“…Ueda [25]- [27] introduced the two-port concept in the Castigliano's modeling process to simplify the modeling procedures, which is well-suited for the nested multistage amplifier. Wu et al [28] integrated the screw theory with the energy method to formulate a general kinetostatic model of compliant mechanisms, which regulates the form of the derived formulas and brings conciseness. Even though, Castigliano's second method is not a mainstream approach of FDAMs' modeling due to its inherent drawback.…”

Multifarious flexure-based displacement amplifiers have been proposed and studied in the past decades, showing importance in many industrial fields, such as bioengineering, optical instruments, and semiconductor technology. Displacement amplifiers provide precise motion and large stroke through a simple and low-cost way compared with other piezoelectric actuators. Those merits have opened a door for new and advanced micro devices with unprecedented performance. This paper aims to proffer a comprehensive review on the design, modeling, characteristics, and applications of flexure-based displacement amplifiers, following by pointing out the inherent drawbacks in this research area such as amplification ratio limit, parasitic motion, low lateral stiffness, low natural frequency, and discussing existing solutions and some potential research directions in those topics. Finally, a summary is concluded and the future development perspectives of the displacement amplifiers are discussed. This review contributes to giving a comprehensive understanding of the displacement amplifier, which provides guidance on designing new displacement amplifiers for improving their mechanical output performance. It is also expected to be instrumental for related researchers to understand displacement amplifiers, and to successfully select and design for specific applications.

“…Although an extensive amount of research has already been done in the area of compliance or stiffness analysis [3,4,[14][15][16][17], most of these study deal with the case of planar mechanisms or in applications involving planar motions. There is not much work available for spatial mechanisms having multiple degree-of-freedom (DOF).…”

With many micromanipulator designs emerging in micro and nanosystem applications, the element of compliance in the mechanisms is gaining attention. Several designs consider motions limited in a plane for high accuracy and repeatability as needed in micro/nano manipulation applications. Extending this to a full spatial configuration with coupled motions of series and parallel linkages with flexure joints of 1-degree-of-freedom (DOF) and 3-DOF needs a systematic analytical approach. One such approach for compliance analysis is presented in this article for a mechanism designed at Indian Institute of Technology Kharagpur. To validate the analytical models, finite element analysis simulations are performed with the help of the Abaqus-6.14 software package. Following the successful validation, the effect of structural parameters on the performance is presented with the help of the analytical expressions. We explore the performance of the mechanism with different dimensions of flexures of a particular type. Results indicate that the design with dissimilar dimensional parameters can give superior performance.

“…Beam mechanism and beam theory have been widely used in many engineering fields such as compliant mechanisms [1][2][3][4][5][6][7], flexible hinges [8][9][10][11][12][13][14][15], soft robots [16][17][18][19][20][21], piezoelectric beam-based energy harvesters [22][23][24][25], and leaf springs [26][27]. Compliant mechanisms exploit the deflection of the beams to transfer or transform the smooth and precise force and motion.…”
