Current research

A brief overview of our current research activities can be found at - https://www.youtube.com/watch?v=VnOTudCa4hA.

Some specific details are provided below.

i) Microfluidic sensors for detection of disease biomarkers in body fluids

The current focus is on the detection of biomarkers in sweat. Microfluidic wearable devices for the efficient collection of sweat are being worked upon, with an on-going work on a multi-analyte sensor array to detect some of the biomarkers. Designs are being investigated to enable detection with small sample volumes.

ii) Flexible thermal sensors

 Different gel-based materials have been developed which have shown good temperature sensitivities. The thermally assisted charge transport aspects are being investigated. Apart from utilization in applications as wearable electronics, other uses could be in packaging/storage of temperature sensitive materials like medicines, reagents, blood etc.

iii) Electrochemical strip-based sensors

Composites of metal nanoparticles as the sensing materials for detection analytes through electrochemical routes are being investigated.

iv) Room temperature flexible gas sensors

The room temperature gas sensing behavior of composites of organic semiconductors and inorganic oxides are being investigated. Aspects on the synthesis of the precursors, ink formulations, and printing are investigated to obtain printed sensors on flexible substrates. Insights gained though experiments on factors affecting the recognitions reactions and the accompanying charge transport, supported by simulations, help provide the knowledge needed to application specific sensors.
