The application discloses a memristor, a method for preparing the same and an artificial synapse device, and the memristor comprises a glass cone and a polyelectrolyte structure on the inner wall of the glass cone; the glass cone has a first end opening and a second end opening arranged oppositely, the diameter of the first end opening is smaller than that of the second end opening, and the polyelectrolyte structure is located on the inner wall of the first end opening. Thus, the memristor has low power consumption of a picojoule level, a low working potential and high efficiency. When a pulse potential stimulus is applied, the memristor can generate a double-pulse facilitation and a double-pulse inhibition effect similar to a neuron synapse, and due to the existence of an ion effect, the effective regulation of the plasticity of the system can be realized. Further, the signal transduction function based on ions can be realized by being combined with a micro-injection system. In addition, the memristor has excellent stability and designability and the like.

The application provides an ultrasonic plasticizing micro injection molding equipment for producing a micro cantilever beam and a use method, relates to ultrasonic plasticizing molding, and comprises a movable mold fixing plate, a fixed mold fixing plate, a base plate, a protective sleeve, a mold assembly and an ultrasonic head. The application utilizes the base plate to form a centering part, the outer profile of the centering part and the inner profile of the protective sleeve are both inclined surfaces, the centering part and the protective sleeve are centered by utilizing the principle of inclined surface fitting, the blanking pipeline formed by the protective sleeve is fitted with the injection hole surface of the mold assembly to realize the centering of the protective sleeve and the mold assembly, the centering efficiency in the ultrasonic plasticizing micro injection process is improved, and the centering difficulty is reduced. Meanwhile, the mold core unit is also improved, the mold core base and the micro structure cavity are designed in a split mode, different stiffness micro structures are conveniently generated, and the forming length of the micro cantilever beam is increased by means of two side feeding.
