There are wireless ways to keep phones charged.


Our world is filled with wireless technology that is capable of transferring complex digital information to and from smartphones, GPS devices, and all other manner of gadgets. Now, there is a new wireless approach to charging these devices that is quickly becoming a _(1)_ for the modern consumer. Who could have ever thought being able to transfer power from one device to another was possible?


Wireless charging means that you will no longer have to _(2)_ getting tangled up in a mass of cords when you want to charge up your phone, PlayStation Portable (PSP), or electric toothbrush. This technology was actually first _(3)_ in the 19th century by the famous electrical engineer Nikola Tesla. Recent advances in miniaturizing technology, improving its efficiency, and honing its applications have finally made Tesla's dream _(4)_ in our wireless 21st century.


Wireless chargers work by transferring energy over a short distance using an electromagnetic field. To charge a device, you need both a transmitter and a receiver. The transmitter is plugged _(5)_ a power source and creates an electromagnetic field which induces a charge in the receiver placed in the vicinity.


Companies like Powermat Technologies and WiTricity have already developed such devices to be used with mobile phones and to power kitchen _(6)_. There are even bigger plans to develop devices which can _(7)_ power to an entire roomful of machines like TVs, lights, and laptops from a single source. In the future, even electric cars could be completely charged by wireless units embedded in the roads.

神奇的无线充电器

现在可以用无线的方式为手机充电。


我们的世界到处都充满了无线科技,它可以将复杂的数字讯息转移至智能型手机、全球定位系统装置及其他各式各样的装置,或是由这些装置将讯息转移至他处。如今,对于现代消费者而言,有一种新的方式很快就要成真了,那就是使用无线的方式为这些装置充电。有谁曾经想过把电力从某个装置传送到另一个装置是有可能的?


无线充电意味着当你想要为你的手机、PSP或是电动牙刷充电时,再也不必担心被一大堆电线缠住了。这项科技实际上最早是在 19 世纪由知名的电机工程师尼古拉.特斯拉所发想出来。而近年来随着科技的微型化、效率提高以及改善应用功能等方面的进展,最终让特斯拉的梦想在无线化的 21 世纪变得可行。


无线充电器的运作是利用电磁场将能源转移一小段距离。要替某样装置充电的话,你必须同时有传送器和接收器。将传送器插入电源,并制造出电磁场以使放在附近的接收器感应到电荷,进而充电。


Powermat和 WiTricity 等公司已发展出这类可使用在手机,并可启动厨房电器的装置。他们甚至还有更远大的计划,要发展出一种装置,可以透过单一电源,将电力传送到整间房子里的电器,像是电视、电灯和笔记本电脑等。在未来,即使是电动车也可以透过装在路上的无线装置完全地充电。


答案:  1.  D   2.  A   3.  C   4.  B   5.  A

   6.  C   7.  B



尼古拉.特斯拉(1856年 7 月 10 日-1943 年 1 月 7 日)是世界知名的发明家、物理学家、机械工程师和电机工程师。拥有塞尔维亚血统的他出生在克罗埃西亚。特斯拉被认为是历史上一位重要的发明家。他在 19 世纪末和 20 世纪初对电和磁的贡献也是知名的。特斯拉的专利和理论催生了现代的交流电电力系统,其中包括交流电动机,藉此帮助推动了第二次工业革命。


在美国,特斯拉在历史上或通俗文化上的名声可以媲美任何其他的发明家或科学家。1893年他展示了无线通信之后,就成为了美国最伟大的电机工程师之一而备受尊敬。许多他早期的成果都变成了现代电机工程的先驱。在 1943 年,美国最高法院承认他为无线电的发明者。(数据源:维基百科)
