We can express thoughts and feelings and send sounds and pictures on our smartphones today.
我们今天可以通过智能手机表达思想和情感，发送声音和图片。
We can’t send tastes, smells or touch. But some scientists in Britain are trying to develop a way for smartphones to do that.
我们还无法发送味道、气味或触觉。但英国的一些科学家正试图开发让智能手机实现这些功能的方法。
To give users a sense of taste, Adrian David Cheok and some other scientists designed two electrodes (电极片).
为了给用户带来味觉体验，Adrian David Cheok 和其他一些科学家设计了两个电极片。
“You put these two electrodes in your mouth, you put your tongue in between and then your tongue will get a virtual taste perception (虚拟味觉) in your brain,” said Professor Cheok.
“你把这两个电极放入口中，将舌头置于其间，然后你的大脑就会产生虚拟味觉感知。”Cheok 教授说。
They have already created sour, salty, sweet and bitter tastes.
他们已经成功模拟出酸、咸、甜和苦四种基本味道。
A device called “Scentee” permits users to have the sense of smell.
一种名为“Scentee”的设备能让用户获得嗅觉体验。
Scientists put a Scentee into a smartphone, and it can spray (喷射) small clouds of fragrance, including flowers, fruits and coffee.
科学家将 Scentee 装入智能手机，它可以喷洒微小的香气云团，包括花香、果香和咖啡香。
Professor Cheok says the person speaking can activate (激活) the device.
Cheok 教授表示，说话者可以激活该设备。
Scentee holds a container with about 100 different smells. The container must be replaced when all the smells run out.
Scentee 内含一个可容纳约 100 种不同气味的容器；当所有气味用尽后，需更换容器。
The sense of touch comes from a ring-like device. It is connected wirelessly to the smartphone.
触觉体验来自一个环形装置，它通过无线方式与智能手机连接。
“I can be in London and my friend can be in Tokyo, and I can squeeze my finger and then they’ll get a squeeze on their finger through the Internet.”
“我可以在伦敦，我的朋友可以在东京，我捏一下手指，他们就能通过互联网感受到手指被捏的感觉。”
“It’s a way of touch communication with small mobile devices,” Professor Cheok said.
“这是一种通过小型移动设备进行触觉交流的方式。”Cheok 教授说。
Professor Cheok hopes devices like these will someday be added to houses. He says they may change the future of long-distance communication.
Cheok 教授希望这类设备有朝一日能融入家庭生活。他说，它们可能会改变远程通信的未来。
