This is a copy of the paper from this same author describing in detail the electrode that he made for ear stimulation.  But it has a lot of other information about the theory and applications of using transcutaneous auricular vagal nerve stimulation for various conditions.Usichenko tavns electrode et al.

“Vagal nerve stimulation (VNS) is recommended by the Food and
Drug Administration as an adjunctive therapy for epilepsy and
medication-resistant major depression [1]. VNS is promising as
a potential treatment for sleep and anxiety disorders, cognitive
deficits of the Alzheimer’s disease and chronic pain [2,3]. The
invasive VNS approach, using implanted battery-powered generators,
has several disadvantages: it requires repeated surgical intervention
for the implantation of the stimulator and electrodes,
battery replacements or a dysfunction of the electronic equipment
[4]. An alternative method of transcutaneous vagal nerve
stimulation, recently shown to produce a mood enhancing effect in
healthy volunteers [5] and antinociceptive effects in patients with
chronic pelvic pain [6], is based on anatomical data on cutaneous
representation of the vagal nerve. The auricular branch of the vagal
nerve supplies the external acoustic meatus and the concha auricle
[7]. Experimental data suggest that cutaneous stimuli of this region
are transported via the auricular branch of the vagal nerve into the
medulla oblongata and to the nuclei tractus solitarii [8], whereas
the stimulation of peripheral regions of the auricle (helix) is mainly
transmitted to the spinal ganglia of the cervical nerves [9].”
