Abstract

In this manuscript, we reported two multi-functional units aiming at providing a promising monitoring platform applied in walking sticks for elderly and motion impaired people. One rotational unit equipped with an electromagnetic generator (EMG) and linear-to-rotary structure is proposed to harvest the ultra-low frequency linear motion of a walking stick and serve as the sustainable power supply for an Internet of Things (IoT) sensing system. And one hybridized unit further integrated with two self-powered triboelectric sensors to extract the motion features of the walking stick is designed to achieve multi-functional monitoring of users with deep learning technology. Promisingly, the walking stick equipped with proposed units shows a great potential of being an intelligent aid for motion-impaired users to help them live a life with adequate autonomy and safety.

用于自我可持续物联网传感和超低频能量收集的多功能混合单元

在这篇文章中，我们报道了两个多功能单元，旨在为老年人和运动障碍者提供一种有前途的手杖监测平台。提出了一种配备电磁发生器(EMG)和线性-旋转结构的旋转单元，用于收集手杖的超低频线性运动，并作为物联网(IoT)传感系统的可持续电源。设计了一个混合单元，进一步集成两个自供电摩擦电传感器，提取手杖的运动特征，利用深度学习技术实现对用户的多功能监控。有希望的是，配备了拟议单元的手杖显示出巨大的潜力，可以成为运动障碍用户的智能辅助工具，帮助他们过上足够自主和安全的生活。
