Friction generators can generate electricity against the dam
Compared with traditional electromagnetic generators, friction generators have a series of incomparable advantages due to the unique mechanism of material surface electrification. First of all, the friction generator is made of a thin film polymer material and a thin film electrode material, has extremely light weight and a very small volume, and its energy density has a huge advantage compared with an electromagnetic generator. Therefore, it is particularly suitable for providing electrical energy to small appliances such as portable and wearable electronic devices or wireless sensor arrays.
Self-driven sensor data transmission can be achieved by driving tiny sensing devices. For example, when detecting the vibration of the bridge, the thin film friction generator can be attached to the detecting instrument, and the mechanical energy of the bridge vibration can drive the friction generator to send an electric signal, and the electrical signal can be transmitted to the detecting instrument for use as a monitoring signal. To achieve self-test of the instrument.
Secondly, the friction generators are made of large-scale industrial materials, and the structure is simple, the production is simple, and the production cost is much lower than other types of generators, which provides extremely favorable conditions for its wide application. For ordinary people, the greatest convenience brought by friction generators is probably mobile communication.
A friction generator can convert it into electrical energy by collecting the mechanical energy of a person's motion. For example, one can attach a friction generator to a shoe, or to a leg. When the person walks, the action of the foot pressing on the sole or the shaking of the leg is converted into a current by the friction generator, and these currents are collected and stored by the battery, thereby realizing charging of the battery. The walking speed is fast, the charging speed is faster, the walking speed is slower, and the charging speed is slower, but this does not affect the final use effect. This charging process does not require extra work, and it is very convenient to use the normal rhythm to do daily actions.
Finally, the unique structure of the friction generator provides a viable or even unique solution for collecting the mutual sliding between the two objects, which is unmatched by conventional generators. Not only that, friction generators have the potential to collect and transform mechanical energy in nature on a large scale, and are expected to become a new way of green energy supply.
“Collecting the mechanical energy in nature is the biggest idea of friction generators.” Wang Zhonglin said that it is not very easy to collect the mechanical energy of seawater floating. With the change of wind direction and the fluctuation of tides, the flow of seawater is uncontrollable. Therefore, although people know that there is huge energy in the sea, there is still no suitable way to collect it. In this regard, Wang Zhonglin believes that the friction generator may be able to solve this problem. In a sea of 1 square kilometer and 5 meters deep, a spherical friction generator is placed every 10 cm. Calculated according to the output power of each spherical friction generator of 1 mW, seawater flows 24 hours a day, 24 hours a day, theoretically, it can sustain nearly 100 megawatts of electricity, and can light 100,000 watts of light. By analogy, if such a device is placed in the sea on a large scale, its power generation will be considerable. When the friction generator covers an area of 20,000 square kilometers, its power generation capacity can be comparable to that of the Three Gorges Dam. The mechanical energy of seawater floating is very stable, and it does not float too much during day or night or seasonal changes.
