Abstract: Focuses on the fabrication of hydrogen sensors and hydrogen-activated switches from arrays of mesoscopic palladium wires. Preparation of palladium mesowire arrays by electrodeposition onto graphite surfaces; Impact of exposure to hydrogen gas on array resistance; Involvement of sensor response in the closing of nanoscopic gaps or break junctions in wire.
