柔软的、可拉伸的传感器，例如人造皮肤或触觉传感器，由于材料顺应性低，对于许多软机器人应用是有吸引力的。导电聚合物是许多软传感器的必要组成部分，这项工作提出了3D可打印导电聚合物复合材料的机电特性。使用基于数字光处理（DLP）的3D打印机3D打印狗骨形状的样品以进行表征。3D可打印树脂由单体、交联剂、导电纳米填料和光引发剂组成。在两个轨道中进行表征。首先，两种不同的交联剂的效果进行了研究与不同的组合物和第二，导电纳米填料的浓度的影响进行了探索。通过参考前人的研究选择了交联剂，并利用碳纳米管（CNTs）作为导电纳米填料。样品是3D打印的，并使用机电测试装置进行表征。为了证明3D打印软机器人的实用性，3D打印了由导电和非导电树脂组成的基于电容的操纵杆传感器。
Soft, stretchable sensors, such as artificial skins or tactile sensors, are attractive for numerous soft robotic applications due to the low material compliance. Conductive polymers are a necessary component of many soft sensors, and this work presents the electromechanical characterization of 3D-printable conductive polymer composites. Dog-bone shaped samples were 3D printed using a digital light processing (DLP)-based 3D printer for characterization. The 3D printable resin consists of monomer, crosslinker, conductive nano-filler, and a photo-initiator. The characterization was performed in two tracks. First, the effect of two different crosslinkers was investigated with different compositions and second, the effect of concentration of conductive nano-fillers was explored. Crosslinkers were chosen by referring to previous studies, and carbon nanotubes (CNTs) were utilized as conductive nano-fillers. The samples were 3D printed and characterized using an electromechanical test setup. To demonstrate utility for 3D printed soft robotics, a capacitance-based joystick sensor composed of both conductive and non-conductive resins was 3D printed.
