2-channel defence Transcutaneous Electrical Stem Stimulator (DTES)

During the battle war, the usage of analgesic is considered to be the fast solution for pain relief. However, frequent usage without the risk of health damage is impossible. Therefore we developed the Transcutaneous Electrical Stem Stimulator device (DTES) that can operate based on the pulse generator circuit used to generate electric current in pulse form and later to be delivered to the pain area. This device is equipped with a digital timer so that the duration of treatment can be set by the user. An electric current is passed through the skin in between electrodes to stimulate the nerve where the pain is located. The passing electric current will inhibit the delivering of pain message to arrive at the brain thus user will not feel any pain at the affected area. The stimulation also will increase the production of endorphin, a natural pain killer inside human body to overcome the sensation of pain. The measured frequency and pulse duration were 6.519 KHz and 153.4μs represented there were 6519 cycle in a single second. Since the estimated frequency and pulse duration were 6.667 KHz and 150 μs respectively, the differences were 0.148 KHz and 3.4μs or 2.2% and 2.3% which are considered small and acceptable. The stimulated current is relatively small thereby it will not cause harmful effects to the user.
