Samsung applied for the patent of "charging ring". Do you think this charging ring is practical?

Recently, a patent document published by Korea Industrial Property Information Service Center shows that Samsung applied for a patent for a portable wireless charger that can generate energy. The patent shows a ring that relies on the human body to generate electricity, and it can also charge the mobile phone wirelessly. According to the patent description, this charging ring can generate electricity and store it through the heat generated by finger movement and skin temperature. The specific use method is the same as the wireless charging treasure in our current life. If the user needs to charge, he only needs to put the mobile phone device near the charging ring for wireless charging, which is very simple and convenient.

The working principle of the charging ring in addition to the above basic working principle and usage, specifically, the charging ring? There is also a small battery to store the generated electricity. As long as the small battery has electricity, you can put the mobile phone with a ring in the wireless charging place of the device to charge it.

In other words, this charging ring is not directly powered by the battery. If it is explained by the principle of power generation, it can also be understood as a small ring generator, which sounds very high-tech, and it is not a level of technology with our usual charging treasure. However, in order to charge the equipment, there will be a small battery in the charging ring to store the generated electricity.

When the ring wearer wants to charge, the mobile phone device can be placed near the charging ring for wireless charging.

Whether it can become a reality is a proposed patent, which may be realized under certain experimental conditions, but there is still a big gap between experiment and real life. In order to be used in daily life, the ring needs to deal with many practical problems, so it is still uncertain whether the device will become a reality or only exist in the laboratory.

In fact, similar wearable devices are very common in life, such as smart bracelets and smart watches. This wearable device is not only a hardware device like a mobile phone, but also an extension of human senses, which can help human beings process and transmit information.
