人体能为未来的科技提供能量吗？
科学家认为这是可能的。
马萨诸塞大学阿默斯特分校的研究 人员
发现人体可以用来收集废能
然后可用于为未来科技提供能量。
研究人员表示，人体可以用于6G，
也就是下一代无线通信技术。
大家好，欢迎来到 BusinessPhil。
在今天的视频中，我们将探讨6G技术 如何
把人体作为能量来源。
但在继续本视频之前，
别忘了订阅本频道，
并点击小铃铛以获取更多精彩内容。
现在，让我们开始本期视频吧。
尽管全球城市和农村地区仍在部署5 G，
工程师们已经在研发6G网络。
VLC使用光源发送数据，
是有望使6G远超5G的有前景技术之一 。
6G的未来承诺数据速率将快上千倍，
且延迟仅为5G的十分之一。
很快，不是吗？
随着6G的来临，
预计会有更多设备和传感器上线，
带来物联网时代的新阶段，
预计将从当前的5G开始。
6G将实现更快通信速度的原因是
VLC的发展——一种无线光纤网络。
那么究竟什么是可见光通信（VLC）？
可见光通信在最基本的层面上，
是一种利用LED发出的光来传输数据 的无线方式。
提供类似于 Wi-Fi 的联网、移动、高速通信，
因此衍生出“LeFi”这一术语。
这确实令人兴奋。
它可以作为独立的解决方案使用。
也可以作为射频或蜂窝网络通信的 补充。
该技术的理念是以极高速度对 LED 进行开关，
在纳秒级时间内、以极高频率切换。
可见光谱比射频频谱大一万倍，
换句话说，它的频谱范围远超射频。
因此可见光通信（VLC）被视为弥补射 频带宽限制的一种方式。
业界已实现了非常高的数据传输速 率，
这使其具有竞争力。
尽管信号无法穿透墙壁或其他障碍 物，
但无需直接视线，
只要光能从其他表面反射即可。
LED灯必须点亮才能发送信号，
但亮度可以调得非常低。
如果可见光通信成为现实，
它在传输数据方面会比Wi-Fi更出色，
因为它不会引起电磁干扰。
可见光通信是如何工作的？
可见光通信在很大程度上类似于无 线电传输，
在发送信息时，
不同的是，它用LED发出的光而不是无 线电波来传输。
信息与计算机科学教授，
马萨诸塞大学阿默斯特分校的Jichan g，
说在VLC阵列中，
单个LED每秒可以开关一百万次。
由于LED灯被用于我们所有的建筑物 中，
企业、街道和汽车也使用LED灯，
我们已经具备使用这项技术所需的 基础设施。
此外，任何带摄像头的设备，
例如笔记本电脑、平板电脑或智能手 机，
可以作为接收器，使这项技术发挥作 用。
这些LED还会泄漏能量
以侧信道射频或无线电波的形式。
这种能量可用于为可见光通信（VLC） 设备供电。
科学家们计划如何利用射频泄漏？
Xiong和他的同事着手制造一种天线
能够拾取这种能量。
他们用缠成线圈的铜线制作了天线。
然后对这些天线进行了测试
以查看它们能收集到多少能量。
研究人员发现，天线可以拾取更多能 量
当它与另一件物体连接时，
无论线圈的粗细如何
或铜线缠绕的圈数。
研究人员让天线接触诸如木材、
钢材、墙壁、平板电脑、手机，
甚至连笔记本电脑也被用来测试能 收集到多少能量。
研究团队发现，收集到的能量
在使用电子设备时会增加，
但当线圈与人体接触时，收集到的能 量最多。
总之，6G技术的未来令人惊叹，
并将改变我们对能源的看法。
人体将成为一种能量来源，
这意味着我们可能会看到一个
人们比以往任何时候都更加互联的 世界。
这项技术仍处于早期阶段，
但显然它有潜力
彻底改变我们的生活和工作方式。
我们很想听听大家的想法，
请在下方评论区告诉我们对这项新 技术的看法。

Original transcript (English)
Could the human body be used to power technologies of the future? Scientists think that is possible. Researchers at the University of Massachusetts Amherst have found that the human body could be used to collect waste energy that could then be used to power the technology of the future.
The researchers said that the human body could be used for 6G, which is the next generation of wireless communication. Hello, and welcome to BusinessPhil. In today's video, we will look at how 6G technology will use the human body as a source of energy.
But before we continue with the video, don't forget to subscribe to the channel and click the bell to get more amazing content. Now, let's get this video started. While 5G is still being set up in cities and rural areas around the world,
engineers are already working on 6G networks. VLC, which uses light sources to send data, is one of the promising technologies that could push 6G well past 5G. The future of 6G promises data rates up to a thousand times faster and a tenth of the latency of 5G.
That's fast, don't you think? With 6G on the horizon, an even larger number of devices and sensors are expected to go online, bringing a new phase of the Internet of Things era that is anticipated to start with the current 5G.
The reason why 6G will have faster communication speeds is the development of VLC, a kind of wireless fiber optic network. So what exactly is visible light communication or VLC? Visible light communication is, at its most basic, a wireless method that uses the light emitted by LEDs
to deliver networked, mobile, high-speed communication similar to Wi-Fi, leading to the term LeFi. Now that's something to be excited about. It can be used as a standalone solution or as a supplement to radio frequency or cellular network communication.
The idea behind the technology is to turn LEDs on and off very quickly, within nanoseconds, at a very high frequency. As the visible light spectrum is 10,000 times larger than the radio frequency spectrum, VLC is seen as a way to make up for the limited bandwidth of radio frequency.
The industry has produced very high data transmission rates, which makes it competitive. Even though the signal can't go through walls or other obstacles, a direct line of sight isn't needed as long as the light is reflected from other surfaces.
The LED lights must be on for the signal to be sent, but they can be turned down to a very low level. If VLC becomes a reality, it will be better than Wi-Fi at sending data because it won't cause electromagnetic interference.
How does visible light communication work? VLC works a lot like radio transmissions when it comes to sending information, except that it does this with light from LEDs instead of radio waves. Professor of Information and Computer Sciences
at the University of Massachusetts Amherst, Jichang, says that in a VLC array, one LED can turn on and off a million times per second. Since LED lights are used in all of our buildings, businesses, streets, and cars,
we already have the infrastructure in place to use this technology. Also, any device with a camera, like a laptop, tablet, or smartphone, can act as a receiver and make the technology work. These LEDs also leak energy
in the form of side-channel radio frequency or radio waves. This energy could be used to power VLC devices. How are scientists planning to harness RF leakage? Xiong and his colleagues set out to create an antenna that could pick up this energy.
They made their antenna out of copper wires that were wound into coils. The antennas were then put to the test to see how much energy they could gather. The researchers found that the antenna could pick up more energy when it was connected to another item,
regardless of the coil's thickness or the number of times the copper wire was twisted. Researchers put the antenna in contact with things like wood, steel, walls, tablets, phones, and even laptops to see how much energy could be harvested.
The team found that the amount of energy collected went up when electronic devices were used, but the most energy was collected when the coil was in contact with the human body. In short, the future of 6G technology is amazing and will change the way we think about energy.
The human body will be used as an energy source which means that we could see a world where people are far more connected than ever before. This technology is still in its early stages, but it is clear that it has the potential
to revolutionize the way we live and work. We would love to hear your thoughts on this new technology in the comments below. Thanks for watching. If you enjoyed the video, please like it and subscribe to the channel,
