Galvanic Skin Resistance

Model No. DL 3155BIO8

At The Passage Of An Electrical Current, The Skin Shows A Resistance That Is Normally Within The 100 Kohm To 1 Mohm Range.
Such Resistance Decreases During Periods Of Emotional Stress.
The Changes Of The Resistance Are Particularly Significant On The Palm Of The Hands And On The Plant Of The Feet.
Moreover, The Surface Of The Skin Shows An Electrical Potential, That Can Reach Up To 50Mv And That Can Equally Be Influenced By Emotional States.

Theoretical Topics:
– Galvanic Resistance Of The Skin

– The Electric Characteristic Of The Skin
– Behaviour Of The Human Body At The Passage Of An Electric Current
– Different Types Of Measurements
– Measurement Of The Resistance And Of The Potential
– Visual And Audio Signaling

Circuit Blocks:
– Variation Of The Resistance In Direct Current Of The Skin With Relation To Humidity
– Recording Of The Changes Of The Galvanic Resistance Of The Skin Due To Emotional Or Physical Stimuli
– Typical Circuit That Is Used In The Monitoring Of The Gsr
