Researchers from Yamagata University Detail Findings in General Science (Fully-printed high-performance organic thin-film transistors and circuitry on one-micron-thick polymer films)

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Science. According to news originating from Yamagata, Japan, by NewsRx correspondents, research stated, "Thin, ultra-flexible devices that can be manufactured in a process that covers a large area will be essential to realizing low-cost, wearable electronic applications including foldable displays and medical sensors. The printing technology will be instrumental in fabricating these novel electronic devices and circuits; however, attaining fully printed devices on ultra-flexible films in large areas has typically been a challenge."

Our news journalists obtained a quote from the research from Yamagata University, "Here we report on fully printed organic thin-film transistor devices and circuits fabricated on 1-mm-thick parylene-C films with high field-effect mobility (1.0 cm(2)V(-1)s(-1)) and fast operating speeds (about 1 ms) at low operating voltages. The devices were extremely light (2 gm (-2)) and exhibited excellent mechanical stability. The devices remained operational even under 50% compressive strain without significant changes in their performance."

According to the news editors, the research concluded: "These results represent significant progress in the fabrication of fully printed organic thin-film transistor devices and circuits for use in unobtrusive electronic applications such as wearable sensors."
