Soft Adaptive Mechanical Metamaterials

Frontiers in Robotics and AI, 2021
Soft materials are inherently flexible and make suitable candidates for soft robots intended for specific tasks that would otherwise not be achievable (e.g., smart grips capable of picking up objects without prior knowledge of their stiffness). Moreover,

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Farmers' land‐use decision‐making: A dynamical modelling approach that integrates qualitative knowledge about social norms into a quantitative model

People and Nature, 2023
The concept of the homo oeconomicus is often used to model human behaviour in economic contexts. However, other factors like tradition or the preference to comply with social norms can play a role in decision‐making processes.

Stress‐guided photo‐programming of cholesteric liquid crystal elastomers for 2D‐to‐3D shape–color information encoding

Responsive Materials, EarlyView.
We reported a stress‐guided photo‐programming strategy that enables cholesteric liquid crystal elastomers (CLCEs) to achieve synchronous 3D shape morphing and structural color evolution from a single 2D film. Abstract Flexible materials with dynamic structural colors have attracted considerable interest for multilevel information interaction, showing ...

Towards a statistical theory of solid dry friction

, 1997
Wearless dry friction of an elastic block of weight N, driven by an external force F over a rigid substrate, is investigated. The slider and substrate surfaces are both microscopically rough, interacting via a repulsive potential that depends on the ...

Four‐Dimensional Generalization of Ensemble Singular Vector: Formulation and Experiments With the Lorenz 96 Model

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Motivated by the need to extend sensitivity analysis beyond spatial variations to include temporal evolution, we propose a four‐dimensional generalization to the ensemble singular vector approach, termed 4DEnSV. This generalization enables user‐defined norms that flexibly target spatiotemporal evolutions of interest.

Bistability and nonequilibrium transitions in the optically polarized system of cavity polaritons under nanosecond-long resonant excitation

, 2011
The polarization dependence of nonequilibrium transitions in a multistable cavity-polariton system is studied under a nanosecond long resonant optical excitation at the normal and magic angle incidences with various polarizations of the pump beam.

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This work uses topology optimization to design unit cells for mechanical metamaterials with a prescribed nonlinear stress–strain response. The framework adds contact and postbuckling modeling to synthesize microstructures for three highly nonlinear responses, including pseudoductile behavior, monostable with snap‐through buckling, and bistable ...

Tristability in a non-equilibrium double-quantum-dot in Kondo regime

, 2002
Electron tunneling through a non-equilibrium double quantum dot in the Kondo regime is studied. In the region of negative differential resistance, it is shown that this system possesses a complex response to the applied potential characterized by a ...
