Do you like working up a sweat? Or do you feel like maybe sweat should work for you? Well, hold on to your sudoriferous glands. Because researchers have designed a device that could someday produce power from your perspiration. The schvitzy scheme was presented at the annual meeting of the American Chemical Society in San Francisco.
你喜歡出汗嗎？你覺得汗水能為你做什么？嗯，你可要控制好你的汗腺了，因為研究人員已設計出一款將來能夠利用你的汗水發電的設備。該schvity設計方案已于舊金山的年度美國化學學會中提出。
Strenuous exercise generates lactate—the molecule that makes overworked muscles burn. Athletes sometimes evaluate their fitness by checking the lactate levels in their blood. To reduce blood draws, researchers came up with a monitor that could measure the lactate in sweat. The device they designed strips electrons from lactate, which creates a small electric current. The strength of the current reveals the amount of lactate.
劇烈運動產生的乳酸能使過度勞累的肌肉燃燒。有時，運動員通過測量自己血液中的乳酸濃度來評估自身的健康狀況。為減少抽血次數，研究人員發明出一個能夠測量出汗液中乳酸濃度的監測器。該設備能使乳酸中的電子脫離，從而產生一小段電流。電流的強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 stationary bike. And the device recorded the current they delivered as they dripped.
Then the researchers thought, what if they could tap into this energy to develop a sort of sweat-powered “bio battery?” Their proof-of-concept setup topped out at only about 4 microWatts of juice—not even enough to run a watch. But with better electronics, exercising in the future could make dirty clothes and some clean energy.
后來研究人員又突發奇想：是否能利用這種能量來發明一種依靠汗水發電的“生物電池”？他們的概念驗證裝置只產生4微瓦電——這還不足以使一只手表正常運轉。但隨著電學的日趨完善，運動產生的汗液說不定在將來的某一天可以為清洗衣物，和創造清潔能源發揮作用。
