Outline of Final Research Achievements

We have proposed a novel flexible sensor in which microwire-embedded β-phase poly(vinylidene fluoride) (PVDF) films are utilized. The polarization of PVDF was controlled by using thiol-modified gold surfaces that we developed in this study. We succeeded in detecting the pressure changes of the sensor in one-dimensional direction or two-dimensional plane, in accordance with a spatial resolution of 200 micrometers. Our proposed sensors would be very useful for practical realization of various wearable devices such as tactile sensors and sphygmometers.

Academic Significance and Societal Importance of the Research Achievements

本研究の溶液塗布法とチオール修飾による配向分極制御によって,高感度な一次元および二次元圧力マッピングセンサの作製が,非常に簡便な低温・溶液一貫プロセスによって実現可能となる。そのため,本研究はフレキシブル圧力センサや触覚センサの全く新しい方式を提案するものであり,新規性および産業上の活用性いずれの観点からも非常に重要である。特に,医療機器や検査装置への応用が可能であり,医療介護分野への大きな貢献が期待できる。
