SCR explained   

   

This is an explanation how the Mindfield eSense App measures and calculates the SCR (Skin 
Conductance Response) for the eSense Skin Response. 

 

Overview 

 

The whole process of detecting and calculating the SCR is a cycle of four steps: 

1.

 

Listening state  

2.

 

Determining if the signal raise is really a SCR  

3.

 

Gathering and calculating SCR and listening asynchronously for SCR recovery phase   

4.

 

Initiate recovery phase and end of fluctuation
