By using plant fiber as the main material, the Osaka University group succeeded in developing a sensor that is almost decomposed naturally and becomes soil, and it is attracting attention as a technology that can be used in the agricultural production field in the future. It is.

A research group of Takaaki Kasuga, a research fellow at Osaka University, has developed a sensor that makes electronic circuits using the material called cellulose nanofiber, which is a plant fiber, and decomposes most of it into soil.

The developed sensor is a mechanism that changes the frequency of the radio wave transmitted by humidity, and if it is installed in large fields, it can grasp the location where moisture is insufficient, but if it is buried in the soil, most will be decomposed after 40 days. It means that.

Currently, it is necessary to supply electricity as a power source, and it is said that a few metals such as silver used in the circuit part will not be decomposed. I want to improve it to a sensor that doesn't.

“These sensors help spread IoT technology that connects everything to the Internet in agriculture,” says Kasuga.
