Advanced Science, EarlyView.This study proposes a piezoelectric interface modification strategy to amplify the piezoionic effect. The piezoelectric interface generates an intrinsic electric field, which not only drives rapid ion migration but also concentrates polarized ions on the interface. The flexible sensor delivers superior performance, such as a quick response rate, strong

Well-posedness and Stability for Interconnection Structures of Port-Hamiltonian Type
, 2019 We consider networks of infinite-dimensional port-Hamiltonian systems $\mathfrak{S}_i$ on one-dimensional spatial domains. These subsystems of port-Hamiltonian type are interconnected via boundary control and observation and are allowed to be of distinct

Scalable High‐Force Zipping Electrostatic Actuators
Advanced Intelligent Systems, EarlyView.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.

A Numerical Method of the Euler-Bernoulli Beam with Optimal Local Kelvin-Voigt Damping
Journal of Applied Mathematics, 2014 This paper deals with the numerical approximation problem of the optimal control problem governed by the Euler-Bernoulli beam equation with local Kelvin-Voigt damping, which is a nonlinear coefficient control problem with control constraints. The goal of

A novel director-based Bernoulli–Euler beam finite element in absolute nodal coordinate formulation free of geometric singularities [PDF]
Mechanical Sciences, 2013 A three-dimensional nonlinear finite element for thin beams is proposed within the absolute nodal coordinate formulation (ANCF). The deformation of the element is described by means of displacement vector, axial slope and axial rotation parameter per ...

Fractal Continuum Calculus of Functions on Euler-Bernoulli Beam
Fractal and Fractional, 2022 A new approach for solving the fractal Euler-Bernoulli beam equation is proposed. The mapping of fractal problems in non-differentiable fractals into the corresponding problems for the fractal continuum applying the fractal continuum calculus (FdH3-CC ...

, 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.

Timoshenko Beam Model for Lateral Vibration of Liquid-Phase Microcantilever-Based Sensors [PDF]
, 2013 Dynamic-mode microcantilever-based devices are potentially well suited to biological and chemical sensing applications. However, when these applications involve liquid-phase detection, fluid-induced dissipative forces can significantly impair device ...
