摘要

多功能压电纳米发电机（PENG）在开发军事、医疗保健和工业领域的智能传感技术方面具有巨大潜力。在此，我们介绍了利用直流/射频磁控溅射技术在柔性镍基底上制造的基于 0.67Pb (Mg1/3Nb2/3)O3-0.33PbTiO3 (PMN-PT) / Ni50Mn35In15 (Ni-Mn-In) 的压电纳米发电机从机械和磁场刺激中高效采集能量的情况。通过使用各种砝码、手指敲击、弯曲和磁场施加 0.12 至 0.61 N 的力，对该器件的性能进行了评估。在施加 0.61 N 的力和手指敲击的情况下，该装置产生的最大开路电压（Voc）分别为 9.3 V 和 6 V。相应的短路电流（Isc）分别为 1.33 µA（0.61 N）和 0.9 µA（手指敲击）。在弯曲角度为 120° 时，器件显示出 10.6 V 的最大 Voc 和 1.51 µA 的 Isc。此外，在 0 Oe 至 500 Oe 的直流磁场下，Voc 和 Isc 分别从 0 mV 和 0 nA 增加到 240 mV 和 35 nA。所制造的器件功率密度为 2.7 µW/cm2，机械稳定性高达 2500 次循环。此外，绿色、红色、黄色和白色的发光二极管均已点亮。所制造的 PENG 对机械和磁刺激的接受能力突出表明了它在触觉传感、可穿戴电子设备、人机界面和生物医学设备等领域的潜力。

Harnessing the Mechanical and Magnetic Energy with PMN-PT/Ni-Mn-In-based Flexible Piezoelectric Nanogenerator

Multifunctional piezoelectric nanogenerators (PENG) hold significant potential in developing smart sensing technologies for the military, healthcare, and industrial sectors. Here, we present the efficient energy harvesting from mechanical and magnetic stimuli in 0.67Pb (Mg_1/3Nb_2/3)O₃-0.33PbTiO₃ (PMN-PT) / Ni₅₀Mn₃₅In₁₅ (Ni-Mn-In)-based PENG fabricated on a flexible nickel substrate using the DC/RF magnetron sputtering technique. The performance of the device has been assessed by imparting forces in the range of 0.12 to 0.61 N using various weights, finger tapping, bending, and magnetic fields. The device generates the maximum open circuit voltage (V_oc) of 9.3 V and 6 V with 0.61 N of force and finger tapping, respectively. The corresponding short circuit current (I_sc) has been obtained as 1.33 µA (0.61 N) and 0.9 µA (finger tapping). The device shows a maximum V_oc of 10.6 V and I_sc of 1.51 µA at the bending angle of 120^°. Furthermore, the V_oc and I_sc have increased from 0 mV and 0 nA to 240 mV and 35 nA under the presence of 0 Oe to 500 Oe of DC magnetic field, respectively. The fabricated device exhibited a power density of 2.7 µW/cm² with a high mechanical stability of 2500 cycles. Additionally, LEDs of green, red, yellow, and white color have been illuminated. The receptiveness of the fabricated PENG towards mechanical and magnetic stimuli highlights its potential in areas such as tactile sensing, wearable electronics, human-machine interfaces, and biomedical devices.
