This cranial electrotherapy stimulator is a medical treatment that makes use of electrical energy to treat anxiety, depression and insomnia. It is a therapeutic tool to help heal the body, which primarily uses an electrical current to stimulate nerves and muscles through the skin. This device uses a few components such as 555 timer, decade counter and the TE connectivity’s slide switch and trimmer. This TE connectivity components offer high-performance designed to withstand extreme shock, vibration, temperature and altitude.
The circuit generates an adjustable current that flows through the clips that are placed on the earlobes. The waveform of this device is 400 milliseconds positive pulse followed by a negative one of the same duration, then a pause of 1.2 seconds. The main frequency is 0.5 Hz and doubles the pulse every 2 seconds. This specialized electrical impulse achieves a state of relaxation.
Electrotherapy stimulator is a simple device that can be easily constructed by electronics enthusiasts. It only needs a few components that are readily available in the market. This device can be applied to variety of treatments that include chronic pain and other medical conditions such as headaches and gout. See also some designs running on 9V.
