The flexible lead-free piezoelectric sodium bismuth titanate potassium nano power generation device is convenient to carry and capable of supplying power automatically.

Description

technical field [0001] The invention relates to a nanometer power generation device, in particular to a flexible lead-free piezoelectric bismuth sodium potassium titanate nanometer power generation device and a manufacturing method thereof. Background technique [0002] With the development of society, the demand for energy is increasing. Traditional power generation methods such as hydropower, nuclear fuel power, thermal power, and chemical power will not only consume a lot of natural resources, but also cause a lot of environmental pollution. At the same time, there are a lot of losses and dangers in the process of electric energy transportation, which increases the cost. [0003] The British "Science" reported that the research group of Professor Wang Zhonglin from the Georgia Institute of Technology in the United States successfully converted mechanical energy into electrical energy at the nanoscale, and successfully studied a nano-power generation device for the first t...
