Abstract:
The realization of intelligent sensing involves high requirements on the number and the performance of flexible pressure sensors, Therefore, it is nessary to develop a simple, inexpensive, and scalable method for manufacturing the sensors with high sensitivity and relatively large scope. A flexible piezoresistive pressure sensor is developed based on the silver/carbon nanotubes-polydimethylsiloxane (Ag/CNTs-PDMS) composite prepared by the cube sugar template method and with the dip-drying process. The test result indicates that the thus developed sensor has a most high sensitivity of 0.718 kPa
-1, a wide working range (up to 40 kPa), a short response time of 1.14 s, as well as a good repeatability. Owing to its good sensing properties, this sensor has a potential application in the detection of pressure in real-time.
