a supporting material 34 may also be used to provide structural integrity composites of certain embodiments of the invention have also been tested at varying humidity and over extended periods of time and found to exhibit an insignificant amount of change in performance such composites have also been found to provide a recovery time after inducing an overloading current of within 5 10 seconds after the overloading condition was ceased although both the hydro gel and composites of the invention act as a parallel capacitor resistor the hydro gel has a dc resistance of about 500 ohms while a doped adhesive of the invention has a dc resistance of about 100k ohms or higher the hydro gel has a capacitance in both high u02dc 10 khz and low u02dc 200 hz frequency ranges in the microfarad range the doped adhesive of an embodiment of the invention has a more pronounced capacitance that varies with frequency effect from about 230 pico farads at 10 khz to about 1 microfarad at 200 hz the dielectric constant k must therefore be changing with frequency in fact at 10 khz it is discovered that k is about 10 and at 200 hz k is about 10 000 or above when the k is lower the resistance increases which requires that the pad impedance and matching impedance of the monitoring equipment must be increased in other embodiments the polymeric material may include various polymeric materials such as acrylic adhesives that may be distinguished by the relative composition of their monomers and by their molecular weights.
