Andrey Sushko
Finalist, 2012 Intel Science Talent Search
Andrey entered an engineering project in the Intel Science Talent Search in which he used the surface tension of water to turn the shaft of a tiny motor — only 7 mm in diameter. Working in his home, Andrey began by testing various materials to determine which one best-facilitated curvature of the water surface when an electrical current was applied. After choosing the hydrophobic coating that worked the best, he constructed a motor to translate that curvature into shaft rotation. The key feature of his work is that, unlike conventional motors, the efficiency of Andrey’s motor should, theoretically, increase with miniaturization. He believes his work may pave the way for micro-robotics and a range of other micro-mechanical devices.
