Flexible electrodes are crucial for the widespread application of flexible electronics. Flexible stretchable electrodes are a research hotspot for finding a solution for the inability of flexible electrodes to withstand large deformations. In this study, the suitability of silicone rubber (Ecoflex), carbon nanotube (CNT), and carbon fiber (CF) composite materials for flexible devices and their ratios were evaluated for the first time. 3D-printed electrodes based on fractal structures with tensile insensitivity and high linearity were prepared to achieve integrated stretching of flexible devices. To demonstrate the benefits and impact of fractal structures on electrode performance, we fabricated flexible stretchable electrodes…

Using 3D printing to manufacture shape memory polymers (SMPs) becomes popular, since the technique endows SMPs the ability to shape into desired structures according to their applications. Among various types of SMPs, epoxy-based shape memory polymer and their composites are known for their high modulus and strength. However, limited by their rheological behavior, it is still hard to prepare high-quality printable epoxy materials. Here, by carefully tuning of rheological properties, we can prepare printable ink showing good shape retention, excellent mechanical performances below and above the glass transition temperature of epoxy, as well as good shape memory effect. The prepared…

Information from the brain travels back and forth along peripheral nerves in the form of electrical impulses generated by neurons and these impulses have repetitive patterns. Schwann cells in peripheral nerves receive molecular signals from axons to coordinate the process of myelination. There is evidence, however, that non-molecular signals play an important role in myelination in the form of patterned electrical impulses generated by neuronal activity. The role of patterned electrical impulses has been investigated in the literature using co-cultures of neurons and myelinating cells. The co-culturing method, however, prevents the uncoupling of the direct effect of patterned electrical impulses…
