最近，喷墨印刷技术作为在聚合物基底上生产低成本大面积电子器件、传感器和天线的方法受到越来越多的关注。该技术依赖于印刷技术将电功能材料存款到聚合物基底上以制造电子部件或传感元件。在本文中，我们采用了喷墨印刷技术的开发和表征的聚合物基板上的薄膜，旨在提供设计考虑的优化应变传感器或印刷电子获得喷墨印刷。在聚酰亚胺基底、水基导电聚合物PEDOT：PSS和银纳米颗粒油墨上测试两种油墨。他们的传感能力进行了研究，在拉伸条件下和各种应变的历史（应变斜坡;循环加载-卸载测试;应用恒定应变在较长的时间），旨在突出电响应，施加应变，时间和机械历史之间的相关性。此外，在类似的应变历史下，基板的机械粘弹性响应进行了研究，解释结果在光的基板变形特性和评估其影响。(C)© 2016 Elsevier B.

Recently, inkjet printing technology has received growing attention as a method to produce low-cost large-area electronics, sensors, and antennas on polymer substrates. This technology relies on printing techniques to deposit electrically functional materials onto polymer substrates to fabricate electronic components or sensing elements. In this paper, we applied an inkjet printed technology for the development and characterization of films on a polymer substrate aiming at giving design considerations for the optimization of strain sensors or printed electronics obtained by inkjet printing. Two inks were tested over a polyimide substrate, a water-based conductive polymer, PEDOT:PSS, and a silver nanoparticles ink. Their sensing capabilities were investigated under tensile conditions and various strain histories (strain ramp; cyclic loading-unloading tests; application of constant strain over prolonged time) aiming at highlighting the correlation between electrical response, applied strain, time and mechanical histories. Furthermore, the mechanical viscoelastic response of the substrate was investigated under similar strain histories interpreting the results at the light of the substrate deformational characteristics and evaluating its influence.
