Sona is an AI-powered vagus nerve stimulator designed to address stress and burnout.

Spearheaded by Jane Ollis, a former NHS leader in the UK, and a team of neuroscientists and engineers, the ear-worn device uses adaptive AI to deliver personalised nervous system support, to help users stay calm, focused and resilient.

“I saw people leaving hospital with treatment plans for their condition, but nothing for the stress, fear and isolation they’d face at home,” says Ollis. “It wasn’t right and it stayed with me,” she says.

Sona uses breath-synced pulses to target the vagus nerve and routines can be enhanced with sounds, breathwork or VR. It measures heart rate variability (HRV) in real time and tailors stimulation to the current state of the user’s nervous system.
