Piezoresistive materials can change their resistivity with respect to the applied pressure. Therefore, piezoresistive materials are used in the development of pressure sensors. This project focuses on developing MWCNT/rubber composites as piezoresistive materials, which could use for monitoring real-time pressure. For instance real-time monitoring of the terrain that an automobile is going on, quality of gasket, the assembling faults associated with aircraft body panels etc. Ongoing studies focus on developing both active material as well as digital algorithms for capturing piezoresistive behaviors of the developed composites. Further studies are to be conducted on building a prototype 2D pressure sensor that can monitor the real-time pressure variation using a mobile device via Bluetooth or Wi-Fi technology.
