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 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
