Weaving Wearables into Everyday Life

　　對(duì)于那些跟隨廠商社區(qū)，可穿戴技術(shù)的概念是沒(méi)有什么新的。平臺(tái)如Arduino Lilypad使制造商開(kāi)發(fā)各種可穿戴式系統(tǒng)，從藝術(shù)電子織成的襯衣和裙子，通過(guò)T恤，告訴我們有多少未讀郵件。這些項(xiàng)目大多有與他們相關(guān)的樂(lè)趣或自我表現(xiàn)的元素，但越來(lái)越多的工程師被要求開(kāi)發(fā)可穿戴產(chǎn)品的電子產(chǎn)品。第一波消費(fèi)設(shè)備一直以智能手表為主，連大行業(yè)的名字也一直在努力結(jié)合設(shè)計(jì)、顯示和電池續(xù)航。繼各種人群資助網(wǎng)站的更新，很明顯，有很多創(chuàng)新，在該地區(qū)的可穿戴式傳感器。

　　例如，在醫(yī)療衛(wèi)生領(lǐng)域，一個(gè)項(xiàng)目在Kickstarter上發(fā)起了名為紫。紫色是一種可穿戴式傳感器，測(cè)量我們接觸到多少UVA和UVB輻射，讓我們享受陽(yáng)光來(lái)獲得我們的維生素D，但“霜”之前曝光對(duì)我們的健康有害。另一個(gè)項(xiàng)目，獅子座，是一個(gè)感知系統(tǒng)戴在小腿肌肉在鍛煉和提升在Indiegogo。使用3D運(yùn)動(dòng)，心率和肌肉活動(dòng)傳感器，該設(shè)備允許用戶(hù)改善他們的鍛煉制度，避免潛在的傷害。

　　Behind both of these products are similar core technologies that enable energy-efficient data collection and sharing of information via a wireless link. By using the user‘s smartphone and an appropriate app to display results， a power-sapping display is avoided. A careful look at the photos on the Violet Kickstarter campaign page shows that it is Bluetooth Low Energy （BLE） that is enabling these new products.

　　Originally introduced as Wibree by Nokia， the Bluetooth SIG merged this low-power wireless technology into the Bluetooth Core Specification version 4.0 in 2010. BLE， marketed to consumers as Bluetooth Smart， is unfortunately not backwards compatible with pre version 4.0 Bluetooth devices. However， since many Bluetooth chipsets have a programmable element， some users may simply need a firmware upgrade to gain support. This is possible because BLE uses the same radio and baseband technology as Bluetooth Basic Rate （BR） and Enhanced Date Rate （EDR）， albeit with a different modulation scheme. Having established Bluetooth as a standard feature of phones in the minds of consumers， the addition of BLE to the specification makes it easier to launch power-sipping accessories and build on the success of the smartphone market， rather than have to develop workarounds to achieve a suitable battery-life for such products.
