Bi3.15Nd0.85Ti3O12单晶

Nowadays, wearable and flexible nanogenerators are of great importance for portable personal electronics. A flexible piezoelectric energy harvester (f-PEH) based on Bi\u003csub\u003e3.15\u003c/sub\u003eNd\u003csub\u003e0.85\u003c/sub\u003eTi\u003csub\u003e3\u003c/sub\u003eO\u003csub\u003e12\u003c/sub\u003e single crystalline nanoplates (BNdT NPs) and polydimethylsiloxane (PDMS) elastomeric polymer was fabricated, and high piezoelectric energy harvesting performance was achieved. The piezoelectric output performance is highly dependent on the mass ratio of the BNdT NPs in the PDMS matrix.

如今，可穿戴、灵活的纳米发电机对于便携式个人电子具有重要意义。基于Bi3.15 Nd0.85 Ti3O12单晶纳米片( BNdT NPs )和聚二甲基硅氧烷( PDMS )弹性体聚合物制备了柔性压电俘能器( f-PEH )，获得了较高的压电俘能性能。压电输出性能高度依赖于PDMS基体中BNdT NPs的质量比。采用12.5wt % BNdT NPs制备的f-PEH在2.7 Hz、6.5 N的敲击模式下，最高输出电压为10 V，峰峰短路电流为1μA，功率为1.92μW，无需储能过程，可发光4个商用发光二极管。f-PEHs可用于收获日常生活能量，在收获鼠标点击或脚踩的机械能时产生2 ~ 6 V的电压。这些结果证明了基于无铅BNdT NPs的f-PEHs在可穿戴电子供电方面的潜在应用。
