Growing zinc oxide (ZnO) nanowires (NWs) on yarns promotes smart sensing and creates opportunities for new applications. ZnO NWs sensing performance is influenced by its dimensions, which can be tailored by controlling the growth parameters. In this study, we investigated the effect of the growth parameters (time, temperature, and precursor concentration ratio) on the NWs’ morphology, dimensions, and piezoelectric performance. Our results showed that ZnO NWs produced with 6 and 9 h had long nanowires; however, they mainly got tangled with the nanowires on the adjacent fibers and peeled-off the fiber surface. Growth at a 1:1 precursor concentration ratio for 9 h produced the same nanowires’ length (~3 μm) as growth at a 3:1 precursor concentration ratio for 3 h. Among all of the studied growth conditions, ZnO NWs produced with a 3:1 precursor concentration ratio at 90 °C for 3 h showed uniform dimensions and stable electrical charge output.

纱线上生长的氧化锌（ZnO）纳米线（NW）促进了智能感应，并为新的应用创造了机会。ZnO NWs的传感性能受其尺寸的影响，可以通过控制生长参数对其进行定制。在这项研究中，我们研究了生长参数（时间，温度和前体浓度比）对NWs的形态，尺寸和压电性能的影响。我们的结果表明，在6h和9h时产生的ZnO NW具有较长的纳米线。但是，它们主要与相邻纤维上的纳米线缠结在一起，并剥落了纤维表面。以1：1前驱体浓度比生长9 h产生的纳米线长度（〜3μm）与以3：1前驱体浓度比生长3 h相同。在所有研究的生长条件中，ZnO NW的生成比例为3：
