GENERATION OF TENS ELECTROSTIMULATOR USING NE555 TIMER

Abstract

This work consists of the design and implementation of a TENS electrostimulator (Transcutaneous Electrical Nerve Stimulation), which generates its signal with an oscillator created from a NE555 Timer, in which, its shape and signal amplitude can be varied from potentiometers, in order to also modify the frequency at which it will work and which is connected to a power stage with a tip31C transistor, in addition to having its own power source, which connects directly to the alternating current at home, since it has its respective transformers and diode bridge to rectify the signal, also integrating voltage regulators to avoid noise and distortions of the signal, and thus be able to generate electrical impulses that can be used in the human body for therapeutic use. Obtaining an electrostimulator that generates an electrical impulse signal for the use of electrotherapy with a preliminary established frequency of 100Hz.
