Feasibility study

Enlarged view: 3D printed prototype of an device für the human ear

We are looking for healthy participants to take part in a feasibility study looking at different prototypes of a novel brain stimulator. During this research study conducted by RELab, we aim to investigate the usability of different designs of electrode earpieces for non-invasive Vagus nerve stimulation (taVNS) in healthy individuals.

Your participation in this study would greatly contribute to the advancement of our medical device for non-invasive brain stimulation for conditions such as stroke rehabilitation. We believe that the results of this study will have important implications for a device which will ultimately improve physical and cognitive function in a range of clinical settings.

More information about the study:

Participation in the study takes 2 hours. During the study, you will be asked to:

put on different electrode earpiece designs undergo a stimulation calibration stage to determine the appropriate stimulation intensity
receive stimulation of the Vagus nerve
record your physiological responses via heart rate and pupil dilation
answer questionnaires about the electrodes and the stimulation

We will collect data on your physiological responses such as the pupil diameter, heart rate and galvanic skin response.

Ideal participation between 11.03.2024 and 22.03.2024.
