Indian Institute of Technology, Bombay
Guide: Prof. Upendra Bhandarkar
An improvement in the traditional cooking stove was achieved by fabricating a simple twisted tape assembly (costing about Rs. 65), which could be placed on it. This was done without making any changes to the cooking stove. The field-level tests resulted in reduction of firewood consumption by about 21%, soot accumulation by about 38% and the time of cooking by about 18.5% (Fig 2).
SRISTI Socially Relevant Technological Innovation
Cardiovascular diagnosis for rural healthcare
Sushanth Poojary, Pradip Gatkine, Saket Choudhary
Indian Institute of Technology, Bombay
Guide: Prof Santosh Noronha
Rural Public Health Centres in developing countries generally lack medical expertise and access to diagnostic devices for cardiovascular diseases. Commercially available arterial pulse analysers are costly and not portable. Arterial pulse analysis of radial and brachial artery can be used to observe an early indication, if any, of cardiovascular disease. The team has developed a low-cost portable arterial pulse analyser that records the pressure waves at radial and brachial arteries non-invasively using piezoelectric ceramic plate sensors. This analyser provides real-time display of arterial pulse waveforms during the test and the analysis of waveforms in a digitally storable format (Fig 3).

Using the emerging technique of Res-piratory Sound Analysis, a unique diagnostic mobile based app-lication (i-Treat) has been developed, which is capable of preliminary diagnosis of pneumonia. The application captures the respiratory sounds of the infant through the mobile’s microphone and checks for patterns in the respiratory sounds peculiar to pneumonia and the analysis of the same (Fig 4).
Laser-based fully computerised automated breast cancer and muscle screening system development
Samir Kumar Biswas
Indian Institute of Science, Bangalore
Guide: Prof. K Rajan
This is a simple low cost laser-based automatic optical imaging system for diagnosing breast cancer and imaging composite tissue. Optical encoder and MATLAB interface detect the position of source and detector. The software dynamically changes source-detector positions to irradiate the tissue surface and collects photon exit data from different tissue surface positions for the automated optical imaging. Ex vivo and in vivo imaging of composite animal tissues, and human muscle tissue have been undertaken using this automated optical imaging system. The retention and refraction of photon through a cancer cell is very different from a normal cell. This difference is used to detect cancer (Fig 5).

Technological Edge/Strategic Innovation
Injectable silk fibroin hydrogel for tissue engineering and drug delivery
Surojeet Das
Indian Institute of Technology, Guwahati
Guide: Dr. Biman B. Mandal
Injectable hydrogels have a potential advantage over various other biomaterial matrices due to their properties like minimal invasiveness, targeted delivery and ease of encapsulation of bioactive molecules and cells before gelation. Silk fibroin hydrogel has been fabricated by utilising Bombyx mori and Philosomia ricini silk (Fig 7).
Silk hydrogel when loaded with growth factors, cells or drugs could be injected directly in a minimally invasive manner into a defective site requiring a matrix for tissue regeneration or could be utilized for sustained release of drugs and bioactive molecules providing a safe alternative avoiding the complications of an open surgery. Moreover, the cost of fabrication of silk hydrogel is much less than the available options like collagen, hyaluronic acid based products and visco supplements.
Highly stable metallic nanoparticle-semiconductor hetero structures via click chemistry for photoelectro/ photocatalytic applications
Arun Prakash Upadhyay, Dilip Kumar Behara, Gyan Prakash Sharma
Indian Institute of Technology, Kanpur
Guide: Dr Sri Sivakumar
Semiconductors, as photocatalyst, play a central role in solar harvesting devices, and there have been many efforts to improve their performance including band gap tuning to increase photon absorption cross sections, adding sensitisers to enhance charge carrier lifetimes by decreasing electron-hole separation to improve surface redox reaction rates (Fig 8).
A generic “chemical” approach has been proposed that uses click chemistry for fabricating gold, titanium oxide and silicon dioxide nanoparticles on alkyne or azide modified Si, TiO, TiO2, stainless steel and glass substrates. The stability, ohmic properties, electro/photo electrochemical and photocatalytic properties of the interface have been demonstrated via photo electrochemical water splitting, methanol oxidation and photocatalytic degradation of Rhodamine B (RhB) dye. The proposed approach can be extended for large-scale fabrication of highly stable hetero structure materials centric electrochemical and photo electrocatalytic devices.
Biomimicked polymer surfaces exhibiting super-hydrophobic and anti-reflective properties
Srinadh Mattaparthi
Indian Institute of Technology, Hyderabad
Guide: Prof. Chandra Shekhar Sharma
The structure of seedpod, petal and leaf of Canna indica L. was biomimicked using various polymers and then studied for their wettability characteristics. The biomimicked polymer surfaces were found to exhibit superhydrophobicity. The superhydrophobic nature of the seedpod with high aspect ratio and hierarchical patterns having much larger surface area were not only preserved but also slightly improved in the RF gel replica (Fig 9).
The petal and leaf biomimicked polymer surfaces with multi-scale surface patterns were further studied for their antireflective properties. The biomimicked high aspect ratio micron features as found in Canna indica petal and leaf demonstrated near zero reflection for a wide range of wavelength and incidence angle of light. The fabrication of superhydrophobic as well as antireflective polymer surface using this low cost simple biomimicking technique opens possibilities of use in a variety of applications like solar cells, self-cleaning materials, microfluidics and energy storage devices.
Development and pilot testing of nano-sized TiO2 based Photocatalytic Oxidation technology for controlling
VOCs
Indramani Dhada, Pavan Kumar Nagar
Indian Institute of Technology, Kanpur
Guide: Prof. Mukesh Sharma
Volatile Organic Compounds (VOCs) are harmful air pollutants and are harmful to the skin, central nervous system, kidney and liver. The half-life of these VOCs in the atmosphere is about six years. So, it is necessary to find ways to reduce the concentration of these VOCs at the source as well as in the atmosphere. While much research is happening on TiO2 based Photocatalytic Oxidation (PCO) of VOCs, its commercial application has remained a challenge (Fig 10).
A Photocatalytic Oxidation (PCO) technology for industrial use for controlling VOCs at source and in situ ambient air using nano-semiconductor catalysts (TiO2) and ultraviolet (UV) radi-ation (external source and/or solar UV radiation) has been developed. The technology has achieved an overall efficiency of 61 and 77 per cent with one and two reactors (in series).
Microfluidic immunosensor
Ramchander Chepyala, Satyendra Kumar, Narendra Kumar, Bhanu Prakash
Indian Institute of Technology, Kanpur
Guide: Prof. Siddhartha Panda
Much research has been ongoing to develop diagnostic biochips that can be used to efficiently analyse low amount of sample in a short period of time. The available devices do not have many integrated sensors, and have issues like cross-contamination, unstable temperature of the substrate or reagents and non-reusability of the microchips (Fig 11).
The present invention relates to a lab-on-a-chip (LOC) device and provides an Electrolyte Insulator Semiconductor (EIS) based Microfluidic Immunosensor, which measures the changes in surface potential between the electrolyte (desired analyte) and the sensing insulator by a shift in capacitance–voltage (C–V) curves. This shift is a direct representation of sensitivity of the device from which quantification of a particular disease marker (present in the sample) can be obtained. This device provides a reliable detection of different biomarkers, specifically in cancer, and for other diseases.
‘Paper-and-pencil’ micro fluidic device for Point-of-Care diagnostics
Ranabir Dey, Shantimoy Kar
Indian Institute of Technology, Kharagpur
Guide: Prof. Suman Chakraborty
Rapid Diagnostic Test (RDT) kits are not commonly available for many diseases prevalent in developing countries like ours. Even for such kits, the test procedures can be labour and time-intensive, requiring expert supervision all the time. Using innovative fabrication methodologies, the team from IIT Kharagpur has developed a miniaturised and multiplexable device with a high throughput rate. Unlike other alternatives, this does not require an elaborate infrastructure and trained on-field pathologists. Most RDT kits available are qualitative in nature. However, the device makes use of colorimetric quantitative detection techniques (Fig 12).

mission
Pijus Kundu
Indian Institute of Technology, Kharagpur
Guides: Prof. T. K. Bhattacharyya and Prof. Soumen Das
Micro and nano-satellites for future space missions require miniature propulsion systems for precise and accurate control of spacecraft. The micro-fabrication technology of MEMS (micro-electromechanical systems) has been successfully employed to batch produce micro-propulsion systems or micro-thrusters capable of producing extremely small thrusts in the range of micronewton to millinewton. Combining silicon micromachining technology with a simple low-cost nanotechnology synthesis process, Vaporising Liquid Microthruster (VLM) and catalyst- based chemical microthruster have been developed. The thrusters achieve a high thrust force and specific impulse with minimum electrical power (Fig 13).
