Experiment Purpose: Using a standard ohmmeter measure various body fluids or their close equivalents. This will give an indication or relative resistance values of the body fluids encountered in E-Stim and E-Play Theory:
All materials in nature have an electrical resistance. Admittedly some are neither linear nor constant. We have seen this to be particularly true of ionic solutions. But using a standard measuring instrument like an ohmmeter for a given resistance scale the resistance measured should be time invariant once any ionic transport anomalies settle down. Besides what is desired here is a relative ranking of values. Such data is not known to be available from other sources.
Experimental Setup: The experimental setup is an easy one. Samples are collected in insulated containers, measured either volumetrically or by weight, and then the resistance is measured by ohm meter.
Equipment Used:
Experimental Procedure: Collect the sample in an insulated container and measure its volume or weight. Then with the ohm meter set to the Rx1Kohm scale, insert the probes at the opposite sides of the container and measure the resistance. Also note if the readings display any ionic transport anomalies. Record the data. Discard the sample and clean the containers.
For the animal fat measurement, first render the animal fat from the body pieces in a microwave oven. Once the fat is rendered, decant it into a measuring container to separate it from the solids. Measure the temperature of the sample and the resistance. Then allow the sample to cool to 100 deg F (approximating body temperature) and measure the resistance again.

Interpretation of Experimental Results: As demonstrated in the Field Mapping experiment, measurement of conductive fluids--and particularly ionic conductive fluids--exhibit a resistance that is dependent on the voltage applied. As long as that impressed voltage remains constant the resistance will maintain a steady state value. When low voltages are impressed on conductive fluids, the resistance tends to be higher than that measured at higher voltages. This phenomenon is again observed here.
With this voltage dependant resistance phenomenon acknowledged, the value of these measurements is still retained since the voltage impressed on the fluid by the ohm meter circuit is the same order of magnitude as that seen by a TENS Unit as used in E-Stim and E-Play.
In comparison then it can be seen that such fluids as urine and blood exhibit relatively lower resistances than semen or saliva. Animal fat can for all practical purposed be considered an insulator.
These measured values may now give designers some information when they build E-Stim and E-Play devices. At least now there are some published values for bodily fluids that one may encounter during such activity.
It should be remembered, however, that these measurements are steady-state, DC values. While this may also be the resistive component of the complex impedance offered to AC voltages of the same magnitude, there have not yet been similar measurements made of the imaginary components of these impedances. It is speculated at this time that the resistance component will be the dominating one of such an impedance, but designers should conduct their own measurements if their device is impedance dependant.
