Researchers at CU Boulder have developed a wearable device that changes the human body into a biological battery. The device is stretchy(弹性的) enough that you can wear it like a ring, sport band or any other thing that touches your skin. It also taps into a person's natural heat-employing thermoelectric generators to change the body's internal temperature into electricity. "In the future, we want to be able to power your wearable electronics without having to include a battery," said Jianliang Xiao, an associate professor at CU Boulder.

The concept may sound like something out of The Matrix film series, in which a race of robots have enslaved humans to harvest their precious organic energy. Xiao and his colleagues aren't that ambitious: Their devices can generate about 1 volt (伏特) of energy for every square centimeter of skin space-less volt per area than what most existing batteries provide but still enough to power electronics like watches or fitness trackers.

Scientists have previously experimented with similar wearable devices, but Xiao's is stretchy, can heal itself when damaged and is fully recyclable-making it a cleaner alternative to traditional electronics. "Whenever you use a battery, you're depleting(消耗) that battery and will, eventually, need to replace it," Xiao said. "The nice thing about our device is that you can wear it, and it provides you with constant power."

Just pretend that you're out for a jog. As you exercise, your body heats up, and that heat will radiate out to the cool air around you. Xiao's device captures that flow of energy rather than let it go to waste. "The thermoelectric generators are in close contact with the human body, and they can use the heat that would normally be sent into the environment," Xiao said.

博尔德大学的研究人员开发了一种可穿戴设备，可以将人体变成生物电池。该设备具有弹性(弹性的) 足够了，你可以把它戴成戒指、运动带或任何其他能接触到你皮肤的东西。它还利用热电发电机将人体内部温度转化为电能，利用人体的自然热量。博尔德大学副教授肖建良说：“未来，我们希望能够在不需要电池的情况下为您的可穿戴电子设备供电。”。

这个概念听起来可能像是《黑客帝国》系列电影中的东西，在该系列电影中，一群机器人奴役人类，以获取他们宝贵的有机能量。肖和他的同事们并没有那么雄心勃勃：他们的设备可以产生大约1伏的电压(伏特) 每平方厘米皮肤空间的能量比大多数现有电池提供的能量低，但仍足以为手表或健身追踪器等电子产品供电。

科学家们之前也曾试验过类似的可穿戴设备，但肖的设备具有弹性，损坏时可以自我修复，并且完全可回收，是传统电子产品的更清洁替代品。“每当你使用电池时，你就会耗尽电量(消耗) 肖说：“我们的设备的好处是你可以戴上它，它可以为你提供恒定的功率。"

假装你出去慢跑。当你运动时，你的身体会变热，热量会散发到你周围的冷空气中。肖的设备捕捉到了能量的流动，而不是让它浪费掉。肖说：“热电发电机与人体密切接触，它们可以利用通常会被输送到环境中的热量。”。
