| Summary: | The apparatus which could be measured both contact and rubber resistance was made. Contact resistance between bare metals and rubber was studied. The metal were brass, gold, silver and platinum. Contact resistivity, as the way to characterize contact, was also evaluated its possibility.
Contact resistance was independent from type of metals. Contact resistivity could be used to
characterize a contact, but current density should be specified.
Contact resistance measured from this apparatus was reasonable, but an error in rubber resistance was appeared. This could be caused by high contact resistance of the needles which were used as voltage probes and position of needles. |
