Architected Load Paths Enable Stiffening and Motion Programming in Soft Pneumatic Actuators
Advanced Science, EarlyView.A single MARS template introduces an architected reinforcement strategy for programmable soft pneumatic actuators through internal structural organization and selective beam removal. This monolithic architecture enables deformation reconfiguration from continuous bending to joint‐like articulation and torsional motion, allowing one compliant platform ...

Nodal forces in the analysis of the ultimate torsional moment for rectangular beams
, 1974 Equilibrium and work (energy) methods are reviewed for analysis of the ultimate torsional moment of rectangular under-reinforced concrete beams. In analogy with the yield-line theory for slabs, it is shown that the equilibrium method can be brought to ...

Shear‐Mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals
Advanced Science, EarlyView.Periodic shear‐induced electric current measurements are reported on two archetypic ferroelectric nematic liquid crystal compounds. From the temperature, frequency and shear angle dependent results of the first and second harmonic current signals together with temperature and oscillatory rheology measurements, the effective piezoelectric coupling ...

Advanced Science, EarlyView.Inspired by the insect campaniform sensillum, a heterogeneous bilayer strain sensor is developed based on a unique impedance mismatch and three‐dimensional structural dynamic percolation strategy. The sensor enables real‐time multi‐joint teleoperation of three joints and the gripper using a six‐degree‐of‐freedom robotic‐arm platform.
