Most people only know that friction can generate heat, but they don't know that friction can also generate electricity. In fact, the phenomenon of friction starting point can be seen everywhere in our daily life. The current sound that everyone hears when they take off their sweaters is the standard phenomenon of friction electrification. Although the phenomenon of triboelectrification has many hazards, many interesting products can be designed if this phenomenon can be used reasonably. The charging ring exposed by Samsung this time is one of them. After wearing this charging ring, you only need to keep moving your fingers to generate a steady stream of electricity for storage. Although the electricity generated is limited, it is enough to charge the mobile phone.
In addition to friction electrification, the charging ring also has a working principle, which is heat absorption. It is understood that this kind of charging ring can continuously absorb heat and convert it into electric energy, which means that even if the wearer does not lift his finger, the electric energy of the charging ring can be supplemented by heat transfer. I don't think this is an extremely convenient design. In addition, the heat absorption function of the charging ring can also be used to absorb solar energy. After all, when the sun shines, it will generate some heat, which will be converted into electric energy by the halo for storage.
Judging from the news exposed at present, this charging ring charges the mobile phone through wireless charging, which means that people only need to wear a small ring to solve people's charging problem. I have to say that this is an extremely convenient product, and it is expected to be welcomed by people after promotion.
