能量收集进入可穿戴电子

　　能量收集进入可穿戴电子

　　电子设备越来越多地被集成到服装中并连接在一起。利用环境中的能量来驱动设备、连接，甚至提供一些时尚元素。

　　一个令人兴奋的能源收集发展领域是可穿戴技术。越来越多的电子产品被整合到服装中，无论是功能性的还是时尚性的。例如，音乐播放器被集成到大衣和时装设计师使用电致发光和LED显示器，往往与音乐，创造积极的服装。

　　这其中大部分都需要动力，能够利用振动、热能或太阳能直接驱动显示器和无线链路，或者为轻薄的锂聚合物电池充电，为这项技术提供了关键的一步。没有人想把他们的衬衫插到电源里充电，从环境中提供能量可以大大延长充电周期。

　　这在一些能源收集技术，特别是太阳能电池技术方面还需要向前迈进一步。虽然这种电池的效率提高了，以便能从室内照明中产生有用的能量，但玻璃或晶体硅基器件可能很重。然而，新一代的无定形柔性细胞正越来越流行于集成到服装中以提供动力。

　　One such example comes from researchers at the Australian National University， who have developed a thin， flexible solar panel called Sliver Cell. The technology has been developed for military use as wearable solar panels to power equipment and creates a step to more rugged yet flexible cells.

　　Washing clothes with integrated electronics has also been seen as a major drawback. One breakthrough here comes from researchers at Seibersdorf Laboratories and the Austrian Institute of Technology （AIT）， who have managed to weave a standard NFC radio tag and antenna into garments in such a way it can be washed.

　　The antenna is integrated into the fabric as it is made， with the NFC chip added by hand. The process is managed in such a way to enable the garment to be washed at 60°C， spin dried and even ironed with a conventional electric iron， all without damaging the tag. This allows NFC-enabled washing machines to take data directly from the clothes for the particular washing program.

　　The drive to wearable electronics is also creating new approaches to the underlying technology. Space researchers at NASA have created a switching memory out of copper that can be weaved and so integrated directly into the fabric of clothing.
