    in

    What the study found The study found that a two-step composite hydrogel design can separate mechanical and electrical optimization in a strain-sensing material. The resulting PAAm@PPy hydrogel combined soft-tissue-like stiffness, high stretchability, low mechanical hysteresis, and electrical conductivity. Why the authors say this matters The authors say the work establishes a conductive hydrogel design paradigm…

    What the study found The study found that the rigidity of many origami structures can be controlled by making selected facets planar or allowing them to relax. The authors also report that geometry, topology, and facet-selection rules affect how many degrees of freedom these structures have and when rigidity changes occur. Why the authors say…
