Weaving Wearables into Everyday Life

　　Weaving Wearables into Everyday Life

　　对于那些跟随厂商社区，可穿戴技术的概念是没有什么新的。平台如Arduino Lilypad使制造商开发各种可穿戴式系统，从艺术电子织成的衬衣和裙子，通过T恤，告诉我们有多少未读邮件。这些项目大多有与他们相关的乐趣或自我表现的元素，但越来越多的工程师被要求开发可穿戴产品的电子产品。第一波消费设备一直以智能手表为主，连大行业的名字也一直在努力结合设计、显示和电池续航。继各种人群资助网站的更新，很明显，有很多创新，在该地区的可穿戴式传感器。

　　例如，在医疗卫生领域，一个项目在Kickstarter上发起了名为紫。紫色是一种可穿戴式传感器，测量我们接触到多少UVA和UVB辐射，让我们享受阳光来获得我们的维生素D，但“霜”之前曝光对我们的健康有害。另一个项目，狮子座，是一个感知系统戴在小腿肌肉在锻炼和提升在Indiegogo。使用3D运动，心率和肌肉活动传感器，该设备允许用户改善他们的锻炼制度，避免潜在的伤害。

　　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.
