Summary: This paper presents a custom-made graphite-based piezoresistive strain sensor with gecko foot-inspired macroscopic features realized using Velcro tape on Ecoflex substrate. The sensor shows improved performance even at low strain values and has a high gauge factor (>100) for very low strain values. The piezoresistive behavior of strain sensors is influenced by factors such as the supporting elastic medium, architecture of the strain sensor, material properties, strain rate, and deformation sequence.

Summary: One of the key challenges for adapting the roll-to-roll (R2R) process to flexible electronics production is to achieve tight registration requirements between layers. This study proposed a precise registration control method for an R2R screen printing system based on registration error analysis, passive compensation, and active compensation. The evaluation of registration error factors and the application of passive and active compensation resulted in accurate and precise registration, making the system suitable for manufacturing flexible electronic devices.

Summary: A facile approach for manufacturing cellulose paper-based strain sensors with Ni/multi-walled carbon nanotube (MWCNT) composites using roll stamping technology is proposed in this study, enabling the fabrication of stable sensing structures. The rheological properties of the composites revealed shear thinning and thixotropic behavior, allowing for fine printing of the sensing electrodes. The shape of the printed patterns significantly influenced the strain-sensing performance, with the Ni/MWCNT composite-based strain sensor exhibiting a higher gauge factor of 13.9 and high stability.
