排尿是排除身體毒素的其中一道重要機制。511Please respect copyright.PENANALOWW6Kn1no511Please respect copyright.PENANAlsBvyKkDXB

若然相關肌肉無法正常運作的話,尿液便沒能夠有效從身體排出體外,更有機會導致屙尿一滴滴或者尿袋常滿的不良狀態。511Please respect copyright.PENANAS54RHzPtXa

(圖2)近日有科學家研發一條具有彈性的白帶,內含三款感應器,分別量度壓力、電力和溫度(Ref1)。511Please respect copyright.PENANAr0XXxRbjWL511Please respect copyright.PENANAQuO0zcXm76
511Please respect copyright.PENANAj3aD0QaUSR
白帶經過測試,拉扯三千次後仍然運作正常。511Please respect copyright.PENANAsfuSEY963Q

(圖3)圖中為白帶再加上具有彈性黑網的示意圖。511Please respect copyright.PENANAR8F6Vtz4Lk511Please respect copyright.PENANAfHJ9nNBEe3

如果壓力、電力及溫度感應器到達某一數值的話,便會驅動白帶發光,並同時引發白帶收縮的功能。511Please respect copyright.PENANAtthYk8Svwk

(圖4)科學家嘗試把整套裝置放在老鼠的尿袋外圍作實驗之用。511Please respect copyright.PENANA85MzhxR0aV511Please respect copyright.PENANAse03F2tZYh

如圖中所見,當尿袋膨脹至一定程度並觸發三個感應器到達一定數值後,白帶藍光觸發並作出收縮,達模仿肌肉收縮形態之效,尿液亦因而排出。511Please respect copyright.PENANAumhftsW03Q

如何將整套概念套用到人類身上作解決排尿問題之用,將是他們下一步要思考的問題。511Please respect copyright.PENANANEW31f4LTm
