This paper provides a review of models and solutions for the buckling and postbuckling of
beams available from the 50s of the last century to date. Beams with axially unrestrained …

Aiming to achieve the high-performance piezoelectric energy harvester under broadband
vibrations, an outer-inner magnetic two-degree-of-freedom piezoelectric energy harvester is …

In this paper, a novel multiple-stable piezoelectric energy harvester with programmable
equilibrium point configurations is proposed. Currently, multi-stable energy harvesters have …

Piezoelectric energy harvesters (PEHs) have attracted great attention to solve the power
supply issue of wireless sensors in rotational motions. PEHs based on smart structures and …

This paper reports, for the first time, experimental evidence of the effectiveness of the
frequency-tuning synchronized electrical charge extraction technique (FTSECE) with a …

Vibrational energy harvesters, and more particularly piezoelectric devices, usually feature
two limitations: their narrow frequency band and their relatively limited conversion abilities …

At present, for the widely used Duffing-type bi-stable energy harvesters (D-BEH) with smooth
nonlinear forces, there is a trade-off between large equilibrium point coordinates and small …

The paper studies the electrical response of an array of piezoelectric oscillators attached to
the synchronized electric charge extraction (SECE) interface circuit. The analytic estimate of …

As one of the basic motion forms, rotational motion exists widely in nature and artificial
mechanical structures, such as joint rotation, gear transmission and bearing rolling. Energy …

In this study, a novel quad-stable energy harvester (QEH) is developed, in which its
coordinates of equilibrium points can be user-defined like programming. This programmable …
