“…Consequently, there has been extensive research regarding the development of actuators in the form of composites reinforced with piezoelectric fibers. 63 Dumoulin and Deraemaeker 62 explored the possibility of using composites with lead zirconate titanate (PZT) piezoelectric fibers as transducers (emitters and receivers) for monitoring concrete structures. The effective properties of piezoelectric composites were investigated using numerical and analytical models.…”

Smart textiles (ST) can be defined as materials capable of detecting an external stimulus, responding, and adapting its behavior according to the stimulus obtained. The field of study and development of these materials is extensive, and ST can be seen in areas such as health, transport, security, civil construction, and sports. Piezoelectric textiles are part of the ST category and are characterized due the ability to generate electrical energy from mechanical stimulus, and vice versa. Therefore, the main objective of this review is to present the current research on piezoelectric ST. In addition, the study highlights the process of obtaining materials with piezoelectric properties and the challenges and limitations, seeking to understand the contribution of the development of these materials in the field of wearable electronic devices. Thus, the main challenge in developing piezoelectric textiles is in the ability to supply energy to electronic devices to be applied in various fields such as motion detection, acoustics, impact absorption, among others. Moreover, piezoelectric ST is remarkably promising for the development of wearable electronic textiles (e-textiles) that consequently impact the creation of new functional materials that enable renewable sources to offer a positive contribution in the daily society.

Piezoelectric ceramics are a very popular material in the field of actuator technology due to their unique piezoelectric properties. However, the brittle behavior of ceramics endangers the reliability of piezoelectric actuators. In this article, the three-dimensional braided piezoelectric composite is utilized to ameliorate the reliability and driving capability of piezoelectric actuators. The static analysis of laminated beam with the distributed braided piezoelectric composite actuator is presented to study its driving capability. Based on the piezoelectric constitutive equations and Euler–Bernoulli beam theory, the governing equation of the piezoelectric laminated beam is derived. The least-squares method for the piezoelectric laminated beam is established to solve the derived governing equation. The current approach is validated by comparison with published results and finite element results. In the numerical examples, the effects of the number and spacing of the three-dimensional braided piezoelectric composite patches, actuator central location, actuator length, actuator thickness ratio, cantilever beam thickness, applied voltage and fiber volume fraction on the driving capability of the distributed braided piezoelectric composite actuator are investigated. This study suggests the potential use of the distributed braided piezoelectric composite actuator in intelligent structures and provides useful guidance for the design and optimization of piezoelectric actuators.

This paper investigates the electromechanical behavior of functionally graded piezoelectric composite beams containing axially functionally graded (AFG) beam and piezoelectric actuators subjected to electrical load. The mechanical properties of the AFG beam are assumed to be graded along the axial direction. Employing the electromechanical coupling theory and load simulation method, the expression for the simulation load of the piezoelectric actuators is obtained. Based on Euler-Bernoulli beam theory and the obtained simulation load, the differential governing equation of the piezoelectric composite beams subjected to electrical load is derived. The integration-by-parts approach is utilized to solve the differential governing equation, and the expression for the deflection of the piezoelectric composite beams is obtained. The accuracy of the proposed method is validated by the finite element method. The bending response of the functionally graded piezoelectric composite beams is investigated through the proposed method. In the numerical examples, the effects of electrical load, actuator thickness, AFG beam thickness and AFG beam length on the electromechanical behavior of the functionally graded piezoelectric composite beams are studied.
