Summary: Soft vibrotactile devices are important for future developments of multifunctional electronic skin technologies, but currently lack overall performance, sensing-actuation feedback, control, and mechanical compliance. This study presents soft haptic electromagnetic actuators that address these issues by utilizing intrinsically stretchable conductors, pressure-sensitive conductive foams, and soft magnetic composites.

Summary: This study demonstrates the potential of TEMPO-oxidized cellulose nanofibrils (T-CNF)/poly(vinyl alcohol) (PVA) coatings to develop functionalized membranes with outstanding antifouling performance and stability in the ultrafiltration regime. The coated membranes showed nano-textured surface, altered surface charge, and improved mechanical properties compared to the original substrate. Additionally, the coated membranes exhibited charge specific adsorption and rejection driven by electrostatic interaction and size exclusion mechanisms, leading to reduced fouling when exposed to BSA and E. coli.

Summary: A novel biomaterial ink composed of regenerated silk fibroin and TEMPO-oxidized bacterial cellulose nanofibrils has been developed for 3D printing lung tissue scaffolds. The addition of OBC nanofibrils increased ink viscosity and improved scaffold shape fidelity, with optimal printing parameters identified as 0.3 bar printing pressure, 45 mm/s printing speed, and 410 μm nozzle diameter. OBC nanofibrils were aligned along print lines, guiding the orientation of lung epithelial stem cells and maintaining their proliferation ability and epithelial phenotype after 7 days of culture.

Summary: Due to irreversible aggregation, achieving nanoscale redispersion of cellulose nanofibrils has been challenging. This study proposed a re-watering strategy to achieve nanoscale redispersion of oven-dried TOCN in water. Water wetting-up was effective in achieving high redispersion rates, and the addition of sodium lignosulfonate further improved the redispersion rate. The redispersed TOCN exhibited no significant difference in mechanical properties and could be used as a proppant for fracturing fluids to improve their stability.
