Key Benefits

• Stimulates the vagus nerve for relaxation and focus.

• Promotes balanced autonomic nervous system activity.

• Enhances sleep quality and reduces stress levels.

• Features an ultra-light, wearable design for daily comfort.

amofit S uses advanced bioelectronic technology to stimulate the vagus nerve and promote balance within the autonomic nervous system. It delivers low-frequency electromagnetic signals that help the body manage stress, improve sleep quality, and enhance mental clarity. The device operates through AMO Lab’s proprietary cVES (cervicothoracic vagus electromagnetic stimulation) technology, which targets the vagus nerve in the chest using gentle electromagnetic waves similar to the body’s own natural signals.

The device features two modes—CALM and FOCUS—designed to regulate vagal tone and support specific needs. CALM mode helps ease stress and supports restful sleep by activating the parasympathetic nervous system. FOCUS mode promotes creativity and concentration by encouraging alpha brainwave activity.

Lightweight and compact, amofit S measures just 3.9 x 3.9 x 0.8 cm and weighs 14 g. Its necklace-style design allows easy, comfortable use throughout the day, providing an accessible way to maintain nervous system balance and mental wellbeing.

amofit S uses cVES (cervicothoracic vagus electromagnetic stimulation) technology to stimulate the vagus nerve through gentle, non-contact electromagnetic signals. This method directly targets the nerve pathways that influence neurotransmitters, inflammation, and metabolism, helping the body maintain balance without drugs or surgery. Unlike traditional stimulation therapies, cVES works within a nine-inch radius, offering deeper and broader effects than local treatments. The technology mirrors the body’s natural electromagnetic signals, restoring equilibrium in the most natural and safe way. By improving vagal tone and nervous system balance, it helps you experience calmer energy and better mental clarity.

amofit S was created by a team of scientists from the University of Illinois who discovered a way to improve heart rate variability using mild electromagnetic signals. Their breakthrough led to the founding of AMO Lab in 2016, a bioelectronics company based in the United States and South Korea. The team developed a non-contact vagus nerve stimulation device designed to restore balance in the autonomic nervous system and support better sleep, stress management, and overall wellbeing. Through this pioneering neurostimulation technology, amofit S helps you rest deeply, recover naturally, and feel more in tune with your body every day.

Wear the device for at least 30 minutes daily to support calmness and focus. For optimal results, use CALM or FOCUS mode for one session of approximately three hours each day. CALM mode may be used for up to two sessions per day, while FOCUS mode should not exceed one session per day. Attach the device to your collar using the clip or wear it as a necklace for comfortable, hands-free use.

Contraindications
