Physical Intelligence in Small‐Scale Robots and Machines

Advanced Materials, Volume 38, Issue 12, 25 February 2026.
“Physical intelligence” (PI) empowers biological organisms and artificial machines, especially at the small scales, to perceive, adapt, and even reshape their complex, dynamic, and unstructured operation environments. This review summarizes recent milestones and future directions of PI in small‐scale robots and machines.

Using stability analysis of discrete elastic systems to study the buckling of nanostructures

Archives of Mechanics, 2012
Stubility/instability criteria of discrete elastic systems are used to study the buckling of nanostructures. The deformation of nanostructures is simulated by solving the nonlinear equations of molecular mechanics.

Bifurcations of a simplified buckling problem and the effect of discretizations

manuscripta mathematica, 1991
The author gives a detailed description of bifurcations on the trivial solution branch \(\{\) (0,\(\lambda\)); \(\lambda\in {\mathbb{R}}\}\) of a simplified buckling problem \(\Delta u+\lambda \sin u=0\) in \(\Omega =[0,1]\times [0,1]\), \(u=0\) on \(\partial \Omega\).

Free-Vibration and Buckling Analyses of Beams using Kriging-Based Timoshenko Beam Elements with the Discrete Shear Gap Technique

Civil Engineering Dimension
A family of locking-free Kriging-based Timoshenko beam elements with a new implementation of the discrete shear gap technique was recently developed (referred to as K-beam-DSG1 elements). Performance of the K-beam-DSG1 elements has been shown to be very

The Formation and Coarsening of the Concertina Pattern

, 2011
The concertina is a magnetization pattern in elongated thin-film elements of a soft material. It is a ubiquitous domain pattern that occurs in the process of magnetization reversal in direction of the long axis of the small element.
