Thank you dear ericgibbs, we'll test it.
And any experience or idea about reading bio voltages from body?
I mean impedance matching, instrumentation amplifier feedback with left/right leg, and mor ...
mercy
OK
In our researches, we found that commercial products use a constant 11uA (micro Ampere) current source to measure the potential voltage between file clip and lip clip.
Now can anybody suggest a circuit to make such a small precision highly stable constant current?
Any idea is appreciated.
Dear friends,
I know this topic is for 10 years ago,
but one of my friends wants to design such a apex locator for his final college project
and he doesn't find any thing useful.
Can anyone give a schematic reference please?
Thanks in Advance
