Lego GSR Sensor

This image was lost some time after publication, but you can still view it here.

This simple Galvanic Skin Response (or lie detector, in layman's terms) is made out of Lego motor wire and aluminum foil. It determines the electrical resistance of your fingers by measuring how relaxed and dry your fingers are.

I was inspired by talks by Mindfest panelists Karen Wilkinson and Mike Petrich who talked about using this type of sensor. I've also found out that the Media Lab at MIT has a program called the Affective Computing Research Project that also uses this sensor.


So you re saying that if I go to MIT I get to play with Legos? Sign me up!
