Abstract

This work discusses the use of Force Sensing Resistor (FSR) technology for Homeland Security applications. One area of particular focus is the optimization of wipe sampling of surfaces to facilitate enhanced trace contraband collection. Another focus area is the development of prototype sampling wands and other wand modifications that increase the reliability of wipe sampling by registering the placement of the collected sample properly on the wipe and providing visual feedback to the user that appropriate force is being applied to the surface. This paper outlines how an array-based FSR can be used to visualize contact area and pressure during swipe sampling, and how FSRs are being used to describe the relationship between sample collection and force. Also discussed is the integration of FSRs directly into sampling wands for screener training purposes, and new prototype sampling wands that fit in the palm of the hand.
