“…Many semiconductor materials are widely used in piezoelectric tactile sensors, such as ZnO, 109–111 BaTiO 3 , 112–114 and Pb(Zr,Ti)O 3 , 115,116 and are known as piezoelectric semiconductor materials because of their piezoelectric effects. Piezoelectric semiconductors generally suffer from rigidity and brittleness, and cannot meet the design requirements of flexible tactile sensors.…”

Intelligent applications, with tactile sensors at their core, represent significant advancement in the field of artificial intelligence. However, achieving perception abilities in tactile sensors that match or exceed human skin remains a formidable challenge. Consequently, the design and implementation of hierarchical structural materials are considered the optimal solution to this challenge. In contrast to conventional methods, such as complicated lithography and three‐dimensional printing, the cost‐effective and scalable nature of advanced solution‐synthesis methods makes them ideal for preparing diverse tactile sensors with hierarchical structural materials. However, the process and applicability of advanced solution synthesis methods have yet to form a seamless system. Accordingly, the development and intellectualization of tactile sensors based on advanced solution synthesis methods are still in their early stages, and require a comprehensive and systematic review to usher in progress. This study delves into the advantages and disadvantages of various advanced solution synthesis methods, providing detailed insights. Furthermore, the positive effects of hierarchical structural materials constructed using these methods in tactile sensors and their intelligent applications are also discussed in depth. Finally, the challenges and future opportunities faced by this emerging field are summarized.image

Cermet has broad applications in electronics, but achieving stable ceramic‐metal contact has always been a challenge, particularly at hot temperature and large deformation conditions, due to the significant differences in thermal expansion coefficient and stiffness of ceramics and metals. Here, stress matching and strong interphase bonding at the heterogenous ceramic‐metal contact are realized by using flexible ceramics, leading to stable applications in flexible fire‐resistant pressure tactile sensors. Cu/Au nanolayers are deposited first onto the toughened flexible SiO2 nanofibers with a chemical plating method to form sensitive interdigital electrode sensors, then use an in situ thermal reaction strategy to form conformal and interlocked Au3Cu and CuSiO3 interphases, which enhance the mechanical thermal stability of the ceramic‐metal contact. With deep learning technique, the as‐fabricated intelligent pressure tactile gloves can accurately recognize the human body parts in low‐visible burning environments and show a long‐term stability over 1000 cycles with a high sensitivity of 112.18 kPa−1, which is important for developing intelligent firefighting.

Over the past few decades, significant progress in piezo‐/tribo‐electric nanogenerators (PTEGs) has led to the development of cutting‐edge wearable technologies. Nanofibers with good designability, controllable morphologies, large specific areas, and unique physicochemical properties provide a promising platform for PTEGs for various advanced applications. However, the further development of nanofiber‐based PTEGs is limited by technical difficulties, ranging from materials design to device integration. Herein, we systematically review the current developments in PTEGs based on electrospun nanofibers. The review begins with the mechanisms of PTEGs and the advantages of nanofibers and nanodevices, including high breathability, waterproofness, scalability, and thermal–moisture comfort. In terms of materials and structural design, novel electroactive nanofibers and structure assemblies based on one‐dimensional micro/nanostructures, two‐dimensional bionic structures, and three‐dimensional multilayered structures are discussed. Subsequently, nanofibrous PTEGs in applications such as energy harvesters, personalized medicine, personal protective equipment, and human‐machine interactions are summarized. Nanofiber‐based PTEGs still face many challenges such as energy efficiency, material durability, device stability, and device integration. In the final section of this review, the research gap between research and practical applications of PTEGs is discussed, and emerging trends are proposed, providing some ideas for the development of intelligent wearables.This article is protected by copyright.
