Validation testing of components in high voltage Lithium battery systems for hybrid and electric vehicles; operating test equipments, interpreting results and preparing reports; experience in a collaborative work environments; experience of taking initiatives and being able to work with no supervision; creating and inputting test scripts for computer controlled automation of tests

Processed piezoelectric films and fabricated prototype acoustic sensors with conducting polymer electrodes having sensitivity close to commercial metal-electrode sensors

Studied processing-structure-property-reliability of PVDF and blends

Developed PVDF/blend films for higher voltage applications, which have lower leakage current and higher linearity, breakdown strength, applied voltage and energy density at higher thickness than commercial ones

Achieved 50% higher characteristic breakdown strength in these films than in commercial counterparts

Obtained 17% further increase in energy density over the previous PVDF films via polymer blending

Developed a new blend system with 25% higher energy density and with a characteristic breakdown strength at 30 µm that is 16.3% higher than that of a commercial high-dielectric-strength copolymer film at 10 µm

Developed a capacitor designing optimization and dielectric material evaluation/tailoring technique incorporating Weibull statistics, applicable to self-healing metalized film capacitors with single section winding. Established correlation between device performance, operating conditions and dielectric material properties

Modeled & simulated, using finite element method/boundary element method (FEM/BEM), distribution of electric field strength, energy and power loss density and enhancement factors at different applied field frequency in composites with either permittivity or conductivity-graded particles
