摘　　要：在当今世界,电力、能源和安全是人们日常生活的基本要求。为了应对日益增长的能源需求,最终的解决办法是实施可再生能源,然后将其用于人类的安全。可再生能源需要以它们各自正确的方式实施。研究基于压电传感器片的迈步发电装置,并演示了如何利用这些能量实现建筑物疏散照明。我们在传感器的下方和顶部分别固定了木板和可移动网螺栓,利用压电传感器系统,行人可以通过迈步向发电装置施加电能,另外,将硅凝胶粘贴在位于下部木板空洞中的所有传感器顶部。当有人踩到板上时,就会自动施加压力。在木板的顶部和底部设置了一个孔,以便随时调整在底部和顶板之间安装的可移动网螺栓。烟雾传感器用于启动灯光。使用这种设备,我们实现了建筑物疏散路径上的LED灯正常运行。结果表明,这种安全发电的设计和方法具有一定的实用价值,同时也满足了全球对能源的需求。Safety,power,and energy are the basic requirements in the modern era.The ultimate solution is to implement renewable energy sources to deal with the growing desire for power and then utilize it for human safety.It is required to use these sorts of renewable energy in the right way.In this paper,we studied footsteps for power generation from piezoelectric sensor sheets.For illustration,how to use that energy for the evacuation lighting of the buildings,we fixed the moveable net bolts below and top of the sensors with wood sheets to generate electrical power from footsteps using a piezoelectric sensors system.Also,we put silicone gel on top of all sensors located on the lower wood plate,and then impulsive pressure is applied when somebody takes a step on wooden sheets.A hole is fixed at the bottom and on the top of wood sheets to adjust moveable net bolts among the plates.A smoke sensor was used to initiate the lights.Using this equipment,in the evacuation path of the buildings,we can run LEDs or lights.It has revealed that these types of approaches and designs of electrical power generation have specific values for safety purposes,and generally to encounter the amount and requirements of energy.
