Flexible electronic technology is likely to bring about a revolution among industrial application in the future.In recent years,many research institutes and universities have conducted research on it,leading to the significant increment of research paper in this field.Since the unique advantage of additive manufacturing of 3D printing technology is regarded as a processing technology with great potential,the British Economic Journal ranked it with information technology,which would promote the industrial revolution.This thesis conducts research on the combination of flexible electronic technology and 3D printing technology,and studies the processing method of flexible electronic components based on direct ink writing,which plays the advantage of additive manufacturing of 3D printing technology,and furthermore,makes up the downside of conventional technic of processing components based on flexible foundation.Through reading a large number of related literatures,this paper has conducted a detailed research on the current research status of flexible electronic devices and 3D printing technologies at home and abroad,analyzed a variety of existing electronic device processing methods,and the challenges of these methods in manufacturing flexible devices.Combined with the processing idea of 3D printed additive manufacturing,this paper puts forward the relevant experimental system,control method and application research for the integrated manufacturing of flexible nano sensor devices.This is of great importance for meeting the requirements of future flexible electronic devices and wearable devices.In order to realize the integrated manufacturing of flexible devices,the hardware structure of the direct write 3D printing flexible electronic device system is designed first,and the structure of dual print heads alternating printing is developed.This structure can realize the composite printing of two kinds of materials,the system has great flexibility,and also can effectively expand the field of application of the system.At the same time,for the system to build a UV curing device and the temperature adjustable thermal curing device,the need for follow-up curing material can be based on actual needs and choose the right way.In view of the demand of integrated printing control system,this article designs and optimizes the control program of the debugging system.The main parameters affecting system stability and movement accuracy are analyzed.The results show that the quality factor of the system can be over 95%by adjusting PID parameters of the system.At this point the system can be stable operation,and the system error is small,high positioning accuracy.On the basis of this,the software has been developed for the second time,a friendly user interface has been developed,a program for quickly preparing printing paths based on two-dimensional graphics and fast slicing software for three-dimensional structures has been prepared.The two software processing ideas are based on print needs to print the path into the machine can identify the G code,the use of platform motion control program calls the G code of the print path to complete the commercial 3D printer to complete the task and part of the existing System difficult to achieve the liquid conductive paste printing work.Finally,the experimental verification is done by using the system built in this paper.Experiments were conducted on different printed materials,such as silver nanoparticles,carbon nanomaterials,and polymer materials such as silicone gum and PDMS.This paper focuses on the rheological properties of liquid slurries suitable for printing in this system,summarizes the relationship between print linewidth and print speed,and lays the foundation for the realization of flexible device manufacturing.The system is used to print a number of flexible electronic devices,as well as three-dimensional structures such as a plurality of microfluidic pipelines.The experimental application tested the printed electronics for performance,enabling the use of electromagnetic induction coils,infrared sensors,double-layer flex circuits and gloves that can be used to identify gestures with fully printed flexible stress sensors.
