Embodiment Construction

[0038] The technical solutions of the present invention will be further described below with reference to specific embodiments, and an intelligent data storage system based on piezoelectric sensors / memristors will be described in detail below with reference to the accompanying drawings.

[0039] as attached figure 1 As shown in the basic circuit diagram of the piezoelectric sensor, an additional external circuit is designed through components such as resistors, inductors and triodes. In the process of testing the pressure generating sheet, it is found that the electrical signal converted from the mechanical signal cannot have any effect under the condition of direct external load. The study found that due to the large leakage current of the pressure power generation sheet, only voltage exists externally. If the load needs to be connected, there must be enough current, so the external circuit is designed to reduce its leakage current.

Abstract

The invention discloses an intelligent data storage system based on a piezoelectric sensor-memristor, which integrates a piezoelectric sensor and a memristor device to convert a pressure signal into an electrical signal, thereby driving the memristor device and completing data recording with storage. A protection circuit is designed at the output port of the pressure generating chip, so that the external mechanical signal will not break down the memristive device. When the intelligent data storage system is working, no external voltage is needed no matter recording, converting or erasing. The invention innovatively integrates the piezoelectric sensor and the memristor into an intelligent data storage system. The piezoelectric sensor and the memristor are combined to form a preliminary application. After many tests, the system has high stability and can Adapt to a variety of environments, broad application prospects.

Description

technical field [0001] The invention relates to the application field of nanomaterials and the technical field of microelectronics, in particular to an intelligent data storage system based on a piezoelectric sensor / memristor. Background technique [0002] As a technological science that has developed rapidly in recent years, artificial intelligence is changing human life at an unprecedented speed. Compared with humans, artificial intelligence devices have better computing speed, storage space, reliability and durability, and artificial intelligence has gradually entered all aspects of human life. [0003] Today's society is a rapidly developing society, and people's demand for data storage is growing rapidly. Processing large amounts of information places higher demands on the performance of existing storage devices. The current mainstream non-volatile storage technologies on the market are gradually encountering development bottlenecks in terms of size, power consumption...
