What is Radio Paper?

Magnetic paper is also called electrochemical paper. It shows its special function by adding some special chemicals into ordinary raw materials and making it undergo an electrochemical reaction after being pressed or heated.

Magnetic paper

Right!

Magnetic paper is also called electrochemical paper. It is by adding some special chemicals to ordinary raw materials and making them occur after being stressed or heated.

This is a special

Depending on the chemicals contained in the paper, the displayed electrochemical changes are not the same, or recording like a magnetic tape, or writing with a stylus can show text traces, or the color of the paper can change with the surrounding temperature, thus

Scientists have developed a "recorder" that can turn news broadcasts received by radio radio into text, put electrochemical paper into the "recorder", and automatically print out "newspapers". After reading, delete the text marks on the paper and reuse it.

There is a kind of electrochemical paper. Seven sheets are stacked together and rolled on a printer. As long as the steel word is lightly touched on the first sheet surface, no ink ribbon or carbon paper is used, and the remaining six sheets will be printed with the same text. Much more convenient.

Electrochemical paper treated with liquid crystal compounds can report ambient temperature changes. A piece of red electrochemical paper, which turns green after touching the surface of the paper, blows a breath towards the paper, and turns yellow again; even in the morning and at noon, the color of the paper will change automatically. This paper is used industrially to Check the temperature. When you see a New Year's card thermometer on the market, put it on your forehead for a while and it will "tell" you if your temperature is normal. This is also what this electrochemical paper does.
