Let's take a look, this is the latest experimental result from the University of Washington in the United States - a mobile phone that does not need to be charged.

Although this prototype phone looks like a circuit board, it can actually make calls, integrates a complete GSM chip, and has a 3.5mm headphone jack. Its unique feature is that it has a built-in solar cell the size of a grain of rice, only 3.5 milliwatts, which can absorb ambient light and wireless signals at any time, and convert them into the power required by the mobile phone.

The developer successfully made Skype calls using the phone, and the calls worked fine. In the future, it is expected to add functions such as electronic ink screen and video streaming, so that this circuit board looks more like a real mobile phone.

"You can imagine that in the future, as long as there is Wi-Fi, you can provide power to your mobile phone," said developer Vamsi Tall. Although the technology is still in the early stage of research and development, I believe that many friends, like me, want to live In a world where you no longer need to search for power outlets all over the world and carry a power bank with you.
