“…Bistable buckled beams, which undergo pre-buckling deformation under horizontal force, are among the most common bistable structures. The bistable characteristics of bistable buckled beams are influenced by a geometrical parameter Q = H/t, where H and t represent the arch height and thickness of the beams, respectively, as shown in figure 2(A) [20][21][22]. As the parameter Q increases, the beam transitions from the simple stability to monostability with snap-through instabilities, and ultimately to bistability.…”

Bistable structures have attracted attention due to their unique properties and potential applications in soft robotics, logic gates and energy harvesting devices. The bi-stability is always an inherent property if the bistable structures are pre-designed. A reprogrammable bistable structure that does not require re-designing and re-fabricating the prototype is highly desirable. Despite its vast potential and burgeoning interest, the field of reprogrammable bistable structures lacks a cohesive and comprehensive review. Therefore, this paper presents a state-of-the-art review of recent advances in the basic structural forms, key parameters determining bistable characteristics, active regulation mechanisms, and potential applications of reprogrammable bistable structures. It also presents the remaining challenges and suggests possible future research directions in the field of reprogrammable bistable structures. This review will provide valuable insights for researchers and engineers to explore the vast potential of reprogrammable bistable structures.

“…The effectiveness of bistable systems, a subset of non-linear systems, in harvesting energy across a broad frequency range from the ambient environment has been well-documented [13], with various methods employed to enable them [13][14]. The distinctive sensitivity of bistable systems to a broad spectrum of excitation frequencies has led to many investigations into the dynamic behavior of the bistable system [15][16][17][18][19][20][21][22]. Moreover, there have been few trials to numerically simulate the static behavior of such systems [16].…”

Monitoring of aquatic life is important for assessing long-term impacts on activities associated with fish stock and migration. One promising approach for long-term monitoring involves the development of self-powered telemetry devices capable of powering themselves by harnessing energy from the fish body undulations using implanted devices or from fluid motions generated by fish swimming using external devices. One of the latter devices is a broadband low frequency nonlinear bistable energy harvester. This cost-effective harvester has been inspired from the doubly curved leaf blades of a Venus-fly trap. This work examines the static behavior of such a bio-inspired bistable energy harvester by analyzing its force-displacement characteristics. The objective is to identify crucial design parameters to optimize the harvester's performance for potential application in self-powered fish telemetry tags. The unique characteristics of hysteresis loop and snap-through discontinuity of the harvester are investigated using finite element analysis. The finite element model is found to qualitatively replicate experimental observations. Additionally, geometrical and assembly parameters that affect the force-displacement behavior of the harvester are identified. A sensitivity analysis is performed to determine the effect of the aspect ratio, buckling displacement and thickness of the proposed harvester on the static force-displacement curve.

“…Currently, research on the structural design of NSMs is mainly based on the foundation of using beam buckling modes to generate NS effects [11][12][13]. In 2001, Lakes [14] provided a detailed definition of NS, which has characteristics opposite to those of normal objects in terms of force and deformation direction.…”

In this study, a new negative stiffness metamaterial (NSM) is designed using laminates with independent negative stiffness (NS) properties as the functional component and a discrete assembly method. In this paper, the metamaterial is designed by mathematical model, which have been verified and analyzed systematically by experiment and finite element (FE) method. The influence of each laminate parameter on the design of metamaterials under uniform distribution and gradient distribution was investigated, and based on this, the load-bearing capacity enhancement strategy of metamaterials was further explored. The metamaterial has the advantages of discrete assembly and designability, which solves the defects of the previous performance constrained by the structure and enhances the usability.
