Non-invasive ear nerve stimulation for healthy volunteers
This study tests whether a non-invasive device that stimulates a nerve in the ear can affect health. It is for healthy adults who are not taking medications (except birth control) and can avoid eating and exercise for 12 hours before two of the visits.

This study tests a small device that stimulates a nerve in your ear (not invasive, no needles) for different lengths of time to see how it affects your body. It is for healthy adults and does not involve any drug or surgery.
This trial tests how different electric stimulation settings on the ear (via a small device) affect healthy adults' nervous system functions. It's a research study, not a treatment, to help understand optimal stimulation parameters for future therapies.
This study is testing a device that stimulates a nerve in the ear (called the vagus nerve) using a gentle electrical pulse. It might help with certain conditions by affecting the brain and body, but the specific condition it aims to treat is not listed here.
This study tests whether a small device that gently stimulates a nerve in your ear can help reduce nausea. Researchers will enroll healthy adults to see if this non-drug approach is safe and effective.
