Dr. N. Raghu, is Currently Working as Scientist -F at C-MET Thrissur.
He took his Ph.D. from I.I.Sc. in the area of electronic ceramic materials and did his post doc. research at Penn. State university U.S.A.
His group mainly concentrates in the area of Multilayer ceramic devices including electronic packaging and Piezo ceramic actuators. His group has developed various piezo ceramic actuators such as piezoelectric multilayer actuators, electrostrictive multilayer actuators, Flextensional actuators, Twin amplified micro actuator, Bimorph, unimorph, multilayer bender actuators etc.
His group has developed a piezo ceramic composition that sinters at 900 oC. Also crystallizable glass + ceramic compositions for LTCC applications have been developed.
Currently his group is working on oriented grain growth of PMN-PT ceramics through tape casting process and is also working on u-LTCC materials for MW packaging applications.
He had served as a member of the Naval Research Board (Materials).
