導(dǎo)讀：石墨烯，一種神奇的材料，能夠讓有語(yǔ)言障礙的人“說(shuō)話”，從此不再被交流困擾。如今，中國(guó)正大力發(fā)展石墨烯在各個(gè)領(lǐng)域內(nèi)的應(yīng)用……

How wonderful it would 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.

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. Tao has continued his work on the device for the last few years.

Although its a tiny mechanical sensor， it can work wonders. The device can detect weak vibrations and can produce sounds across a wide spectrum， from 100 Hz to 40 kHz， China Daily reported. Humans can detect sounds in a frequency range from 20 Hz to 20 kHz.

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(yǔ)言障礙的人能夠正常交流，給那些無(wú)法發(fā)聲的人帶來(lái)了希望。

雖然這只是一個(gè)很小的機(jī)械傳感器，但是可以創(chuàng)造奇跡。據(jù)《中國(guó)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(lèi)可以感知到 20Hz—20kHz 頻率范圍內(nèi)的聲音。

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.

Taos artificial throat has brought the possibilities of graphene to reality. Its been 18 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.

“Graphene really does have fantastic properties and its potential is huge，” said KhashaGhaffarzadeh，? a? director? at UK-based research consultancy IDTechEx.

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 worlds graphene- related patents have been filed in China， according to China Daily.

“Its 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.

甚至是不同頻率的耳語(yǔ)、尖叫和咳嗽都可以被該設(shè)備記錄、編碼，并進(jìn)行分類(lèi)。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(yǔ)或句子。

中國(guó)已成為石墨烯的主要生產(chǎn)國(guó)。據(jù)《中國(guó)日?qǐng)?bào)》報(bào)道，我國(guó)政府2018年的統(tǒng)計(jì)數(shù)據(jù)顯示，約有3000家中國(guó)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(zhuān)利都在中國(guó)。
