紫外線從來都是可免則免，而購買薯仔則是多多益善。989Please respect copyright.ＰＥＮＡＮＡYmSoH4NCR8

在大多數的情況下，陽光是我們接觸紫外線的最主要源頭。989Please respect copyright.ＰＥＮＡＮＡLr9DeFQIXu

太陽放出的紫外線根據波段可分為兩種，UVA和UVB。989Please respect copyright.ＰＥＮＡＮＡkROPFyLQUF
概要來說，UVA(320–400nm)會曬黑皮膚及引起皺紋，而UVB(280–320 nm)則會曬傷及曬紅皮膚。989Please respect copyright.ＰＥＮＡＮＡI2LN9SIZ41

根據世衛所訂下的方式，UV指數的計法是將總紫外線的能量除以25。989Please respect copyright.ＰＥＮＡＮＡfkndsmA2l0
指數高於6表示有高度曬傷風險，而高於11更會對人體構成危險。989Please respect copyright.ＰＥＮＡＮＡVp8vk9DjmK

（圖2）現今智能手錶、智能眼鏡等設備已逐漸普遍，有不少更設有光觸媒二氧化鈦(TiO2)等物料可以將紫外光量化成電流，然後再根據的電流強弱判斷出紫外線指數。989Please respect copyright.ＰＥＮＡＮＡwPmFVAngTV

（圖3）近日，有科學家研發出隨著紫外光強弱而變色的麻料（Ref1)，基於毛線表面凹凸不平，因而增加紫外光在裡頭多重折射的機會，變相使在感測方面比普遍的平面光觸媒更為靈敏。989Please respect copyright.ＰＥＮＡＮＡ0hZrmNfoVh

他們在文中展示出，改變原材料的做法，可達至不同效果，例如WIFI圖案展示出紫外線的強弱。989Please respect copyright.ＰＥＮＡＮＡ3Gmos1YXKc

（圖4）他們更成功製作出隨紫外光強弱而變色的麻繩，據稱布料彈性十足穿著上非常舒適，而且製作方法可套用在任何製衣物料上。989Please respect copyright.ＰＥＮＡＮＡHjgK8kUZC2

在文中，他們發揮了自己的小宇宙，縫出提子圖案，提子葉加上孔雀石綠感測pH，而提子則由紫外光織成麻繩用作感測UV之用。989Please respect copyright.ＰＥＮＡＮＡgBFi9q7Cvo
