Wafer-scale Fabrication of Cyclo-Phenylalanine Peptide Nanowire Based Triboelectric Energy Generator

초록

Recently, wearable devices are essential for internet of things (IOT) based technology. In this backgrounds, biocompatible devices are necessary for fully wearable systems. This study developed a wafer-scale fabrication method of cyclo-phenylalanine peptide (cyclo-FF) nanowire array by thermal evaporation. After then, triboelectric energy generators (TEG) was fabricated and the cyclo-FF nanowires were employed as triboelectric materials that stable and biocompatible. The output voltage and current of TEG were ~ 350 V and ~ 10 μA respectively with corona discharge surface treatment. Even though cyclo-FF were dipped into water and TBS buffer solution, it still worked like earlier devices. In conclusion, the cyclo-FF nanowire array were fabricated simply and employed as triboelectric materials of TEG which performed excellent output characteristics for future applications.
