【摘要】：可穿戴电子设备正在迅速走进人们的日常生活,但是它的高速发展也带来了永续供电的问题。为了解决这个问题,先前的研究者提出了捕获人体热能、光能、环境中的振动能来为电子设备提供可持续的电压,然而其效果并不佳。除了上述的几种方法,捕获人体运动并将其转换为电能的方法,能够为可穿戴电子设备提供相对稳定可靠、功率较高的电源,更加适合用于解决可穿戴电子设备永续供电的问题。本文提出了几种基于人体足部、躯干和膝关节的能量捕获器,利用这些能量捕获器来捕获人体不同部位的运动并转换为电能,为电子设备供电。在设计能量捕获器之前,我们首先研究了正常步行时人体足部、躯干和膝关节的运动模式,然后根据它的运动模式建立了三个不同部位运动的数学模型。基于人体运动模型,我们分别设计了两种位于足部的嵌入式能量捕获器、三种位于躯干的背包式能量捕获器和一种可穿戴式的膝关节能量捕获器。为了提高能量捕获器的功率输出,还采用放大器、齿轮组等机构。与此同时,能量捕获器和人体之间的耦合也是设计的重点,因此还采用了可穿戴式的设计。此外,为了便于为电子设备供电,还针对能量捕获器设计了特定的电路。基于人体运动的数学模型,建立了各个能量捕获器的动力学模型,用于预测它的性能。通过动力学模型可以得到能量捕获器的理论功率输出和效率。为了验证理论模型,加工制造了各个能量捕获器的原型样机,并测试了它们的性能。实验结果表明,足部能量捕获器、躯干式能量捕获器和膝关节能量捕获器的最大输出功率为1W、7W和5.8W,可以为可穿戴式电子设备提供具有实用水平的电源。
[Abstract]:Wearable electronic equipment is rapidly entering people's daily life, but its rapid development has also brought about the problem of sustainable power supply. In order to solve this problem, previous researchers have proposed to capture human heat energy, light energy, vibration energy in the environment to provide sustainable voltage for electronic devices, but the effect is not good. In addition to the above methods, the method of capture human motion and convert it into electric energy can provide relatively stable, reliable and high power supply for wearable electronic devices. It is more suitable for solving the problem of sustainable power supply for wearable electronic devices. In this paper, several energy catchers based on human feet, torso and knee joint are proposed, which are used to capture the motion of different parts of the human body and convert it into electric energy, so as to power the electronic equipment. Before designing the energy catcher, we first study the motion modes of the foot, trunk and knee joint of the human body during normal walking, and then establish the mathematical models of the motion of three different parts according to its motion mode. Based on the human motion model, we design two kinds of embedded energy trap located in the foot, three kinds of backpack energy trap located in the trunk and a wearable knee joint energy trap. In order to improve the power output of the energy catcher, amplifiers, gear sets and other mechanisms are also used. At the same time, the coupling between energy catcher and human body is also the focus of the design, so the wearable design is also adopted. In addition, in order to facilitate the power supply of electronic equipment, a specific circuit is designed for the energy catcher. Based on the mathematical model of human motion, the dynamic models of each energy catcher are established to predict its performance. The theoretical power output and efficiency of the energy catcher can be obtained by dynamic model. In order to verify the theoretical model, the prototypes of each energy catcher are manufactured and their performance is tested. The experimental results show that the maximum output power of foot energy catcher, trunk energy catcher and knee joint energy catcher is 1W, 7W and 5.8W, which can provide practical power supply for wearable electronic equipment.
