2015年，在抵达 回到未来》第二部, Marty Mcfly changes into the outfit of the future. His Nike sneakers lace themselves up, automatically adjusting to fit his feet perfectly. His jacket shrinks to fit his arms and even has a self-drying function that is activated after he jumps into the pond during his hoverboard chase with Biff. Later in the movie we even see future-Marty’s kids wearing what we would now refer to as AR or VR goggles. This was the 2015 envisioned in the sci-fi classic. Now in 2020, how close are we to this reality?
The term “wearable tech” covers a wide range of devices that are worn by a user on their body to perform certain functions. They can be divided into three main categories: smart accessories, smart clothing, and healthcare devices. The main functions of these devices are usually for monitoring health-related statistics and acting as an extension of your smartphone, while devices like VR and AR goggles are also used for entertainment.
Today’s wearable technology is not yet as advanced, affordable, and commonplace as Back to the Future imagined they would be by now. However, some ideas have indeed become reality. 耐克和其他各种鞋品牌都推出了智能运动鞋. VR和AR护目镜正逐渐成为许多行业的关键工具，包括游戏、娱乐，甚至医疗保健和制造业。
One type of wearable tech that still falls behind the film’s vision is smart clothing. Sadly, Marty Mcfly’s self-tailoring, self-drying jacket is not yet available. Nonetheless, there is promising development in the world of technological clothing.
什么是智能服装？
智能服装是指集成了技术的服装，可以以某种方式为穿着者服务。例如，有 聪明的袜子 that collect data of how the user’s foot falls while walking or running. There are also 瑜伽裤 that use haptic feedback to detect the accuracy of the wearer’s pose and send small vibrations to prompt the wearer to make adjustments.
In these examples, sensors are woven into the clothing item to collect data. Other types of smart clothing have integrated devices that can screen calls or track one’s location.
下一个将智能服装带入主流的电池突破是什么？
One current limitation for smart clothing is the size and design of batteries. Even though sensors and control panels can be small, batteries still have bulk and shape to them. Often times a battery pack would have to be attached to the clothing item — an awkward and hard unit that does not seamlessly blend into the clothing article.
很快就会有一个解决方案。电池研究人员已经开发并正在测试柔性和可拉伸的电池组。这一突破对智能服装来说将是巨大的，允许电池更不明显地集成到织物中。这将给用户带来更顺畅、更愉快的体验。
这一概念仍有局限性，特别是在以下方面 拉伸如何影响电池的导电性和容量. 尽管如此，它还是很有希望的，有可能使我们更接近《回到未来》中描绘的服装。
可穿戴技术和智能服装的电池还会有什么问题？首先，安全将是一个主要考虑因素。由于这些设备是穿在人体上的，任何过热或泄漏都会直接接触到皮肤，构成重大安全隐患。像固态电池这样的电池，用固体电解质取代易燃的液体电解质，可以减轻这种担忧。
在缩小电池尺寸和增加容量方面的进展也将大大有利于可穿戴技术。虽然智能服装的能量和电力需求并不高，但小电池将帮助服装项目感觉不像是一个设备，而更像是未来主义的服装。
结论。
在融入主流之前，智能服装仍有一些路要走。这些物品的奢侈价位仍然阻碍着它被更广泛地采用。然而，电池并不是这项技术需要完善的唯一部分；鉴于自动系带的鞋子确实存在，没有理由不相信自动调整的外套也可能很快出现。
