Introduction: Making Galvanic Skin Response Finger Electrodes

Picture of Making Galvanic Skin Response Finger Electrodes

Galvanic Skin Response or GSR is a physiological effect used in Biofeedback and Lie Detectors. I've developed an Android App that turns a smartphone into a GSR sensor. However, it requires making special finger electrodes to use. This video shows the process of making them from an Audio/Video cable and some Velcro. More information about Galvanic Skin Response and the program can be found on my website: http://www.extremenxt.com/gsr.htm .

Step 1: ​All of the Instructions Are in This YouTube Video.

The cable used in the video is a Philmore 42-3546.

The application doesn't reflect GSR in my case. It shows the level about 0.025 when nothing is attached to electrodes and 0.023 when they are attached to skin.

Who did make it?

You probably need the resistor as described in the link. Without it the program will not work.

The application is not working for me...:S

the ​code please to get the galvanic skin response value in the serial monitor

gaspery hay , you can upload videos of advanced video and could you please tell me how to work after connecting the cable to the phone . I really like the tools that you create. Thank you

can't find the video

The video is Step 1. Just click the triangle for it to play.

Strangely, the application does not have the option to play

gasperi (author)gal-x-e2014-09-22

The app calibrates for about 15 seconds then starts recording. I'm not sure why you don't think it is working.
