Solid Chinese watch inside the water

While the world's watch industry focuses on studying ways to enhance watches resistance to water, the Chinese University of Tianjin went in the other direction and developed the first smart watch in the water..

Professor Huang Xian from the Department of Biomedical Engineering, at the Faculty of Microscopic Machinery and E -Engineering at the University of Tianjin, succeeded in developing the nanoparticles used in the manufacture of electronic products, which can achieve a pollution -free recycling and fast electronic products, and represents an innovative and harmless methodIn disposal of electronic waste.

Electronic products made of this material can be used naturally for a long time under normal use conditions.And when you want to get rid of it and recycle it, you just need to throw it into the water to decompose within a few days (40 hours).While it remains possible to recycle chips and other components, which are not polluted and can increase the rate of use of electronic components, and achieve the rapid recycling of electronic products without pollution.

Electronic waste contains a lot of precious metals, such as gold, silver, platinum, cobalt and Andium, but due to the difficulty and high cost of recycling, it has always been at a low level, where 53 have been produced..6 million tons of electronic waste in 2019, but the recycling rate was at only 2 %.The new materials developed by the Huang Shean team provides a new idea to solve the problem of electronic waste, according to the Chinese newspaper "Al -Shaab".

In addition, Huang Shean says that these substances can be used in the field of medicine and treatment, and can decompose on their own within the human body and without melting due to race.Hence, some of the medical devices that are planted for the purpose of surgery or treatment in the human body can melt inside the body after the success of its treatment..
