Since 2016, he worked as a consultant for several companies on design of ultrasonic transducers using MATLAB models which he wrote from basic equations and with experimental validations. Number of unique concepts were created, where new matching layer using mass-spring model which is polymer-metal layers replacing traditional quarter wavelength layer leading to low cost production, multilayer absorber replacing traditional powder/binder, internal matching layer inside of protection metal layer enhancing sensitivity and bandwidth, multi-hole matching layer for air-gas transducers and super directivity of audio generation from air ultrasonic wave.
Learn More800 MATLAB programs are available which are to predict performance of piezo-transducers, sensors, composite or monolithic piezo-material parameters, PVDF or PVDFTrFE copolymer transducers, near field to far field acoustic directivity, electrical matching network and cable effect for ultrasonic transducers, multilayer flexural beam sensors for PVDF and PZT, cylindrical PVDF film for ultrasonic air transducers, etc. All the programs were wrote from basic theories, and as a result, calculated dependency provided detailed features of designs. In this way many ideas on new design concepts on transducers and sensors were created, and 57 US patents were granted, all of which are related or based on new concepts
Learn MoreHe owns a small laboratory and measurement equipment are available for experimental services. The equipment are impedance analyzer, network analyzer, precision LCR meter, pulse generator, function generators, variable gain/bandwidth amplifier, calibrated microphone, calibrated accelerometer and also fabrication machines, tools, piezoelectric materials (PZT, 1-3 composite, LiNbO3, PVDF, PVDF/PTrFE) are available, all of which are served for customized experimental investigations depending on customer's need.
Learn MoreWhile working for production companies, he achieved numerous inventions and publications in addition to solve design problems and support productions. He will continue to invent new concepts depending on required feature of new devices.
