namely calm and focus. The first one generates an electromagnetic signal that helps to improve sleep and correct the body's internal balance by increasing the vagal tone and activating the parasympathetic nervous system. The second mode improves memory and creativity by increasing the Alpha brain waves. The effective range, in both cases, is 9 inches, so there is no need to attach the device to the skin.

The clinical studies and the backers' reviews revealed that over 60 percent of the users were able to notice significant improvements in less than 3 days of use. In the first clinical trial, the positive effects lasted over 72 hours after just 2 hours of using the device.

Those interested can order the amofit S in light gray or dark gray. The current price tag reads US$199, which is 33 percent down from the US$299 MSRP. Family packs are also available for US$387 (a pair) and US$739 (two pairs).

Amofit S Uses Patented Neuromodulation Technology to Improve Sleep and Reduce Stress Level

Delivery status. ‘Amofit S’ units are being assembled and shipped in real time

February 21, 2022. Amo Lab launches an Indiegogo campaign for its newest innovation, ‘amofit S’, the world's first non-skin contact wearable device which aims to improve overall human body performance and help people with anxiety, insomnia, and chronic disease related to problems in the vagus nerve.

‘Amofit S’ is a long-awaited follow-up to the company's first-generation product, AMO+, which was released on a well-known Korean crowdfunding platform, 'Wadiz', in 2019. With over 2,249 supporters and overwhelmingly positive responses from the backers, the Amo Lab team has been committed to the mission of advancing the technology to ensure the ultimate combination of performance and safety.

“There are various chronic diseases that are difficult to be solved with modern medical technology. Among these, the ‘invisible’ diseases such as chronic stress, anxiety, and lack of sleep negatively affect and disrupt our immune system and increase the risk of developing or worsening the diseases,” says Min Kyu. “The amofit S provides an easy solution to the problems that are fundamentally difficult to solve in the modern healthcare system, such as insomnia, stress, and nervous disorders.”

Four main components of a healthy body and a clear mind include regular exercise, healthy diets, good sleep, and low-stress levels. Our innovation is going to drastically improve two of these factors ─ better sleep and lower stress — along with many additional benefits that fundamentally improve the human body.

How does amofit S work?

'amofit S' operates with the help of AMO Lab's proprietary neuromodulation technology, cVES (cervicothoracic vagus electromagnetic stimulation), which targets the vagus nerve in the human's autonomic nervous system. 

With a mild intensity similar to the innate magnetic field generated by the human body itself, the electromagnetic signal passes through the skin, muscles, and bones without any interference. It then is transmitted to the vagus nerve in the chest area. This signal regulates the vagal tone and activates the parasympathetic nervous system. 

The procedure reduces anxiety, stress, and sleep problems, boosts healthy aging, and restores the balance of the body. As a result of stimulating alpha brain waves and restoring internal balance through homeostasis, users will also notice major improvements in memory and creativity.

'amofit S' provides two healing modes.

  • CALM mode - Increase the vagal tone and activates the parasympathetic nervous system to improve sleep, stress, and anxiety and correct the body's internal balance, as well as help with chronic diseases related to problems in the vagus nerve and the autonomic nervous system. 

  • FOCUS mode - Enhances memory and creativity by promoting the generation of alpha brain waves and restores the internal balance through homeostatic autoregulation.

Approved by various testings 

To ensure the safety of the technology, ‘amofit S’ has undergone several tests including a clinical trial on HRV, conducted at KRISS (Korea Research Institute of Standards and Science). The experiment revealed a 275% increase in the activities of the parasympathetic nerves by analyzing EEG (Electroencephalography), ECG (Electrocardiogram), and melatonin hormone measurements.

“Heart rate variability (HRV) functions as a biomarker in health and disease. It is also the best biomarker to track longevity of the human. The initial goal of our team of scientists is to develop bioelectronic medicine for chronic pain with vagus nerve stimulation (VNS) technology,” adds Min Kyu, the CEO of the company. 

In addition, 'amofit S' has also been tested against the US FCC, European CE, and Korean KC directives and conforms to safety standards. (You can access our available certifications and scientific papers here).

AMO+ (the ancestor of Amofit S) is currently holding an excellent user score of 4,5/5 based on the experience of 2,249 backers.

Appearance and functionality 

Amofit S is the smallest device of its kind available on the market. Due to the miniature size and the neutral color variations (light grey/dark grey), it can be worn over clothing using a necklace string or by clipping the product to your collar without any inconvenience. In addition, a non-contact neurostimulation technology ensures that the device is also effective from a distance of up to 9 inches.

The device operates with the help of touch buttons. Press on the logo area for 3 seconds to turn on the device. A further press on the mode selection area will switch the modes from ‘Calm’ to ‘Focus’ and vice versa. Based on our clinical studies and the reviews from the backers, It will take only 3 days (30-minutes sessions each) to already experience noticeable benefits.


‘Amofit S’ is currently in its shipping stage and is available for backers on Indiegogo with a starting price of $199.

About the team

‘Amofit S’ has been brought to reality by a group of young scientists holding bachelor's degrees in biology, chemistry, and computer engineering. Initially formed in 2012 at the University of Illinois at Urbana-Champaign, the small group of researchers has eventually grown into a biotechnology company currently known as Amo Lab with branches in South Korea and the United States. 

The Amo Lab team completed the cVES technology in 2017 based on the rapid biomarker changes in HRV (heart rate variability) discovered in a clinical study back in 2013. To date, the company has developed more than 30 treatment protocols.

The scientific paper on the topic “Physiological evaluation of Non-invasive wearable vagus nerve stimulation device” has been conducted by the Amo Lab research team and published in “Springer Nature” in July 2019.
