～Screen printing and sensor～
A parent-child conversation one night.
Mother: "Please eat the canned food in the refrigerator soon."
Child: "Why?"
Mother: "The expiration date is today."
Child: "It can't be helped, I'll eat it."
Child: "Why?"
Mother: "The expiration date is today."
Child: "It can't be helped, I'll eat it."
My son opened the can and started eating the fruit inside. Then the bell rang for midnight.
Mother: "Don't eat it!! The date has changed, so the expiration date has passed!!"
Child : "Eh! It's in my mouth!! What are you going to do with it?!"
Mother: "After the time signal rings, spit out only what you put in your mouth!! It's dangerous!!"
Child : "******"
Child : "Eh! It's in my mouth!! What are you going to do with it?!"
Mother: "After the time signal rings, spit out only what you put in your mouth!! It's dangerous!!"
Child : "******"
In the past, we used our five senses to check the degree of pain in food.
However, recently, various processed foods have appeared, and it is no longer possible to judge with the five senses of human beings.

This story is a conversation about misunderstanding the expiration date, but if we can easily check the spoilage of food, such misunderstandings will disappear. If a sensor that can easily measure putrefactive substances is put into practical use, the problem will be solved. Also, food waste will be eliminated, and I think it will help us maintain our health.
In order for us to be able to use such sensors easily, we have to make them affordable. Screen printing is for that!! In fact, in the medical field, blood glucose sensors are manufactured by the screen printing method and are widely used. This is possible because screen printing can print anything.
In the future, if many types of sensors are developed by screen printing, our lives will become even richer.
※expiry date:
It is the date indicating the period when it is sufficiently possible to maintain all the expected quality when stored according to the prescribed method. However, even if the deadline has passed, these qualities may still be maintained. (From the Ministry of Agriculture, Forestry and Fisheries website)
