“…[83] Two common crystal structures for piezoelectric materials are the perovskite and wurtzite structures. [84] The perovskite crystal structure is a cubic crystal system, and its chemical formula is usually ABO 3 , so this structure is also called ABC-type ternary compound structure. In this system, A and C ions usually occupy body-centered and face-centered positions, respectively, while B ions usually occupy the body-centered position.…”

Neurological diseases are a major global health challenge, affecting hundreds of millions of people worldwide. Ultrasound therapy plays an irreplaceable role in the treatment of neurological diseases due to its non‐invasive, highly focused, and strong tissue penetration capabilities. However, the complexity of brain and nervous system and the safety risks associated with prolonged exposure to ultrasound therapy severely limit the applicability of ultrasound therapy. Ultrasound‐sensitive intelligent nanosystems (USINs) are a novel therapeutic strategy for neurological diseases that bring greater spatiotemporal controllability and improved safety to overcome these challenges. This review provides a detailed overview of therapeutic strategies and clinical advances of ultrasound in neurological diseases, focusing on the potential of USINs‐based ultrasound in the treatment of neurological diseases. Based on the physical and chemical effects induced by ultrasound, rational design of USINs is a prerequisite for improving the efficacy of ultrasound therapy. Recent developments of ultrasound‐sensitive nanocarriers and nanoagents are systemically reviewed. Finally, the challenges and developing prospects of USINs are discussed in depth, with a view to providing useful insights and guidance for efficient ultrasound treatment of neurological diseases.This article is protected by copyright.

“…Recent progress in piezoelectric materials and manufacturing methods at the micro and nanoscale have broadened the application fields of piezoelectric technology. Materials like ceramics [23,24], polymers [25,26], composites [27,28], and biocompatible materials [5,29], in diverse nanostructures [30,31] and thin films [32,33], exhibit satisfactory physical properties such as high piezoelectric coefficients, flexibility, stretchability, and durability. This study explores the principles of piezoelectricity and the choice of materials, emphasizing the role of piezoceramics and piezoelectric composites in SHM.…”

In the field of structural engineering, the integration of smart materials and structural health monitoring (SHM) has given rise to self-sensing materials (SSM), leading to a paradigm shift in SHM. This paper focuses on the interplay between self-sensing capabilities and the piezoelectric properties of lead zirconate titanate (PZT) and barium titanate (BT) in aluminium components. Leveraging Friction Stir Processing (FSP), the study explores the synthesis and performance of self-sensing materials with embedded piezoelectric particles, potentially transforming structural engineering. The paper highlights FSP as a key methodology for incorporating piezoelectric particles into structural materials, showcasing its potential in developing self-sensing materials with enhanced functionalities. A specific focus is placed on integrating PZT and BT particles into AA2017-T451 aluminium parts using FSP, with metallographic assessments and mechanical property evaluations conducted to analyse particle distribution and concentration. This study shows how BT and PZT particles are incorporated into AA2017-T451 aluminium to create a self-sensing material that responds to external stimuli. Under cyclic loading, the self-sensing materials exhibit a linear load-electrical response correlation, with sensibility increasing at lower frequencies. Metallographic analysis shows homogeneous particle distribution, while PZT induces increased brittleness and brittle fractures. Yield strength remains relatively stable, but ultimate strength decreases post-FSP. Hardness variations indicate weaker bonding with PZT particles. Eddy's current testing aligns with hardness profiles, and sensorial characterization reveals a non-linear frequency-sensibility relationship, showcasing the SSMs' suitability for low-frequency applications, particularly with PZT embedment.
