Recent Studies from Chonnam National University Add New Data to Scientific Instruments

June 6, 2014

By a News Reporter-Staff News Editor at Science Letter -- Research findings on Scientific Instruments are discussed in a new report. According to news reporting from Gwangju, South Korea, by NewsRx journalists, research stated, "In this study, an improvement in energy conversion efficiency has been reported, which is realized by using a double-clamped piezoelectric beam, based on uniaxial stretching strain. The buckling mechanism is applied to maximize axial stress in the double-clamped beam."

The news correspondents obtained a quote from the research from Chonnam National University, "The voltage generated by using the double-clamped piezoelectric beam is higher than that generated by using other conventional structures, such as bending cantilevers coated/sandwiched with piezoelectric film, which is proven both theoretically and experimentally. The power generation efficiency is enhanced by further optimizing the double-clamped structure."

According to the news reporters, the research concluded: "The optimized high-efficiency energy harvester utilizing double-clamped piezoelectric beams generates a peak output power of 80 ?W, under an acceleration of 0."
