▌作品介绍：我的家离学校3公里，每天上晚自习回家天很黑，看不清路是我们学生面临的困难，头上戴灯帽，拿手电筒都不是很方便。 我的创意是“人体压电自行车”利用骑车的动力压电产生电能、照明，使回家的路不再黑暗，我们上晚自习再也不害怕黑暗了。
此文自动翻译Introduction:My home is 3 kilometers away from the school. It’s very dark to study by myself every night. It’s difficult for our students to see the road clearly. It’s not convenient for them to wear lamp caps and hold flashlights. My idea is that “human piezoelectric bicycle” uses the power of piezoelectric bicycle to generate electricity and lighting, so that the road home is no longer dark, and we are no longer afraid of darkness in the evening of self-study.
