In this paper, the mechanical response of a one-dimensional (1D) hexagonal piezoelectric quasicrystal (PQC) thin film is analyzed under electric and temperature loads. Based on the Euler-Bernoulli beam theory, a theoretical model is proposed, resulting in coupled governing integral equations that account for interfacial normal and shear stresses. To numerically solve these integral equations, an expansion method using orthogonal Chebyshev polynomials is employed. The results provide insights into the interfacial stresses, axial force, as well as axial and vertical deformations of the PQC ***, fracture criteria, including stress intensity factors, mode angles, and the Jintegral, are evaluated. The solution is compared with the membrane theory, neglecting the normal stress and bending deformation. Finally, the effects of stiffness and aspect ratio on the PQC film are thoroughly discussed. This study serves as a valuable guide for controlling the mechanical response and conducting safety assessments of PQC film systems.

Integrated sensing and communication (ISAC) is a promising technique to increase spectral efficiency and support various emerging applications by sharing the spectrum and hardware between these functionalities. However, the traditional ISAC schemes are highly dependent on the accurate mathematical model and suffer from the challenges of high complexity and poor performance in practical scenarios. Recently, artificial intelligence (AI) has emerged as a viable technique to address these issues due to its powerful learning capabilities, satisfactory generalization capability, fast inference speed, and high adaptability for dynamic environments, facilitating a system design shift from model-driven to data-driven. Intelligent ISAC, which integrates AI into ISAC, has been a hot topic that has attracted many researchers to investigate. In this paper, we provide a comprehensive overview of intelligent ISAC, including its motivation, typical applications, recent trends, and challenges. In particular, we first introduce the basic principle of ISAC, followed by its key techniques. Then, an overview of AI and a comparison between model-based and AI-based methods for ISAC are provided. Furthermore, the typical applications of AI in ISAC and the recent trends for AI-enabled ISAC are reviewed. Finally, the future research issues and challenges of intelligent ISAC are discussed.
