Abstract

This work reports a high-performance and highly sensitive self-sustained arbitrary motion sensing system (SS-AMSS) by integrating energy harvesting and self-powered sensing on a novel 3D printed geometry. SS-AMSS consists of a spherical magnet rolling inside the hollow ellipsoid surrounded with six planar spiral coils for scavenging energy from multi-direction and four triboelectric nanogenerators (TENGs) are integrated for arbitrary motion detection. Unlike traditional TENGs that require external stimuli for periodic contact-separation, the custom fabricated PDMS/FeSiCr ferroelectric film acts as an actuating layer, thus simplifying the TENG operation. The electromagnetic generator can deliver a peak power of 187 mW at 275 Ω matching load under 6 Hz frequency. The self-powered sensors have excellent motion sensitivities for detecting various motion parameters along with linear (X, Y, and Z-axis) and rotational (pitch, roll, and yaw axis) conditions. Finally, the capability of SS-AMSS as a complete wireless self-powered motion sensing system has been demonstrated.

自维持任意运动传感系统在无线自主控制中的应用

这项工作报告了一种高性能和高灵敏度的自持续任意运动传感系统(SS-AMSS)，该系统通过在新型3D打印几何形状上集成能量收集和自供电传感。SS-AMSS由一个在空心椭球内滚动的球形磁体和六个平面螺旋线圈组成，用于从多个方向清除能量，并集成了四个摩擦电纳米发电机(TENGs)用于任意运动检测。与传统的需要外部刺激进行周期性接触分离的TENG不同，定制制造的PDMS/FeSiCr铁电薄膜作为致动层，从而简化了TENG的操作。该电磁发电机在275 Ω匹配负载下，在6hz频率下可提供187mw的峰值功率。自供电传感器具有出色的运动灵敏度，可检测各种运动参数以及线性(X, Y和z轴)和旋转(俯仰，滚转和偏航轴)条件。最后，演示了SS-AMSS作为一个完整的无线自供电运动传感系统的能力。
