Dual‐Mode Gripper With Suction and Shape‐Adaptive Freezing Grasps
Advanced Robotics Research, EarlyView.This study presents a dual‐mode robotic gripper that combines vacuum suction with a shape‐adaptive freezing grasp. The freezing mode uses a compliant rubber membrane, a sprayed water layer, and dry‐ice powder to generate ice‐mediated adhesion while conforming to complex geometries.

An Autoparametric System with Dry-friction
, 2008 We consider an autoparametric system containing a dry-friction oscillator characterised by a small parameter. One interesting aspect of the analysis of the semitrivial (planar) solution is the possibility of calculating the boundary value for the ...

The use of a non-classical friction law in finite-element analysis of contact problems [PDF]
, 1983 Bibliography: leaves 82-84.In this thesis a description is given of the numerical treatment of contact problems in elasticity. Frictional effects on the contact surface are modelled by using a nonlocal, nonlinear friction law.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics
Advanced Science, EarlyView.The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Dry Friction Discontinuous Computational Algorithms [PDF]
, 2014 The design of high position accuracy servo mechanisms (such as an aircraft primary command EHA), involves the deep knowledge of their behaviour, markedly affected by the Coulomb friction.

Advanced Science, EarlyView.Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...

Influence of delayed excitation on vibrations of turbine blades couple
Applied and Computational Mechanics, 2013 In the presented paper, the computational model of the turbine blade couple is investigated with the main attention to the influence two harmonic excitation forces, having the same frequency and amplitude but with moderate delay in time.

Advanced Science, EarlyView.ABSTRACT Current clinical approaches for knee cartilage repair are often limited by hypertrophy and fibrosis in the regenerated tissues. A decellularized tissue‐engineered hyaline cartilage graft (dLhCG), composed of a type II collagen‐based extracellular matrix, has been developed to overcome this limitation.
