Solid state water vapor sensor for robotics applications

Abstract

Preliminary results are presented on a solid-state water vapor sensor which is being considered for applications in robotics. The surface conductivity response produced by physical adsorption of water vapor on a glass surface used as the detection principle. A specific, sensitive, reversible conductivity response is observed at water vapor concentrations higher than 40% RH (relative humidity).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
