【摘要】：可穿戴電子設(shè)備正在迅速走進(jìn)人們的日常生活,但是它的高速發(fā)展也帶來了永續(xù)供電的問題。為了解決這個問題,先前的研究者提出了捕獲人體熱能、光能、環(huán)境中的振動能來為電子設(shè)備提供可持續(xù)的電壓,然而其效果并不佳。除了上述的幾種方法,捕獲人體運(yùn)動并將其轉(zhuǎn)換為電能的方法,能夠為可穿戴電子設(shè)備提供相對穩(wěn)定可靠、功率較高的電源,更加適合用于解決可穿戴電子設(shè)備永續(xù)供電的問題。本文提出了幾種基于人體足部、軀干和膝關(guān)節(jié)的能量捕獲器,利用這些能量捕獲器來捕獲人體不同部位的運(yùn)動并轉(zhuǎn)換為電能,為電子設(shè)備供電。在設(shè)計能量捕獲器之前,我們首先研究了正常步行時人體足部、軀干和膝關(guān)節(jié)的運(yùn)動模式,然后根據(jù)它的運(yùn)動模式建立了三個不同部位運(yùn)動的數(shù)學(xué)模型。基于人體運(yùn)動模型,我們分別設(shè)計了兩種位于足部的嵌入式能量捕獲器、三種位于軀干的背包式能量捕獲器和一種可穿戴式的膝關(guān)節(jié)能量捕獲器。為了提高能量捕獲器的功率輸出,還采用放大器、齒輪組等機(jī)構(gòu)。與此同時,能量捕獲器和人體之間的耦合也是設(shè)計的重點,因此還采用了可穿戴式的設(shè)計。此外,為了便于為電子設(shè)備供電,還針對能量捕獲器設(shè)計了特定的電路�；谌梭w運(yùn)動的數(shù)學(xué)模型,建立了各個能量捕獲器的動力學(xué)模型,用于預(yù)測它的性能。通過動力學(xué)模型可以得到能量捕獲器的理論功率輸出和效率。為了驗證理論模型,加工制造了各個能量捕獲器的原型樣機(jī),并測試了它們的性能。實驗結(jié)果表明,足部能量捕獲器、軀干式能量捕獲器和膝關(guān)節(jié)能量捕獲器的最大輸出功率為1W、7W和5.8W,可以為可穿戴式電子設(shè)備提供具有實用水平的電源。
[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.
