Japan has successfully manufactured a biodegradable humidity sensor

The biodegradable humidity sensor helps farmers determine which areas of the farm need to be watered by transmitting a signal that varies according to the soil moisture.

Japanese scientists have successfully built a biodegradable humidity sensor for use in agriculture.

Most sensors will decompose in about 40 days.(Artwork: Bigfriendlyread).

The team, led by Kasuga Takaaki of Osaka University, has created a sensor circuit board made primarily of microscopic cellulose fibers.

This device will allow farmers to identify which areas of their farms need to be watered by transmitting a signal that varies according to the soil moisture .

According to the researchers, most sensors will decompose in about 40 days. However, this version still contains a small amount of non-biodegradable metal and requires external power to operate.

The team hopes to overcome the above disadvantages when commercializing this product.

NHK broadcaster quoted Kasuga researcher said that in the future, these sensors will help promote the technology of connected things (IoT) in the field of agriculture. As a result, agricultural activities will be managed more effectively.
