Finalizing The circuit

Finalizing The circuit

As for the final circuit, I had to reconstructed as a back up for presentation day.
It takes about 5 days to make this circuit on the breadboard functioning.
The picture below shows the waveform that resulted from the output electrode.

Then, the electrode will be measured by using clamp meter to check whether the electrode is giving the correct value or not. The maximum value that can be accepted by human body is 10mA.

The picture above show how the clamp meter works. The value that been displayed by clamp meter is 0.01A and it is equal to the required value which is 10mA.




The output consists of two electrodes that will attach on the skin and the picture below shows how the attachment of electrode on the skin.

Prototype of Electronic Muscle Stimulation is as below which the circuit will covered by a black casing. On the side of the casing consist of two switches (on/off), knob for minimizing or maximize the resistance to get a different frequency and pulse duration and also the wire of electrode.

As for this circuit, I managed to find the suitable current transformer that suit for this circuit. It is small transformer with 230V to 12V, 100mA.
