一提到噪声,我们就觉得它十分讨厌,因为它让我们耳根不得清静,令我们心烦意躁。但是,科学家认为,噪声也是一种能源。最近,法国研究人员开发出一种充电T恤衫,它可以在噪声环境下发电,为用户的随身小电器充电。在充电T恤衫的腹部位置安装有一张白色纸片样的压电薄膜,其大小和A4打印纸差不多。它发电利用的是压电效应,和我们耳朵听声后转化为神经脉冲的原理有些像。噪声冲击压电薄膜后,会引起薄膜产生振 When it comes to noise, we find it very annoying because it keeps us from being quiet and upset us. However, scientists believe that noise is also an energy source. Recently, French researchers developed a charging T-shirt, which can generate electricity in noisy environments, charging the user’s small appliances. A white sheet of piezoelectric film was installed on the abdomen of the charged T-shirt and was about the same size as A4 paper. It uses the piezoelectric effect of electricity generation, and our ears after listening to the principle of nerve pulse into something like. Noise impact piezoelectric film, it will cause the film to produce vibration
