How wonderful would it be if new technology could help the physically challenged? A smart wearable device that enables people with speaking disabilities to communicate normally is giving hope to those without a voice.
如果新技術(shù)能幫助殘障人士該有多好?一款可穿戴智能設(shè)備讓有語言障礙的人能夠正常交流，給那些無法發(fā)聲的人帶來了希望。

Tao Luqi, a research fellow at Chongqing University, used a material called graphene to produce an artificial throat with a tiny sensor that allows people with speech impairments to speak normally, according to a paper published in Nature Communications in 2017.Tao has continued his work on the device for the last four years.
據(jù)一篇2017年發(fā)表在《自然-通訊》的論文稱，重慶大學(xué)研究員陶璐琪用一種叫做石墨烯的材料制作了一個(gè)具有微型感應(yīng)器的人工喉，能夠讓有語言障礙的人正常地說話。在過去四年里，陶璐琪都在開展這一設(shè)備的研究工作。

Although it’s a tiny mechanical sensor, it can work wonders. The device can detect weak vibrations and can produce sounds across a wide spectrum, from 100Hz to 40kHz, China Daily reported. Humans can detect sounds in a frequency range from about 20Hz to 20kHz.
雖然這只是一個(gè)很小的機(jī)械傳感器，但卻可以創(chuàng)造奇跡。據(jù)《中國日?qǐng)?bào)》報(bào)道，這個(gè)裝置可以探測(cè)微弱震動(dòng)，并產(chǎn)生100Hz-40kHz的寬頻譜聲音。而人類可以感知到大約20Hz-20kHz的頻率范圍內(nèi)的聲音。

“Although the speaking impaired people can’t speak, their throats can vibrate,” Tao told The Paper. “If I put a device made of graphene into the throat of a person, it can detect the vibrations and make sounds using electrical signals.”
“聾啞人士雖然不能說話，但是喉嚨可以震動(dòng)，” 陶璐琪在接受澎湃新聞采訪時(shí)表示。 “如果我把一個(gè)石墨烯制成的裝置放進(jìn)人的喉嚨里，它就能探測(cè)到震動(dòng)，并通過電信號(hào)發(fā)出聲音?！?/font>

Even whispers, screams and coughs at different frequencies can be recorded and encoded by the device, and it can arrange them into groups. When the device detects the sounds in a particular group, it will reproduce the words, phrases or sentences, according to Tao.
甚至是不同頻率的耳語，尖叫和咳嗽都可以被該設(shè)備記錄，編碼，并進(jìn)行分類。陶璐琪表示，當(dāng)設(shè)備探測(cè)到特定組別中的聲音時(shí)，它就會(huì)重現(xiàn)單詞、短語或句子。

“But the speaking impaired people need to classify their own language sounds in groups and memorize them, just like typing keys on a keyboard,” Tao said.
“但聾啞人士需要將他們自己的語言聲音自行分組并熟記，就像在鍵盤上輸入按鍵一樣，”陶璐琪稱。

Tao’s artificial throat has brought the possibilities of graphene to reality. It’s been 17 years since the discovery of graphene, and the world has been waiting for the “wonder material” to provide groundbreaking innovations. At only the width of an atom, graphene is the thinnest material known to humans – and also the strongest. The material is also an efficient conductor of heat and electricity, and is ultra-lightweight, China Daily reported.
陶璐琪的人工喉將石墨烯的種種可能性變?yōu)楝F(xiàn)實(shí)。石墨烯已經(jīng)被發(fā)現(xiàn)了17年之久，全世界都在等待這種“神奇材料”帶來提供突破性的創(chuàng)新。厚度僅為一個(gè)原子的石墨烯，是人類已知的最薄的，最堅(jiān)固的材料?！吨袊?qǐng)?bào)》報(bào)道稱，超輕的石墨烯也是有效的熱導(dǎo)體和電導(dǎo)體。

“Graphene really does have fantastic properties and its potential is huge,” said Khasha Ghaffarzadeh, a director at UK-based research consultancy IDTechEx.
英國研究咨詢公司IDTechEx的一名主管卡莎·加法爾扎德說:“石墨烯確實(shí)具有神奇的性能，其潛力是巨大的?！?/font>

China has emerged as a key country for graphene production. Around 3,000 Chinese companies are exploring uses for graphene, according to government statistics in 2018, while half of the world’s graphene-related patents have been filed in China, according to China Daily.
中國已成為石墨烯的主要生產(chǎn)國。據(jù)《中國日?qǐng)?bào)》報(bào)道，我國政府2018年的統(tǒng)計(jì)數(shù)據(jù)顯示，約有3000家中國企業(yè)在探索石墨烯的應(yīng)用，世界上一半的與石墨烯相關(guān)的專利都在中國。

“It’s a brand-new science, and China is trying to take the lead,” said Neill Ricketts, chief executive at Versarien, a UK-based advanced material company.
“這是一門全新的科學(xué)，中國正試圖發(fā)揮帶頭作用，”英國先進(jìn)材料公司沃薩潤的首席執(zhí)行官尼爾·里基茨表示。
