Significant Contributions to Technology development and Education
Carried out pioneering work on micro- machining and MEMS in the country and delivered several educative lectures in Engineering colleges and National Conferences bringing out the importance and technological impact of this field in the defence, industry and biomedical areas.
Designed and developed micro-machined silicon accelerometer for operation up to 15g. Presently, the production modifications of the device are being carried out at BEL, Bangalore.
As a part of the National Program on Smart Materials (NPSM), and as the Principal Investigator of the team, instrumental in the design and fabrication of piezoresistive micro-machined pressure sensors for differential pressures in the range 0 to 10 atmospheres. Details are enclosed in a pamphlet (PDF, 66KB) which was recently prepared for the Industry interactive meeting held at the Indian Institute of Science , Bangalore during March 19-20, 2004
Built an excellent state of the art laboratory in the Electrical Engineering Department of the IIT Madras for education, training students and for manpower development in the country in the Microelectronics and MEMS field.
Designed courses and experiments in the Microelectronics laboratory for teaching and educating the High speed device technology involving materials such as Gallium Arsenide and Indium Phosphide. Carried out research work and guided several research theses in this area
Presently, coordinating an Inter Disciplinary Research Project between Departments of Electrical Engineering, Mechanical Engineering , Chemical Engineering , Metallurgical and Materials Engineering , Applied Mechanics , Chemistry and Physics in the Indian Institute of Technology Madras in the MEMS area to carry out research and develop technologies relate to micro-pump and micro-fluidics, RF MEMS for switches and filters, micro structures for test and analysis, Biosensors and Bio-MEMS
Principal Investigator of a project on Design and fabrication of silicon Micro pump for drug delivery and drug dosage control for biomedical applications, at flow rates in the range 1 to 10 micro liters per minute. This is particularly being developed for injection of controlled dose of insulin to diabetic patients.
