叠层废弃葡萄皮压电薄膜的制备和应用研究OA

This study utilized grape skins,an agricultural waste material,to prepare novel bio-based piezoelectric films.After composited with PEN-ITO conductive films,multilayer grape skin piezoelectric film sensors with a'sandwich'structure were fabricated,exhibiting stable voltage output under mechanical stress.The double-layer grape skin piezoelectric film sensor achieved the highest sensitivity(42 mV/N),representing a 133％increase compared to the single-layer sensor(18 mV/N)and a 100％increase compared to the triple-layer sensor(21 mV/N).Furthermore,the double-layer grape skin piezoelectric film sensor exhibited excellent linear correlation between voltage and cur-rent(R2＞0.976).For applications in human motion monitoring,micro-energy harvesting,and acoustic detection,the layered-structure flexible sensor demonstrated excellent adaptability.
