Composite power generation unit

The present invention is a power generation device, and particularly relates to a hybrid power generation device that generates a combined power generation effect using a coil and a piezoelectric element.

Looking back on the past, since the industrial development in various fields since the industrial revolution, human beings have relied heavily on fossil fuels to provide energy. In addition to the gradual depletion of global fossil energy resources, the greenhouse gases have been caused by the emissions of fossil fuel combustion. And trigger the issue of climate change. In addition, petrochemical fuels are also limited and cannot be mined indefinitely. If they are gradually exploited, in addition to reducing the amount of these natural resources, they will have an unpredictable impact on the ecology and environment of the earth. In order to solve the problem of fossil fuels, the sustainable development of renewable energy has become an inevitable trend in the development of energy policies in various industrial countries. The application of green energy is in addition to solar energy, wind energy and heat energy; the other is to convert the kinetic energy of exercise into electric energy. Among them, running or brisk walking is the most popular form of exercise. If these energy can be properly applied, it should be produced. A lot of electricity.

At present, most of the sports power generation is about using generators with larger power generation. Most of them are used together with vehicles. Due to the large resistance and energy consumption, the use situation is not common. At present, most of the general public's sports can choose more unrestricted running and fast-moving sports. At the same time, people often wear mobile phones to listen to music or do health management. However, if the mobile phone has no power, it will not be able to achieve the function we want. Therefore, if you can charge your mobile phone or battery at the same time, it will be very energy-saving and environmentally friendly.
