Scalable High‐Force Zipping Electrostatic Actuators
Advanced Intelligent Systems, Volume 8, Issue 5, May 2026.An electrostatic actuator architecture is presented that combines high energy density with forces and strokes suited for wearable soft robotics. By folding patterned thin films into a scalable honeycomb of zipping units, performance becomes tunable through series–parallel design, achieving over 40 N and 28 J/kg.

Journal of Pineal Research, Volume 78, Issue 3, May 2026.ABSTRACT Disuse osteoporosis, a consequence of prolonged mechanical unloading, is characterized by bone loss and elevated fracture susceptibility. Although melatonin exhibits bone‑anabolic properties, its mechanistic role in the context of mechanical unloading remains elusive.

Natural frequency of beams with embedded piezoelectric sensors and actuators
, 2007 A mathematical model is developed to study the natural frequency of beams with embedded piezoelectric sensors and actuators. The piezoelectric sensors/actuators in a non-piezoelectric matrix (host beam) are analyzed as two inhomogeneity problems by using

, 2001 In this paper we study systems in which the system operator, $A$, has a Riesz basis of (generalized) eigenvectors. We show that this class is subset of the class of spectral operators as studied by Dunford and Schwartz.

Non-uniform Euler-Bernoulli beams´ natural frequencies
Ingeniería e Investigación, 2011 This paper has studied the problem of natural frequencies for Euler-Bernoulli beams having non-uniform cross-section. The numerically-obtained solutions were compared to asymptotic solutions obtained by the Wentzel-Kramers-Brillouin (WKB) method. It was established that WKB formula precision was higher than 3% for high frequencies (≥ 4 mode).

Optimum vibrating beams with stress and deflection constraints [PDF]
The fundamental frequency of vibration of an Euler-Bernoulli or a Timoshenko beam of a specified constant volume is maximized subject to the constraint that under a prescribed loading the maximum stress or maximum deflection at any point along the beam ...

Numerical Fractional Calculus Framework for Nonlocal Euler–Bernoulli Beam Deflection Analysis
Fractal and FractionalIn this study, the bending behavior of beams is investigated using the fractional Euler–Bernoulli beam model. This model is developed based on fractional calculus, particularly employing the Riesz–Caputo derivatives, and is capable of accurately ...
