“…More multistable mechanisms have been reported by using hybrid material systems. A quadri-stable compliant mechanism has been designed and tested by using a bistable curved beam embedded in an arch beam [46]. A bistable switching mechanism has been achieved through a hybrid system of curved strips attached to a center beam [58].…”

A paradigm shift has emerged over the last decade pointing to an exciting research area dealing with the harnessing of elastic structural instabilities for 'smart' purposes in a variety of venues. Among the different types of unstable responses, buckling is a phenomenon that has been known for centuries, and yet it is generally avoided through special design modifications. Increasing interest in the design of smart devices and mechanical systems has identified buckling and postbuckling response as a favorable behavior. The objective of this topical review is to showcase the recent advances in buckling-induced smart applications and to explain why buckling responses have certain advantages and are especially suitable for these particular applications. Interesting prototypes in terms of structural forms and material uses associated with these applications are summarized. Finally, this review identifies potential research avenues and emerging trends for using buckling and other elastic instabilities for future innovations.

This paper presents the design of a compliant mechanism that can be used as an amplifier mechanism of the micro linear actuator. The design includes the synthesis of pseudo rigid-body mechanism, the converting rigid mechanism to a compliant mechanism, the parameterization of dimensions of compliant mechanism, design variables' choice and the optimal design using ANSYS optimization tool. In addition, the paper also describes the use of response surface analysis tool of ANSYS Workbench to evaluate the effect of design variables on the optimization so that to investigate the sensitivity of those design variables on the objective function. The finite element model of the designed mechanism is established and used to simulate the compliant mechanism and to evaluate the amplification ability. The results show that the amplification ratio is higher than 10.

“…This widespread mechanism has been employed to design actuators with several stable positions. Among these mechanisms, we find tristable [27][28][29][30][31], quadristable [32,33] and pentastable designs. In the other hand, few unlimited multistable mechanisms are presented in the literature.…”

This paper presents a compliant monolithic multistable actuator which is able to switch its moving part between several stable positions linearly in one dimensional direction. The number of stable positions can be increased by extending the range of displacement of the moving part. The transition in each step of displacement is made to the nearest stable position in the direction of motion. Upward and downward steps are made by a specific sequence of moving, using a bistable module, opening and closing two internal clamps which are actuated by U-shaped electrothermal actuator using three subsystems. The principle and the design of each subsystem in the discrete acruator, fabrication process and experimental results are presented. The fabricated prototypes of the discrete actuator showed a proper functioning. The mean achieved displacement is 120.67±0.08 µm over 12 upward steps with a mean step of 10.06 µm, which is very close to the designed performance.
