Research Areas

BioMEMS is a rapidly advancing, inter-disciplinary research field for creation and development of new methods/systems to effectively process or manipulate biological materials with electronic devices and components. Giving a prior importance to the biomedical sensing research, an interdisciplinary R&D work at School of Medical Science and Technology, IIT Kharagpur has been initiated to promote MEMS and Biosensor activity that encompasses design, fabrication and engineering of biomedical & microfluidic devices for its electro-physiological characterisation. For the evaluation of electrical and physical properties of biomolecules and cells using suitable micro-fluidic devices, appropriate fabrication of polymeric coated bio-MEMS are being investigated and its utility are evaluated under different microscopic and electrical impedance study. The research also involves development of different BioMEMS transducers and related technologies for sensing various biomedical signals for precise and appropriate diagnostics and therapeutics. Microfabrication technology is being explored to develop various miniature MEMS devices for deployment of in-vivo and in-vitro detection of biomedical signals and its characterisation.

Presently, the following activities are being pursued:
  • Development of MEMS based flow sensor on flexible substrate - Realization of a polymer (PDMS) based cardiovascular shear stress/ flow sensor using micro fabrication techniques on catheter to monitor real-time blood flow for atherosclerosis diagnosis satisfying sensitivity, biocompatibility and reliability requirements. The major aim of this research is to develop catheter-based MEMS sensors to provide high spatial and temporal resolution for real-time monitoring in the vasculature.
    Separation and manipulation of cells on Microfluidic Platform by Dielectrophoresis - Realization of an integrated microfluidic device with planer electrodes for rapid and continuous separation of biological cells in mixed cell population with high selectivity using dielectrophoresis technique.
    MEMS based Biosensor for Electrophysiological characterization of cells – Electrical impedance spectroscopy (EIS) is used to study the electrochemical phenomena in cells and the toxicological effects in cells.
