FIG. 1.

(Color online) (a) Illustration of configuration used for electrochemical deposition of Pd nanoparticles on the surfaces of SWNTs. (b) Geometry of a flexible hydrogen sensor on PET substrate with the use of modified SWNTs. The illustration was intentionally twisted in order to highlight mechanical flexibility of the sensor.

FIG. 3.

(Color online) Performance characterization of a sensor with channel length of and width of for sensing hydrogen molecules in air at room temperature. (a) Variation of resistance as a function of time when the sensor was repeatedly exposed to hydrogen in air and to pure air. (b) Response curves of the sensor to hydrogen with different concentrations: 100, 200, 500, 1000, 2000, 5000, and (from left to right). (c) Dependence of sensitivity and response time of the sensor on the concentration of hydrogen.

FIG. 4.

(Color online) Bending and fatigue tests over a hydrogen sensor when it was exposed to hydrogen in air. The inset presents the optical image of the sensor with curved geometry mounted on a probe holder.
