Design and fabrication of A T.E.N.S. pain relief unit

In this paper, a T.E.N.S. (Transcutaneous Electrical Nerve Stimulation) pain relief unit is designed and fabricated. A low-frequency pulsed electromagnetic field (PEMF) of spike signals applied to ruptured bone, damaged soft tissues, pain and cancerous tumors have considerable healing effects. The effectiveness of PEMF for curing of pain and osteoarthritis is the focus of this article. Precise low frequency pulsed electromagnetic fields (PEMFs) produce definite cellular and biological effects, based on the amplitude, pulse width, pulse rate and wave shape. Here a pain relief unit is designed having spike waveform of varying amplitude ranging from 0 to 300 volt, frequency range between 30Hz and 130Hz and pulse duration of 1μsec.
