●Primary responsibilities include taking care of the development of gas sensor, synthesis, testing, pattern generation & recognition using ANN.

●Developing system for analyzing the sensor array’s response.

Project Title: Development of Nanostructured Metal Oxide Gas Sensor for Detecting Chemical Surface Agents

Client: Defense Research & Development Establishment, Gwalior.

Successfully Executed following mini projects based on AT89C51 Microcontroller

●LCD & keyboard interfacing: In this project I’ve learned to interface a 4x4 keyboard and an LCD with AT89C51. The program to interface keypad with controller was written in assembly language.

●Temperature Controller: The controller was made to measure and control the temperature of the furnace for using AT89C51 microcontroller. The sensor feeds the controller with signal, where it is converted to digital and processed. The measured temperature is shown on an LCD, and the microcontroller thus turns on/off the furnace so as to maintain at the required temperature.

●CO Gas detector: The detector was made using a CO (Carbon Monoxide) sensor TGS2442, manufactured by Figaro. The microcontroller receives the signal from the sensor, checks the response to the environment and if the response matches to that of CO it triggers a buzzer. The sensor possesses high sensitivity/selectivity to CO also very low power consumption, thus making it an ideal device for handheld CO detectors.

Jan’12 – June’12

Title: Implementation of an Integrated Artificial Neural Network trained with Back Propagation Algorithm.

Description: Artificial Neural Network (ANN) is a mathematical model that is inspired by the structure and/or functional aspects of biological neural networks. A neural network consists of an interconnected group of artificial neurons, and it processes information using a connectionist approach to computation. The thesis discusses the motivations behind the development of ANNs and describes the basic biological neuron and the artificial computational model. It presents ASIC (semi-custom) and FPGA implementation of the network for solving the XOR problem using Fixed-point format (FXP) for representing real numbers. It concludes with a comparison of results obtained for ASIC and FPGA.

Tools Used: Cadence IUS, RTL Compiler (rc), Encounter, Xilinx ISIM, XST, PlanAhead, XPower Analyzer.

Project 1: Modelling of artificial neural network using VHDL.

Aug’11 – Oct’11

Description: Modelled a 3:3:3 neural network using ring architecture. This model has fixed weights, i.e., it does not employ any learning algorithm for weight updation.

Project 2: Implementing automatic car parking control on Xilinx Virtex II pro board.

Nov’10 – Dec’10

Description: The module counts the number of cars entering the parking, automatically assigns slot based on availability as a new car enters, it also update the availability status as cars exit. If all parking slots are occupied, it doesn’t allow more cars by closing the barrier.

Project 3: Implementation Of Signal Code Modulator & Demodulator (using MATLAB).

Jan’08 – June’08

Description: Signal Code Modulation utilizes the property of digital modulation and analog modulations simultaneously to reduce the error probability (analog transmission) and the quantization error (digital transmission).


2 Research Papers published in the proceedings of IWPSD(International Workshop on the Physics of Semiconductor Devices) – 2009:

●Detection of NO2 at room temperature: The sensing of NOx cannot be done at room temperature using undoped SnO2, thus limiting the operability on battery and thus the portability of the sensing system. The gas sensing properties of doped and undoped SnO2/MWCNT (multiwalled carbon nanotube) composites (prepared by sol gel technique) were found to be improved in both temperature as well as time.

●Sensor Response of Nb Doped SnO2 Thick Films by Screen Printing Technique: Addition of Niobium oxide to SnO2 thick film sensors was studied for morphological, structural and sensing property changes. Electrical measurements were performed in the presence of Acetonitrile, a simulating gas for a warfare agent HCN, in order to evaluate sensor properties. Nb-doped tin oxide powder was prepared by hydrolysis and co-precipitation method. Addition of niobium species into the tin oxide matrix resulted in a decrease in the grain size, found using X-ray diffraction (XRD) and electron microscopy. An improvement in response was observed on niobium addition that can be attributed to the decrease in tin oxide powder.

1 Research Paper published in the proceedings of IJWBME(India- Japan Workshop On Biomolecular Electronics & Organic nanotechnology for Environment Preservation) – 2009

●Effect of Vanadium and Molybdenum oxide addition on tin oxide thin films for chemical warfare gas sensors: The effect of molybdenum and vanadium on SnO2 increases the response for DMMP (Dimethyl Methylphosphonate), sarin (a nerve gas) simulant. Also complete recovery was observed for the same, which is not possible with undoped SnO2 films.
