Electronic Muscle Stimulation Circuit Switching IR2155 MC34063

Electronic muscle training, muscle stimulation devices were once very popular, the biggest reason is the affordable price I shared a different muscle stimulation circuit made with pic 16f84 before, this circuit is the same as logic, there are more or less differences control integrated circuits mc34063 and ir2155 electronic muscle training circuit diagram , pcb, panel drawings and winding information of the coil used in the circuit.

It consists of a boost converter and a switched oscillator stage. There are Mode, Rate, Level and Pulse Width controls.

Testing has shown that TENS is an effective and safe way to manage chronic and acute pain with virtually no side effects. Chronic pain conditions that can be alleviated with TENS include arthritis, lumbago, neck and back pain, postpathic neuralgia, and sciatica. Acute pain conditions such as fractures, muscle aches, post-operative pain and tennis elbow can also be managed with the TENS unit.

A TENS unit provides electrical stimulation of the painful area using electrodes attached to your skin. It may cause a tingling sensation in the area where the pads are attached. It is not known how TENS reduces pain. Some suggest that the nerves stop sending signals to the brain, thereby relieving pain. Alternatively, the stimulation can cause the body to produce natural pain-relieving substances called endorphins.

Whatever the cause, a TENS unit can provide pain relief for many people with minimal side effects. It does not provide a cure for the underlying cause of the pain, but it has great benefit as the amount of pain medication can be significantly reduced.

Features of the TENS Muscle Stimulator

Portable
Adjustable voltage level
Adjustable heart rate
Adjustable pulse width
Intermittent or continuous output

Caution: Note that the TENS unit should not be used if you have a pacemaker. The TENS unit should also not be used if the cause of the pain has not been determined or if you are pregnant. When using the TENS unit, do not attach the electrodes anywhere on the front of the neck and keep the TENS unit out of the reach of children.
