The main aim of the lab is to design and develop nanostructured materials to fabricate sensing devices and systems for measuring chemical species for different applications. The sensing materials are selected based on the desirable characteristics such as high sensitivity, low response and recovery times, high stability (thermal, chemical). The nanostructured of suitable pore morphologies of metal oxide/porous silicon are prepared using solution method such as sol-gel and chemical anodization. Detection electronics circuits for digital interfacing of the device to microcontroller for further signal conditioning are designed and developed. Efforts are also made to utilize softcomputing techniques such as Artificial Neural Network, Fuzzy logic and Neurofuzzy techniques to address some of the issues of the sensor. The lab is well equipped with modern facilities funded by the research projects from the Department of Atomic Energy (DAE) and Department of Science and Technology (DST). Experimental facilities have been created to work in the area of thin film /thick film nano structured sensor. A robust experimental set up has been developed to calibrate and test the sensors fabricated in the lab. The lab has successfully developed sensors such as (1) Capacitive type (2) Resistive type (3)Surface acoustic wave (SAW)-impedance type (4) Single chip thin film LC sensor. These sensors are used to measure moisture from parts per million (ppmV) to percentage relative humidity (%RH). Sensor Array has been fabricated for e-nose application. Low ppm moisture sensor can be used to fulfill the special needs of trace moisture measurement in different industries. LC sensors will be useful for RFID (Radio Frequency Identification Tag) application for monitoring the humidity of sealed package.
