However, no appropriate GSR signal was seen on scope unlike the above Truth wristband circuits by Sean Montgomery.  Further development may likely would have resulted in working Wheatstone bridge-based circuit however, time did not allow given and working circuit of a different type was already acheived.

The Cornell EDA project was based on this GSR sensor for MRI machine monitoring.  The link on the Cornell EDA page is broken but it is still  
The Cornell EDA project was based on this GSR sensor for MRI machine monitoring by Minn State Univ.  This project used a Wheatstone bridge and an instrumentation amp IC.  The link on the Cornell EDA page is broken but it is still available via the wayback machine at:

Note the circuit using a wheatstone bridge and amplifier is also referred to as a bridge transducer amplifier like in the TI INA114 datasheet on page 12: http://focus.ti.com/lit/ds/symlink/ina114.pdf
