Personalised vagus nerve stimulator. Measures heart rate and breath rate. AI powered.
SONA is a wearable vagus nerve stimulation device that combines neuroscience with adaptive AI technology to deliver personalized nervous system regulation. The ear worn device reads the user's breathing rate and heart rate to assess their state of arousal, then delivers precisely-timed electrical stimulation pulses synchronized with the user's breathing and heartbeat. The system learns over time to optimize stimulation dosage based on individual vagal sensitivity and physiological responses, targeting outcomes like improved HRV, deeper sleep, and reduced stress within the first month of use. The technology represents a shift from one-size-fits-all VNS approaches to truly personalized, biofeedback-driven protocols that respect individual nervous system variation.
