Abstract:
A dimensionally stable sensor for monitoring termite activity, comprising:a dimensionally stable monitoring substrate having a first side and a second side, the monitoring substrate comprising a polymeric termite edible material, the polymeric termite edible material being resistant to dimensional expansion or contraction caused by changes in ambient humidity and/or temperature; and an electrically conductive circuit material affixed to or embedded in the first side of the monitoring substrate; the electrically conductive circuit material being breakable by termite activity; the electrically conductive circuit material forming a continuous electrical bridging circuit such that when termite activity breaks the electrically conductive circuit material, the continuous electrical bridging circuit is broken; the continuous electrical bridging circuit being resistant to breakage for an extended period of time from exposure to change in ambient humidity and/or temperature fluctuation such that the dimensionally stable sensor is less susceptible to false positive responses and/or false negative responses in monitoring termite activity.
