Current Research:
Dr Tan’s research expertise can be summed up as Acoustical Artifacts (AA). It is in the broadest sense all things about acoustics research activities; acoustics generation, piezoelectricity in gaming and mobile technology, renewable energy harvesting using vibration, bio-acoustics for mosquito larvae control (see here), active noise control using directional sound, and more recently ultrasonic propulsion (see here).
A couple of years ago Dr Tan worked on a cool, bizarre technology at the Massachusetts Institute of Technology (MIT) - a novel electro-mechanical underwater propulsion robot, called Huygens, installed with ultrasonic thrusters (UST) in place of conventional blade propellers. Unlike rotary propulsors, UST produces an acousto-fluidic jet of water from specialised transducers which its resultant “backthrust” is exploited for underwater propulsion or maneuvering purposes.
