Flexible Carbon Monoxide Sensor For Environmental Detection Of Small-Scale Robot
MICRO & NANO LETTERS(2020)
摘要
With the advancement and development of science and technology, the detection role of small-scale robot has become increasingly prominent, especially for environmental detection in hazardous situations such as explosion and fire. In this study, to realise the detection of carbon monoxide gas in hazardous locations, a flexible carbon monoxide sensor consisting of polyimide, interdigital electrode, and composite film is proposed and designed, which has the advantages of simple structure, high sensitivity, good flexibility, and low cost. For the interdigital electrode, the distance between the electrodes and the width of the electrode is both 50 mu m, and the sizes of the polyimide substrate and the electrode area are 1.5 x 4 cm(2) and 1 x 1 cm(2), respectively. The composite film is made by mixing single-walled carbon nanotubes and platinum powders. The test results show that the sensitivity of the sensor is 0.0201 Omega/ppm in the range of 0-100 ppm at room temperature with a linear fit of 94.63%.
