Abstract
The present invention is directed to a sensor-enabled geosynthetic material for use in geosynthetic structures, a method of making the sensor-enabled geosynthetic material, and a method of measuring geometric strains of a geosynthetic product made from the sensor-enabled geosynthetic material. The sensor-enabled geosynthetic material includes a polymeric material and an electrically conductive filler. The polymeric material and an electrically conductive filler are combined to provide a sensor-enabled geosynthetic material. The sensor-enabled geosynthetic material having a predetermined concentration of the electrically conductive filler so as to provide the sensor-enabled geosynthetic material with an electrical conductivity and a strain sensitivity within the percolation region or slightly above it.
