～Think about power saving～
This year is the year when we have to think a lot about saving electricity. Until now, we have used a large amount of energy to carry out production activities. For example, a large amount of energy is used to form electrical circuit patterns. The finer the pattern, the larger the equipment required. Even more energy is required to move the device.
From now on, it is necessary to think about manufacturing with energy in mind. Even if a wonderful new product can be developed, the price of the product will be high if it is manufactured using large-scale, expensive equipment and a large amount of energy.

For example, if we can develop biosensors by printing and easily detect poisonous substances in drinking water, I think it will be very useful for health management in developing countries. However, if the price of the sensor rises, it will not be possible to spread the biosensor that we have developed.
Also, even if you have a wonderful idea, if the equipment costs money, it will not be possible to commercialize it.
Although screen printing is a simple printing method, it is possible to print fine patterns. Therefore, I tried to think whether it is possible to form patterns using natural energy without using electricity.
First, this printer that does not use electricity, the Hand printing machine HP-320 is in use. The squeegee is driven manually. The HP-320 uses a vacuum pump to fix the workpiece, but here we fix it with natural glue so as not to use electricity. Sunlight is used to dry the ink. Print on a sunny day and leave in direct sunlight. If you use fast-drying ink, you can dry it without putting it in an electric oven. By the way, how much micropatterns can be printed with this printer?
As a result of the author's experiment, 50 μm wide lines can be easily printed. In this way, if the screen printing method is used, fine patterns can be produced without using electricity.

Other printing methods cannot print without electricity, but screen printing has a method that can print without electricity. I would recommend it to anyone who is developing new technology.
Why not apply screen printing to energy-saving product manufacturing?
