Hi,
Needed in study on galvanic current response, 0.3 to 1.1v (max), 0.1 to 3µA (max)
The terminology of "Galvanic current response" is the one described in the study.
Note that this is not a "GSR" study (observation on skin inductance/resistance), but on response elicited directly by µA and nA.
No references has been given nor examples of such a circuit, only preliminary studies and hypothesis on mechanisms.
The only requirements are portability and most of all for the circuit to be lightweight (taking into account the enclosure).
I have found examples of galvanic current "machines" but not with values similar to the study (3v to 5v)
The only informations on this type of circuit i have found is a question posted on another forum: How to generate 50µA of DC across dynamic resistance (2kohm - 20kohm)
(i don't know if i can share the link)
Constant current is needed for the electrodes (as deviations/increases are defined as not suitable, i did not find any constant regulator diodes for this project which would have been easier)
The button cells are the ideal choice in term of portability, and in regards to the specificity of the study.
If anyone has any ideas or suggestions, i would really appreciate any help.
