Finite element reduced order models for nonlinear vibrations of piezoelectric layered beams with applications to NEMS [PDF]
, 2012 This article presents a finite element reduced order model for the nonlinear vibrations of piezoelectric layered beams with application to NEMS. In this model, the geometrical nonlinearities are taken into account through a von Kármán nonlinear strain ...

Advanced Materials Technologies, EarlyView.A flexible pressure sensor utilizing a 3D dual‐pore polyurethane structure is developed to overcome the intrinsic trade‐off between sensitivity and linearity. By inducing sequential buckling through distinct pore sizes and shapes, the device achieves highly linear and sensitive responses across a wide pressure range.

Nonlinear Vibrations and Chaos of an Arch with Small Rise [PDF]
, 1996 Nonlinear free and forced vibrations of an arch with small rise are discussed in the present paper. The basic equation of motion is solved by a Galerkin method and the resulting time variable is solved by the hamonic balance method for periodic vibration

Advanced Materials Technologies, EarlyView.This paper presents an agar medium with a phosphorescent grid pattern that measures the stress distribution generated by growing plant roots. Using phosphorescence, the system optically separates the grid pattern from the root and extracts the grid deformation.

Strategies for increasing the operating frequency range of vibration energy harvesters: a review [PDF]
, 2010 This paper reviews possible strategies to increase the operational frequency range of vibration-based micro-generators. Most vibration-based micro-generators are spring-mass-damper systems which generate maximum power when the resonant frequency of the ...

Advanced Optical Materials, EarlyView.Mono‐ and bilayer MoS2 photodetectors enable wavelength‐selective AC photoresponse and optically driven capacitance modulation under visible illumination. Green excitation produces the strongest cumulative capacitive response, consistent with trap‐mediated charge accumulation at mono/bilayer and metal–MoS2 interfaces.
