Triboelectric nanogenerators (TENGs), distinguished by their self-powered capabilities, present a unique approach to tactile sensing due to their adeptness in converting mechanical stimuli into electrical energy. This paper provides a comprehensive review of recent advancements in TENG-based tactile sensors for robots' hands, highlighting their unique ability to convert mechanical stimuli into electrical energy, making them self-powered. This review is structured around two primary research approaches: basic and applied. Firstly, the basic research domain focuses on the case of extrusion or tensile deformation caused by touch or gripping motion based on TENG, designed for use in force and pressure sensors. The emphasis is on their substantial contribution to enhancing robot intelligence through continuous motion and capturing tactile data. Moving to applied research, the paper delves into various applications of TENG-based tactile sensors in robot hands, encompassing intelligent grasping and sensing, object recognition, texture recognition, multimodal sensing, and Human Machine Interaction (HMI). Finally, the paper outlines opportunities and challenges, providing valuable insights for future advancements in theoretical and applied research.</p></div>","PeriodicalId":18253,"journal":{"name":"Materials Today Physics","volume":null,"pages":null},"PeriodicalIF":10.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141542504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These materials not only exhibit outstanding absorption properties but also enhance our understanding of mechanisms associated with ion-based absorbers. The selective interaction of the ZIF-L framework results in distinct dielectric properties among imidazolium ILs with varying ion sizes and polarities. Analysis of relaxation behavior and ionic conductivity reveals that smaller ions facilitate better ionic transport and longer relaxation times by accessing the interior cavities, whereas larger ions experience extended charge transport distances within the framework gaps but shorter relaxation times due to the formation of short-range ordered structures. Moreover, these clay-like ionic conductors demonstrate excellent microwave absorption capabilities, with effective bandwidths of 2.3 GHz, 7.0 GHz, 6.7 GHz, and 7.4 GHz, respectively.

Despite the development of strain-sensitive materials and patterning technologies for improved performance and device integration, the metal film serving as interconnects is always vulnerable upon stretch, which hinders the operation under large strains. Herein, a novel strategy is developed for achieving stretch-tolerant interconnects within a sensor array. Through introducing a high-modulus capping layer for the deposition of Ag interconnects, followed by silanization-assisted lamination onto the stretchable substrate where strain-sensitive graphene patches are inkjet-printed, the deformation of Ag interconnects is largely suppressed upon the global strain of the device, and a high working range of 40 % strain is achieved. Moreover, the chemical bonding between the capping layer and the stretchable substrate ensures a stable contact between the electrode and the sensitive layer under vigorous bending. The as-prepared sensor array demonstrates high sensitivity (gauge factor (GF) &gt; 100) within a wide range (18 %), and could reliably monitor various physiological signals and human activities. A machine learning-assisted wearable gesture recognition system is developed based on the sensor array and a convolutional neural network (CNN), which could distinguish from 10 defined gestures with 100 % accuracy after 14 training processes. The facile and effective strategy could be universally applied for metal interconnects protection under stretch, and dramatically facilitate the design of smart flexible electronics.</p></div>","PeriodicalId":18253,"journal":{"name":"Materials Today Physics","volume":null,"pages":null},"PeriodicalIF":10.0,"publicationDate":"2024-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141482048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For out-of-plane structured WTEC using inorganic TE materials encapsuled in flexibility substrate, on the one hand, encapsulating materials are required to have low thermal conductivity, high reliability and high flexibility, and on the other hand, heat dissipation of devices is required to be lightweight, portable and efficient. For this reason, we propose a composite material synthesised from SiO<sub>2</sub> aerogel, hollow glass beads (HGB) and polydimethylsiloxane (PDMS) as a filler, which takes advantage of the low thermal conductivity of (0.094 W/mK) to increase the temperature difference in the encapsulation layer of the device, and moreover performs the fabrication of honeycomb holes, which further reduces the thermal conductivity of the encapsulation layer and at the same time brings a certain degree of compression resistance to the device. Radiative cooling (RC) films synthesised using hexagonal boron nitride (HBN) and PDMS for lowering the temperature of the hot side in outdoor environments without additional energy consumption, providing heat dissipation at the hot side. Honeycomb wearable thermoelectric cooler (HWTEC) proposed in this work deliver high cooling temperature difference of 9.1 °C and 6.5 °C indoor and outdoor through human wear.

The results suggest that enhanced exciton diffusion length and efficient exciton dissociation and charge generation are elemental characters to realize high PCE planar heterojunction organic solar cells.
