Description

Technical Field

[0001] The present invention relates to the field of ultra-micro technology, and in particular to an electrically driven carbon-based nanometer current controller. Background Art

[0002] Electric drive current controller refers to an electronic component that controls its working state or output characteristics through current. Such devices are widely used in power management, signal amplification, switch control and other fields.

[0003] The working principle of the electric drive current controller mainly involves two aspects: current control and voltage control. Among them, current control mainly controls the load by adjusting the current in the circuit. Specifically, the circuit can be controlled by changing the current of the alternating current. The alternating current is modulated by power electronic devices (such as thyristors, IGBTs, etc.), thereby changing the effective value of the current. Voltage control controls the circuit by adjusting the voltage in the circuit. The voltage controller receives the input voltage and output voltage signals and generates a control error signal by comparing the difference between the two signals, thereby adjusting the output voltage. The voltage control mode stabilizes the output by monitoring the output voltage and adjusting the PWM duty cycle, which is suitable for loads that require precise voltage control. However, due to the limitations of traditional electric drive current controllers in miniaturization, it is difficult to achieve more efficient signal processing, energy conversion and material transmission.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0019] The present invention provides an electrically driven carbon-based nanometer flow controller. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Since the beginning of this century, the research and application of low-dimensional materials have made remarkable progress, especially carbon-based nanomaterials such as carbon nanotubes and graphene, which have become the cornerstone of the development of nanotechnology due to their excellent electrical, thermal and mechanical properties. This progress has created unprecedented opportunities for the design and manufacture of micro- and nanoscale devices, especially in the field of nanoelectromechanical systems, which combine the design concept of microelectromechanical systems with the scale effect of nanomaterials to overcome the limitations of traditional microelectromechanical systems in miniaturization, thereby achieving more efficient signal processing, energy conversion and material transmission.

[0021] Based on this, an embodiment of the present invention provides an electrically driven carbon-based nanometer flow controller, which includes a path control substrate 1, an input fluid pump group 2, an output fluid pump group 3, a channel 4, a self-shrinking deformable body 5 and a charged body 6;

[0022] The path regulation substrate 1 includes a nano substrate 11 and a nano base block 12, and the nano base block 12 is fixedly connected to one side of the nano substrate 11; the input fluid pump group 2 and the output fluid pump group 3 are respectively located on the two sides of the path regulation substrate 1 away from the nano base block 12, the input fluid pump group 2 includes a plurality of input fluid pumps, which are responsible for introducing the liquid or gas to be treated into the system through the nano channel and providing initial flow power, and the output fluid pump group 3 includes a plurality of output fluid pumps, which are paired with the input fluid pump and are used to output the fluid from the system; the two ends of the channel 4 are respectively connected to the input fluid pump group 2 and the output fluid pump group 3 in the working state, and the self-contracting deformable body 5 includes a nano spring 51, one end of the nano spring 51 is fixedly connected to the nano base block 12, and the other end is placed with the charged body 6 and fixedly connected to the channel 4, and the nano spring 51 is used to move the channel 4 to a specific position and can be restored to the initial position.

[0023] The working principle of the electrically driven carbon-based nano-current controller provided by the embodiment of the present invention is as follows: in the initial state, the nano-spring 51 and the channel 4 are stably attached to the nano-substrate 11 due to the interlayer van der Waals force; in the working state, a control electric field 7 is applied, and the charged body 6 is acted upon by the electric field force, driving the nano-spring 51 and the channel 4 to move along the direction of the nano-substrate 11 (laterally), and the channel 4 is stabilized to the target position under the combined action of the electric field force, the elongation force of the nano-spring 51 and the intermolecular force, and a group of input fluid pumps and the output fluid pump in the input fluid pump group 2 and the output fluid pump group 3 are connected to generate a passage, and the electrically driven carbon-based nano-current controller outputs fluid outwardly; when the electric field is unloaded, the nano-spring 51 and the channel 4 are acted upon by the internal force of the nano-spring 51 and the van der Waals force of the nano-substrate 11 to move back in the opposite direction of the nano-substrate 11 (opposite to the movement direction of the channel in the working state above), the channel is cut off, and the electrically driven carbon-based nano-current controller is restored to the initial state, thereby ensuring the repeatability of its movement.

[0024] The electrically driven carbon-based nanometer flow controller provided in the embodiment of the present invention can realize multiple inputs and selective single output of fluids, and can realize fluid screening and outflow control by adjusting the size and direction of the electric field.

[0025] In some embodiments, the electrically driven carbon-based nano-flow controller further includes a nano-constraint 8 for constraining the lateral movement of the nano-spring and the channel, and the nano-constraint 8 is connected to the nano-base 11 .

[0026] In some preferred embodiments, the nano-constraint member 8 comprises a first nano-constraint sheet 81, a second nano-constraint sheet 82 and a third nano-constraint sheet 83, one end of the first nano-constraint sheet 81 is connected to the nano-base block 12, and the other end is connected to the second nano-constraint sheet 82, one end of the third nano-constraint sheet 83 is connected to an end of the nano-base block 12 away from the first nano-constraint sheet 81, and the other end is connected to an end of the second nano-constraint sheet 82 away from the first nano-constraint sheet 81. That is, the two ends of the nano-base block 12 are respectively connected to one end of the first nano-constraint sheet 81 and the third nano-constraint sheet 83, and the other ends of the first nano-constraint sheet 81 and the third nano-constraint sheet 83 are both connected to the second nano-constraint sheet 82.

[0027] The nano-constraint 8 can limit the movement of the nano-spring 51 and the channel 4 to improve the operating stability of the electrically driven carbon-based nano-flow controller; limit the maximum deformation of the nano-spring 51 to prevent the nano-spring 51 from exceeding the deformation limit and affecting the service life of the electrically driven carbon-based nano-flow controller.

[0028] In some embodiments, the materials of the nano substrate 11 and the nano spring 51 are both graphene.

[0029] The materials of the nanospring 51 and the nanosubstrate 11 are both graphene. The nanosubstrate 11 is used to support the movement of the nanospring 51 and the channel 4 and provide a super-lubricated movement environment. At the same time, it can make the nanospring 51 return to its original state through the van der Waals force between the graphenes, and maintain the operating state of the nanospring 51 and the channel 4 through the van der Waals force, that is, the nanospring 51 and the channel 4 are both attached to the graphene substrate and slide, thereby improving the operating stability of the electrically driven carbon-based nano-flow controller.

[0030] Graphene has high ductility and can be attached to the surface of other materials, better adapting to the shape of the nano substrate 11 and connecting the input fluid pump group 2 and the output fluid pump group 3 in series to form a complex path.

[0031] In some embodiments, the nano spring 51 is a graphene paper-kirigami structure. The nano spring 51 can be obtained by nano-paper-kirigami technology, and this structure can enable the nano spring 51 to achieve large deformation.

[0032] In some embodiments, the fluid pumps of the input fluid pump group 2 and the output fluid pump group 3 are both carbon nanotubes, which are used to connect the input / output fluids outside the system. Carbon nanotubes, as natural channels at the nanoscale, can significantly improve the efficiency of fluid transmission and the corrosion resistance of the system.

[0033] In some embodiments, the charged body 6 is a charged carbon atom, which is displaced under the action of an electric field and causes the nanospring to deform.

[0034] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments, and are only for illustrating the present invention but not limiting the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0035] It should be understood that the application of the present invention is not limited to the above examples.
