The invention provides a recognizing system based on a friction nanometer generator. Electricity generating thin layer blocks made of different materials are arranged on a key part and a reading part of the recognizing system respectively, the two electricity generating thin layer blocks relatively move to form the friction generator, then the voltage is output, a recognizing array is formed by multiple electricity generating thin layer blocks in an array, and whether the key part and the reading part are matched or not can be determined by testing the output voltage. According to the recognizing system, the requirement for the work environment is low, and the recognizing system is convenient to manufacture and capable of being widely applied to entrance guard cards, bus cards, bank cards and other fields and has the advantages with which traditional magnetic cards are incomparable.
Description
technical field [0001] The invention relates to the technical field of identification systems, in particular to an identification system based on a friction nanogenerator. Background technique [0002] Identification systems are a common necessity in life. The earliest and most common identification system is the mechanical identification system, which is represented by locks. However, mechanical recognition suffers from the drawback of being easily replicated. [0003] With the development of science and technology, identification systems such as light, electricity, and magnetism have emerged. The most typical representative is the magnetic card. However, for the magnetic card, it is easy to demagnetize, and the reading part of the identification system requires additional power supply. This deficiency limits the applications of such identification systems. [0004] In 2013, Professor Wang Zhonglin from the Georgia Institute of Technology solved this problem with his wo...
