| Scientists create biodegradable paper connected to the Internet |
Japanese researchers have developed a new type of biodegradable paper that can be connected to the Internet: nanotechnology. This new sheet is only 1 mm thick and can be used to collect soil moisture data without creating toxic electronic waste.
The research team believes that this type of paper can change the way data is collected in the wild and hopes to offer an environmentally friendly alternative to non-degradable plastics, as is common in electronic devices.
The project was developed by the University of Osaka Institute of Science and Industry (ISIR) from a team of scientists led by researchers in applied chemistry (Takaki Kasuga).
According to a report published by the Asahi Shimbun newspaper, the nanotubes are made of ultra-fine fibers believed to be 1,000 times thinner than ordinary paper fibers and have a smooth plastic-like surface.
Nanotubes have been invented to be degradable, have minimal environmental impact and do not require expensive maintenance. After being put on the ground for 40 days, 95% of the analysis was performed and its metal parts covered with non-toxic rust.
The researchers added a small moisture to the nanotechnology, which allows the paper to read moisture and water vapor in the air or soil in which they are found.
Using a hygrometer, the paper can read the humidity for scientific research or help farmers track the fields that need irrigation.
The hygrometer sends data to a small wireless sensor that allows data to be transmitted to other devices over the Internet without immediate monitoring.
Nanotubes are part of Internet of Things (IoT), an online network with which various elements can communicate independently.
The small size ensures that nanometers can be freely poured wherever data is recorded. Since it is biodegradable, it does not have to be recycled again.
After the team's first tests, he plans to develop a new version that will allow him to make other types of measurements. One idea is to discover an integrated gas that can read volcanoes or other dangerous or difficult areas.
According to the United Nations Environment Program, this innovation was made at a time when the amount of e-waste worldwide is increasing and up to 50 million tons of e-waste are generated every year.
Kasuga told the newspaper: "Biodegradable electronics are generally expected to thrive in the coming years." The next step in a research project on biodegradable nanotechnology is to research new technologies to control the time it takes to dismantle the equipment. "
