A high-performance magneto-mechano-triboelectric nanogenerator (MMTEG) was demonstrated by introducing accelerated water-soluble nano-bullet modified nanostructures to convert a gentle magnetic field into electric energy for powering an indoor wireless positioning system. NaCl salt nanoparticles were accelerated by an aerosol deposition (AD) process to collide on a perfluoroalkoxy (PFA) film with a high kinetic energy for the formation of a complicated nanomorphology on the triboelectric active surface. Under an alternating current (AC) magnetic field of 7 Oe, the MMTEG generated an open-circuit peak-to-peak voltage (V_pp) and a short-circuit current of 708 V and 277 μA, respectively. The harvesting device also presented a maximum peak power of 21.8 mW as well as a continuous AC output power of 4.8 mW (4.8 mJ per second). A self-powered indoor IoT positioning system was constructed by integrating the MMTEG, a power managing circuit, a storage element, and an IoT Bluetooth beacon. The electric energy from the MMTEG device enabled continuous operation of a beacon device, and we successfully confirmed the accurate location of the installed wireless positioning system, subsequently resulting in transmission of our indoor position to the main monitoring computer. Lastly, the MMTEG generated an open-circuit V_pp and a short-circuit current of 330 V and 23 μA, respectively, near a 60 Hz power cable connected to home appliances, which were large enough to turn on 108 blue light emitting diodes (LEDs).

由加速的水溶性纳米子弹驱动的高输出磁机械摩擦发电机，用于为无线室内定位系统提供动力†

通过引入加速的水溶性纳米子弹修饰的纳米结构，将柔和的磁场转换为电能，为室内无线定位系统供电，展示了一种高性能的磁-机电-摩擦纳米发电机（MMTEG）。NaCl盐纳米颗粒通过气溶胶沉积（AD）工艺加速，以高动能碰撞在全氟烷氧基（PFA）膜上，从而在摩擦电活性表面上形成复杂的纳米形态。在7 Oe的交流（AC）磁场下，MMTEG产生了开路峰峰值电压（V _pp）和短路电流分别为708 V和277μA。收割设备还提供了21.8 mW的最大峰值功率以及4.8 mW（每秒4.8 mJ）的连续AC输出功率。通过集成MMTEG，电源管理电路，存储元件和IoT蓝牙信标，构建了一个自供电的室内IoT定位系统。MMTEG设备产生的电能使信标设备得以连续运行，我们成功地确认了已安装的无线定位系统的准确位置，随后将室内位置传输到了主监控计算机。最后，MMTEG产生开路V _pp 连接到家用电器的60 Hz电力电缆附近的短路电流分别为330 V和23μA，该电缆的大小足以打开108个蓝色发光二极管（LED）。
