Triboelectric Energy harvester

Project: Development of Cost-effective Triboelectric Energy Harvester: Performance Enhancement and Systematic Experimental Study

Abstract: A comprehensive experimental study has been performed to develop the reliable cantilever structured TEH device prototypes and further performance enhancements by altering the surface and bulk profile of the PDMS polymer tribo-layer with the cost-effective fabrication process. A cost-effective experimental test set-up has been developed to test the vertical contact-separation mode triboelectric energy harvesting devices for the real-time measurements of input and output parameters with less than 2% uncertainty. A systematic experimental study of resistive load matching and extensive experimental parametric case study has been carried out to correlate the tapping frequency with force excreted by tapping and its effect on TEH performance for a low-frequency range (1Hz to 7Hz).

Biosensor

Project: Non-Destructive Real-Time Glucose Quantification Using 5-Turn eandered Signal Coplanar Sensor Integrated with Circular PDMS Cavity

Abstract:

The experimental demonstration in the prospective application of the novel label-free microwave-based Meandered Signal Coplanar Sensor (MSCS), for the non-destructive quantification of the glucose in aqueous solution, has been presented. The sensor has been designed by embedding 5-turn meander inductor in the signal conductor of a 50_ coplanar waveguide (CPW) transmission line, where the sensing area is configured with Polydimethylsiloxane (PDMS). Precursory modelling of the CPW transmission line and the meander inductor have been executed in MATLAB and further optimization has been carried out in 3D CST Microwave Studio Suite 2017 simulator. The experimentally measured magnitude and peak frequency for S11 and S21, respectively, showed good sensitivity of 18.42 dB/g/ml, 265.72 MHz/g/ml, 36.51 dB/g/ml and 1050 MHz/g/ml, respectively. The regression analysis with high linearity of 0.921, 0.944, 0.762, and 0.839, respectively, validated the correlation of the glucose concentration with the magnitude and peak frequency of the S-parameters.

Project:

Abstract: A real-time label-free microwave diagnostic approach using Co-Planar Waveguide (CPW) design has been demonstrated for glucose detection. This mechanism has tremendous potential for the biomedical applications. Here, glucose biosensor is implemented with 50Ω CPW transmission line, where the centre localized 3mm diameter of CPW transmission line has been used for the sensing. Glucose sensor is implemented utilizing low cost multilayer PCB and polymer Poly-Di-Methyl-Siloxane (PDMS) fabrication technology. CPW transmission line is fabricated on FR4 microwave laminate board. To confine the Analyte Under Test (AUT) on the sensing area, PDMS polymer cavity is configured in the centre of CPW transmission line. The electromagnetic interaction with the varying dielectric constant of Glucose: DI water solution results shift in S11 parameter, which is closely observed to use as the source of sensing. CPW based glucose sensor is experimentally measured for S11 parameter using VNA, with varying glucose concentration range from 0 mg/ml (only DI water) to 4 mg/ml with the interval of 1 mg/ml. The measured results showed good sensitivity of 108.4 MHz/mg/ml and high accuracy with good linear regression coefficient of 0.9979.

Design of microwave devices using Machine learning

Project: Prediction of design parameters of Microstrip Transmission Line using Machine Learning techniques.

An artificial neural network (ANN)-based prediction model  has been demonstrated to analyse microstrip transmission line (MTL) for the characteristic impedance, Z0. The ANN predictionmodel will overcome the time and effort  required to design MTL using costly radio frequency (RF) software tools. The ANN  model has been developed using feed forward back propagation (F-F B-P) algorithm with three hidden layers and optimized by gradient descent (GD) optimizer. ANN model has been developed on the dataset built using analytical formulation. The training, validation and test error obtained for the model are 7.197×10−5, 6.189×10−5 and 0.66, respectively, demonstrating high accuracy.

A warm welcome to the modified and updated website of the Centre for East Asian Studies. The East Asian region has been at the forefront of several path-breaking changes since 1970s beginning with the redefining the development architecture with its State-led development model besides emerging as a major region in the global politics and a key hub of the sophisticated technologies. The Centre is one of the thirteen Centres of the School of International Studies, Jawaharlal Nehru University, New Delhi that provides a holistic understanding of the region.

Initially, established as a Centre for Chinese and Japanese Studies, it subsequently grew to include Korean Studies as well. At present there are eight faculty members in the Centre. Several distinguished faculty who have now retired include the late Prof. Gargi Dutt, Prof. P.A.N. Murthy, Prof. G.P. Deshpande, Dr. Nranarayan Das, Prof. R.R. Krishnan and Prof. K.V. Kesavan. Besides, Dr. Madhu Bhalla served at the Centre in Chinese Studies Programme during 1994-2006. In addition, Ms. Kamlesh Jain and Dr. M. M. Kunju served the Centre as the Documentation Officers in Chinese and Japanese Studies respectively.

The academic curriculum covers both modern and contemporary facets of East Asia as each scholar specializes in an area of his/her interest in the region. The integrated course involves two semesters of classes at the M. Phil programme and a dissertation for the M. Phil and a thesis for Ph. D programme respectively. The central objective is to impart an interdisciplinary knowledge and understanding of history, foreign policy, government and politics, society and culture and political economy of the respective areas. Students can explore new and emerging themes such as East Asian regionalism, the evolving East Asian Community, the rise of China, resurgence of Japan and the prospects for reunification of the Korean peninsula. Additionally, the Centre lays great emphasis on the building of language skills. The background of scholars includes mostly from the social science disciplines; History, Political Science, Economics, Sociology, International Relations and language.

Several students of the centre have been recipients of prestigious research fellowships awarded by Japan Foundation, Mombusho (Ministry of Education, Government of Japan), Saburo Okita Memorial Fellowship, Nippon Foundation, Korea Foundation, Nehru Memorial Fellowship, and Fellowship from the Chinese and Taiwanese Governments. Besides, students from Japan receive fellowship from the Indian Council of Cultural Relations.
