上课开小差眼镜会“黑屏”如果戴上美国人发明的Narbis眼镜,那么上课时就不能“开小差”了。因为一旦注意力不集中,眼镜的镜片就会变暗,甚至“黑屏”。老师向台下一看,就知道谁不专心!这种新奇眼镜,利用了神经反馈技术、电致变色镜片技术。它还可以帮我们训练大脑,让它长时间保持注意力集中。知道多一点神奇的变色现象变色现象普遍存在于自然界中,人们感兴趣的是一种可逆的变色现象,包括:电致变色、光致变色、热致变色和压致变色。电致变色,是指材料在外加电场的作用下改变颜色和透明度。电致变 If you wear a Narbis eyeglass that was invented by the Americans, then you can’t “discriminate” when you are in class. Because once the attention is not concentrated, the lens of the glasses will be darkened, or even a “black screen.” When the teacher looks at the audience, he knows who is not paying attention! This novelty glasses uses neural feedback technology and electrochromic lens technology. It can also help us train the brain and keep it focused for a long time. Knowing a little more Magical discoloration Phenomenon discoloration is widespread in the natural world. People are interested in a reversible discoloration phenomenon, including electrochromism, photochromism, thermochromism and piezochromism. Electrochromism refers to the change of color and transparency of materials under the influence of an applied electric field. Electro-induced change
