Abstract

In this paper, we report a 3D printed hybridized nanogenerator which can convert the in-plane arbitrary motions and vibrations into useful electrical energy. Also, it can detect in-plane arbitrary motions and vibrations effectively. The proposed device consists of a central magnet based hybridized electromagnetic (EMG) and triboelectric nanogenerator (TENG) and the repulsive force from central magnet drives the four side magnets for self-powered motion sensors (MS1, MS2, MS3 and MS4). The EMG and TENG generates the peak power of 18 mW at 193 $\Omega$ and 3.25 $\mu$ W at 10.5 M$\Omega$ load resistance, respectively. The proposed motion sensor is capable of sensing arbitrary motion in 3-axis directions. With the integration of motion sensing capability as well as energy harvesting on the same device, a complete self-powered sensor system has been successfully demonstrated.

基于全向面内磁斥力的自供电任意运动传感器及混合纳米发电机

在本文中，我们报道了一种3D打印的杂交纳米发电机，它可以将平面内的任意运动和振动转化为有用的电能。此外，它还能有效地检测平面内的任意运动和振动。该装置由一个基于中心磁体的混合电磁(EMG)和摩擦电纳米发电机(TENG)组成，中心磁体的排斥力驱动四个侧磁体用于自供电运动传感器(MS1, MS2, MS3和MS4)。EMG和TENG分别在193 $\Omega$和10.5 M $\Omega$负载电阻下产生18 mW和3.25 $\mu$ W的峰值功率。所提出的运动传感器能够在3轴方向上感知任意运动。在同一设备上集成了运动传感能力和能量收集功能，成功地演示了一个完整的自供电传感器系统。
