　　Do you like working up a sweat? Or do you feel likemaybe sweat should work for you? Well, hold on toyour sudoriferous glands. Because researchers havedesigned a device that could someday producepower from your perspiration. The schvitzy schemewas presented at the annual meeting of theAmerican Chemical Society in San Francisco.

　　你喜欢出汗吗?你觉得汗水能为你做什么?嗯，你可要控制好你的汗腺了，因为研究人员已设计出一款将来能够利用你的汗水发电的设备。该schvity设计方案已于旧金山的年度美国化学学会中提出。

　　Strenuous exercise generates lactate—the molecule that makes overworked muscles burn.Athletes sometimes evaluate their fitness by checking the lactate levels in their blood. Toreduce blood draws, researchers came up with a monitor that could measure the lactate insweat. The device they designed strips electrons from lactate, which creates a small electriccurrent. The strength of the current reveals the amount of lactate.

　　剧烈运动产生的乳酸能使过度劳累的肌肉燃烧。有时，运动员通过测量自己血液中的乳酸浓度来评估自身的健康状况。为减少抽血次数，研究人员发明出一个能够测量出汗液中乳酸浓度的监测器。该设备能使乳酸中的电子脱离，从而产生一小段电流。电流的强弱代表乳酸含量的多少。

　　To test the system, 10 volunteers wore the arm-patch sensor while they rode a stationarybike. And the device recorded the current they delivered as they dripped.

　　为检测该系统，10名志愿者一边骑着健身脚踏车，一边戴着臂补丁传感器。当他们流汗时，该设备便会记下电流强弱。

　　Then the researchers thought, what if they could tap into this energy to develop a sort ofsweat-powered “bio battery?” Their proof-of-concept setup topped out at only about 4microWatts of juice—not even enough to run a watch. But with better electronics, exercising inthe future could make dirty clothes and some clean energy.

　　后来研究人员又突发奇想：是否能利用这种能量来发明一种依靠汗水发电的“生物电池”?他们的概念验证装置只产生4微瓦电——这还不足以使一只手表正常运转。但随着电学的日趋完善，运动产生的汗液说不定在将来的某一天可以为清洗衣物，和创造清洁能源发挥作用。

　　词语解释

　　1.work up通过锻炼或高强度工作而产生

　　Even if you are not prepared to work up a sweat three times a week, any activity is better than none.

　　即使你不准备1周流3次汗，任何活动总比没有要好。

　　2.electric current 电流

　　Piezoelectric crystals produce an electric current when bent and have many uses — the igniter on a gas barbecue grill being one of them.

　　压电晶体在发生弯曲时能够产生电流，并且已有很多用途——燃气烧烤的点火器就是其中之一。

　　3. proof-of-concept 概念验证

　　This proof-of-concept implementation demonstrates that you can implement these specifications on resource-constrained devices.

　　该概念验证的实现说明了您可以在资源受限的设备上实现这些规范。

　　4. out of juice 没电了

　　I don't want to run out of juice and be stranded by the side of the road.

　　我可不想等车没电了被困在马路边。
