Japanese scientists have developed the world's smallest magnetic sensor

according to Kyodo news agency, the international research team led by Fenghe Yamada, a distinguished associate professor at Chiba University in Japan, published an article on the 20th in the online edition of the British science magazine natural nano gb/t 15788 (2) 005 "test methods for wide strip stretching of Geotextiles and related products" science and technology ", saying that by using organic molecules, The world's smallest magnetic sensor has been successfully developed. The sensor can be used to read the information recorded in computers and other devices

Yamada said that the sensor uses phthalocyanine organic molecules that produce isochromic inks and pigments. The molecular diameter is only one millionth of a millimeter. Compared with the previous inorganic material sensors such as metal or rare earth, the new method can reduce the size of the sensor to 1% when cleaning the dirt or dust on the surface of the instrument. The sensitivity of the new sensor is increased to about 10 times of the previous one, and it is cheap and durable

Yamada said: the industry may also start to see structural adjustment. "This research will be conducive to the miniaturization of computers. For Japan, which does not have rare earth and other resources, this is an important discovery, and is conducive to the development of environmentally friendly products."
