[雙語] 世界最小的計算機 面積只有1平方毫米

 

Scientists from University of Michigan have created the world's smallest computer system to help treat glaucoma patients. At just one square millimeter in size, the tiny device is a pressure monitor that is implanted in a person's eye.

美國密歇根大學的科學家近日發(fā)明了世界上最小的計算機系統(tǒng)用來治療青光眼患者。該系統(tǒng)面積只有1平方毫米，用于監(jiān)測壓力，可以植入青光眼患者的眼部。

It may be small but it packs a hefty punch, containing an ultra low-power microprocessor, a pressure sensor, memory, a thin film battery, a solar cell and a wireless radio with an antenna that can transmit data to an external reader device.

系統(tǒng)雖然微小卻五臟俱全，包括耗電極微的微處理器、感壓器、記憶體、薄膜電池，太陽能電池和帶有天線、可以將數(shù)據(jù)傳至外部接收器的無線電臺。

The system wakes every 15 minutes to take measurements and consumes an average of 5.3 nanowatts. It can store up to a week's worth of information. It requires exposure to ten hours of indoor light each day or 1.5 hours of sunlight.

這個監(jiān)測器每15分鐘“醒”一次，測量數(shù)據(jù)，平均耗電5.3豪微瓦。它可以儲存一周的數(shù)據(jù)信息。它每天只需10小時的室內(nèi)光線或者1.5小時的太陽光來充電。

The unit is expected to be commercially available in several years, and is already being touted as the future of the computing industry. A network of such units could one day track pollution, monitor structural integrity, perform surveillance, or make virtually any object, according to the scientists.

這個微型系統(tǒng)有望在數(shù)年內(nèi)完成商業(yè)化，并且被認為是計算機工業(yè)的未來發(fā)展方向?？茖W家稱這種微型系統(tǒng)聯(lián)網(wǎng)后可以用來監(jiān)測污染、建筑結構、巡邏以及追蹤幾乎任何物體。
