Abstract
The method of making a flexible elastic conductive material for strain sensor and resistance applications using rubbing-in technology is shown. The thin rubber or any conductive material (substrates) is fixed at strained condition on the solid plate, by rubbing-in technology. Nanopowder of nanomaterials (organic semiconductors, carbon nanotubes, copper doped tin oxide, manganese doped tin oxide) at room temperature are embedded into the rubber conductive material to make built-in structure of conductive flexible elastic substrates that can be used for strain sensors, gages and resistance applications. The resultant product showed good sensitivity, stability and reliability during and after the rubbing-in operation.
