Some Present Research (Ongoing)

Biomedical Electronics:

a) Development of suitable biomedical signal acquisition system for remote measurement and analysis of Heart sound

Heart sound is one of the primary ways of detecting many diseases. The Stethoscope is an acoustic medical device for listening to internal sounds in human body which is known, in medical terms it is called auscultation. Heart sound auscultation is one of the most basic ways to assess the state of the cardiac function. The research is on progress to develop suitable and wearable biomedical signal acquisition system for heart sound, which can be detected remotely through wireless system and can be analyzed for diseases with machine intelligence.

b) Development of wireless wearable biomedical signal acquisition system for remote measurement and analysis of ECG signal

Wearable physiological monitoring system consists of an array of sensors embedded into the fabric of the wearer to continuously monitor different physiological parameters and transmit wirelessly to a remote monitoring station. At the remote monitoring station, the data is correlated to study the overall health status of the wearer. The use of physiological sensors with miniaturized electronics to condition, process, digitizes and wireless transmission integrated into the single module. These sensors are strategically placed at various locations on the vest. Number of sensors integrated into the fabric form a network (Personal Area Network) and interacts with the human system to acquire and transmit the physiological data to a wearable data acquisition system. The wearable data acquisition hardware collects the data from various sensors and transmits the processed data to the remote monitoring station. The present research involves design development and fabrication of wearable ECG signal acquisition system for remote measurement and analysis using machine intelligence.

c) Non-invasive Blood glucose measurement

The Raman spectroscopy is used to measure the concentration of many important constituents (analytes) in serum and whole blood samples at physiological concentration in vitro across a multi-patient data set. A near-infrared (830-nm) diode laser generates Raman spectra that contain superposition of Raman signals from different analytes. Calibrations for glucose, cholesterol, urea, and other analytes are developed by use of partial least-squares cross validation. The research interest is to develop indigenous non-invasive Blood glucose measuring instrument for human use.

Geron Technology

(Assistive Technology for elderly people)

New developments in assistive technology are likely to make an important contribution to the care of elderly people in institutions and at home. Video‐monitoring, remote health monitoring, electronic sensors and equipment such as fall detectors, door monitors, bed alerts, pressure mats and smoke and heat alarms can improve older people's safety, security and ability to cope at home. Care at home is often preferable to patients and is usually less expensive for care providers than institutional alternatives. The research interest is to develop some assistive technology to give physical and mental support to the elderly people.

Sensor Technology

Multifunction, Multi parameter and multi array sensor development Sensor data mining and fusion

The research interest is to find out cross sensitivity of different sensor for separating the sensor data for multi parameters using sensor data mining and fusion.
