从技术上讲，移动设备的无线充电已经有一段时间了。无线充电设备通常包括内置接收器，其从单独的充电垫收集能量传输。只要将手机放在垫子上，它就在接收能量流的范围内。然而，我们今天看到的只是新的远程技术即将提供的越来越多的自由和便利的前奏。在过去的几年中，许多初创公司已经开发并演示了无线充电系统，允许用户从几英尺远的地方为他们的设备充电。最早将这种技术商业化的努力之一来自初创公司Witricity，它使用一种称为共振感应耦合的工艺，使电源能够产生远程磁场。当此磁场与手机的接收器接触时，会产生电流，为手机充电。该技术类似于可充电电动牙刷中使用的技术。很快，一个名为Energous的竞争对手在2015年消费电子展上推出了他们的Wattup无线充电系统。与WiTricity的耦合系统不同，Energous使用壁挂式电源发射器，可以通过蓝牙定位设备，并以无线电波的形式发出能量，这些能量可以从墙壁反弹以到达接收器。然后将波转换成直流电。虽然WiTricity的系统可以为距离最远7英尺的设备充电，而Energous的发明具有更长的充电范围，大约15英尺，另一家名为Ossia的创业公司正在进一步向远程充电迈进。该公司正致力于更复杂的设置，包括一系列天线，以无线电波的形式将多个电力信号传输到距离30英尺远的接收器。 Cota无线充电技术支持多个设备的充电，并且可以更加自由，无需担心电池耗尽。自Apple推出iPhone以来，智能手机的第一次概念即将迎来第二次转型，因为公司准备推出革命性的新功能。借助无线充电等技术，智能手机体验可能更加便捷，而灵活的显示屏将开辟全新的互动方式。希望我们不必等待太久。
英国南安普顿大学传媒学Assignment代写:智能手机技术的未来
Technically speaking, wireless charging for mobile devices has been widely available for some time now. Wireless charging devices are generally comprised of a built-in receiver that collects energy transmission from a separate charging mat. As long as the phone is placed on the mat, it’s within range to receive the flow of energy. However, what we see today can be considered merely a prelude to the increasing range of freedom and convenience that newer long-range technologies will soon deliver. Over the last few years, a number of startups have developed and demonstrated wireless charging systems that allow users to charge their devices from several feet away. One of the earliest efforts to commercialize such a technology came from startup firm Witricity, which uses a process called resonant inductive coupling that enables the power source to generate a long-range magnetic field. When this magnetic field comes in contact with the phone’s receiver, it induces a current that charges the phone. The technology is similar to what’s used in rechargeable electric toothbrushes. Soon enough, a competitor named Energous introduced their Wattup wireless charging system at the 2015 Consumer Electronics Show. Unlike WiTricity’s coupling system, Energous uses a wall-mounted power transmitter that can locate devices via Bluetooth and sends out energy in the form of radio waves that can bounce off walls in order to reach the receiver. The waves are then converted into direct current. Although WiTricity’s system can charge devices up to 7 feet away and Energous’ invention has a longer charging range of about 15 feet, another startup named Ossia is taking long range charging a step further. The company is working on an even more sophisticated setup involving an array of antennae to transmit multiple power signals in the form of radio waves to a receiver as far as 30 feet away. The Cota wireless charging technology supports charging of several devices and allows for even more free rein without the worry of battery drain.
For the first time since Apple introduced the iPhone, the concept of what was possible with a smartphone is about to experience a second transformation as companies are poised to introduce revolutionary new features. With technologies like wireless charging, the smartphone experience can potentially be more convenient while flexible displays will open up whole new ways to interact. Hopefully, we won’t have to wait too long.
