rate (SAR) is 0.135 W/kg, which is within the SAR limits
in the IEEE standards (the averaged SAR over 10g of tissue
should less than 2 W/kg) [37].
IX. Test of the HybridVNS
A. Test Setup and Procedure
We can not conduct a full closed-loop operation test of
the HybridVNS because the IVNS has not yet been approved
for implantation in humans. Thus, a simulation ex10

periment on the closed-loop operation of the HybridVNS
was fulfilled. Firstly, the WER recorded the EEG signals of
human subjects, and if a seizure onset was detected, the
WER send an instruction wirelessly to the IPG and turned
it on. Six patients that suffered from epilepsy at the Department
of Neurology of the Affiliated Hospital of Jiangsu
University were recruited and their EEG data were recorded.
The detailed information of each patient (such as
age, sex and number of years they suffered from RE) can
be found in Table II. The recruitment criteria was the participant
over the age of 18 years, recently
suffered seizure onsets more
than two times per month and they
need to stay in the hospital for medical
treating and monitoring. During
(or before) the seizure onsets, each
patient wore a WER and their scalp
EEG was recorded and monitored
by the TESD (Fig. 16).
Secondly, an acute rodent epilep34

model was established to formulate
the seizure onset of human subjects.
In the experiment, an adult
male Sprague-Dawley rat (200~300 g,
provided by Jiangsu University)
was fixed to the stereoscope. Next,
after injecting of 1.25 g/kg urethane
to the abdominal cavity of the rat
for anesthesia, a small incision was
made at the head skin above the
CA1 area (Fig. 17). In addition, two
recording electrodes (CBARC75,
produced by FHC, also used as
stimulating electrodes) were in
close contact with the head skin in
