Abstract:
As a new rapid additive manufacturing technology that has emerged in recent years, 3D printing technology can realize the precise manufacturing of complex and flexible sensor structures. In this study, a sensor was fabricated by injecting silver nanowires (AgNWs) ethanol solution into stretchable polydimethylsiloxane (PDMS). The substrate was used in two design configurations through a 3D printing template method, i.e. “straight” and “wave”. Compared to the straight sensor, the structural design of the wave sensor could increase the stretch range and sensitivity. In particular, the stretch range increased by 26.1% and the sensitivity improved by 96.0%. The stretchable sensor was successfully applied in pronunciation recognition and gait detection. Therefore, the stretchable sensor is also expected to be further used in fields such as foldable phones and wearable physiological signal sensors.Keywords:

Influencing factors on electric resistance of electrically conductive ink were analyzed.A screen printing process was designed and bar codes were printed on different substrates using electrically conductive ink.The prints were dried and the electric resistance of bar codes of electrically conductive ink was tested,processed and analyzed.The results showed that the bar code resistances of electrically conductive ink change with different screen lines,therefore,bar code printed by electrically conductive ink can be another effective way for package anti-counterfeit printing.

At condition temperature 20~25℃ and humidity 60%~65%, the author using IGT printability tester(model AIC2-5) made a experimental study of printing ink′s absorbing characteristic to common printing paper-glazed printing paper and coated art paper.The results show that the printing press assuring best printing ink absorbency of paper is dissimilar at different printing speed conditions,the glazed printing paper′s printing ink absorbency is more sensitive than the coated art paper to printing press,and at the same condition,the coated art paper press′s demand is lower than the glazed printing paper.

A process development for stretchable silicon electronics encapsulated in a layer of polydimethylsiloxane is presented. Stretchability is achieved by segmenting the normally rigid silicon substrate into small islands (<2×2 mm 2 ) and connecting these by flexible metal interconnects. The metal interconnects have a mesh shape providing stretchability and improved reliability. The mesh-shaped interconnects have been simulated and measured as free standing before being integrated in the final stretchable system design. PDMS (polydimethylsiloxane) encapsulation using either Elastosil or Sylgard, having good chemical and mechanical resistance, provides protection of the final system but it also helps during fabrication. The fabricated samples (ID array silicon islands with mesh interconnects embedded in Elastosil) have been mechanically and electrically tested and provide reversible stretchability to around 100%.

Three dimensional (3D) printing consists of sequential printing of various layers of materials on top of each other to create complex structures with different functionalities. Stereolithography (SLA) consists in the sequential exposure of a photochemical polymer. This way, each layer of the final 3D object is exposed by a ultra violet laser which crosslinks the photopolymer to convert it into a non-soluble material. In terms of disadvantages, although SLA can produce very high quality prototypes, the fragility and necessity of post curing of the 3D printed objects are still issues that have not been solved for this printing method. Polymeric materials with low melting points are some of the most widely used materials in the area of 3D printed electronics due to the low cost, chemical strength, and low processing costs. Hybrid 3D printed electronics has become one of the most researched topics in the area of flexible and stretchable electronics.

With the development of the green inks, UV ink has been applicated wider and wider in the printing, packaging and the electronics industry. Based on the UV inks and screen printing process, this paper has investigated the influnce of mesh count, screen ruling, printing materials and ink viscosity on print quality by measuring the printing dot gain experimentally. The results show that the higher mesh count and more smooth printing material can induce the better dot, tone reproduction and higher printing precision. The more serious dot gain and the worse tone reproduction will induced by lower ink viscosity. The higher screen ruling cause the bigger dot gain value. Bigger rate of mesh count with screening ruling can reduce the moire phenomena.

Inkjet printing polydimethylsiloxane (PDMS) has received wide interest in the field of additive manufacturing for printing flexible wearable electronics. Before depositing the PDMS on the target substrate with desired pattern, the PDMS ink must be ejected in a stable manner. One of the problems that affects the jetting quality is the satellite droplet coming with the dominate droplet during the printing process, which is known as the satellite effect. In this paper, we investigated the possibility of stable jetting of PDMS ink without the satellite effect. The cartridges with 10pl (FUJI Dimatix DMP-2850) were used to jet PDMS ink. The solvent for the preparation of PDMS ink was decane combined with toluene as a co-solvent for adjusting the physical properties of the PDMS ink. The generation of stable PDMS ink droplets was achieved by optimizing the mixture solvent of PDMS ink and the adjustment of the printing voltage waveform, which indicated the inkjet printing of PDMS is a promising method for fabricating flexible wearable electronics.

A procedure is described for making layer-to-layer interconnections in polydimethylsiloxane (PDMS) microfluidic devices. Thin (∼50 μm) perforated PDMS membranes are bonded to thicker (0.1 cm or more) PDMS slabs by means of thermally cured PDMS prepolymer to form a three-dimensional (3D) channel structure, which may contain channel or valve arrays that can pass over and under one another. Devices containing as many as two slabs and three perforated membranes are demonstrated. We also present 3D PDMS microfluidic devices for display and for liquid dispensing.
