This project aims to create a human vagus nerve stimulator by using mechanical vibration. Users
can stimulate the vagus nerve under different stimulation intensity by adjusting the frequency
through a variable resister and a 555 Timer IC. The project consists of two parts: hardware
implementation and experimental design. The hardware is basically the setup for the experiment.
Results were concluded based on the data analysis after a great number of experiment was done.
Therefore, the results have a high reliability and could be used for further development and
