AI Article Synopsis
- The study focused on electrochemical sensors made from printed carbon nanotubes (CNT) on a PET substrate, assessing their mechanical stability through bending and tape tests.
- Two types of sensors were created—resistance-type (R-type) and comb-type (C-type)—and were tested with diluted NH droplets to evaluate their performance metrics.
- Results showed that the comb-type sensor outperformed the resistance-type in terms of response time, sensitivity, and detection limit, and the study further explored its effectiveness against 12 harmful substances.*
Article Abstract
We studied electrochemical sensors using printed carbon nanotubes (CNT) film on a polyethylene telephtalate (PET) substrate. The mechanical stability of the printed CNT film (PCF) was confirmed by using bending and Scotch tape tests. In order to determine the optimum sensor structure, a resistance-type PCF sensor (R-type PCF sensor) and a comb-type PCF sensor (C-type PCF sensor) were fabricated and compared using a diluted NH droplet with various concentrations. The magnitude of response, response time, sensitivity, linearity, and limit of detection (LOD) were compared, and it was concluded that C-type PCF sensor has superior performance. In addition, the feasibility of PCF electrochemical sensor was investigated using 12 kinds of hazardous and noxious substances (HNS). The detection mechanism and selectivity of the PCF sensor are discussed.
