In this work, we assess the potential of transition metal dichalcogenide (TMDC) semitransparent solar cells as emerging technology for this application. We model a semitransparent ultrathin photovoltaic device containing a MoS<sub>2</sub> or WSe<sub>2</sub> absorber and find that it can be optimized to produce a balanced absorption of the sunlight spectrum because of the unique optical properties of these materials, eliminating the common problem of the undesired coloring of the transmitted light. The device also exhibits high angular absorptance. We estimate a potential saving between 16% (winter) and 23% (summer) in the electricity consumption of a high-rise office building located in Madrid, Spain, by implementing TMDCs semitransparent windows with an average photopic transmission (APT) of 24%. Notably, this is compatible with a high quality in the transmitted light: the color rendering index (CRI) of the PV windows exceeds 90 for an APT between 23% and 65%. These results, along with the fact that TMDCs can be deposited using low-cost, scalable methods, indicate that TMDCs hold great potential for developing color-neutral, power-generating building glazing.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"25 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142671026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is an extreme challenge for artificial synapses to achieve self-optimized feedback of mimicking biological behavior. Herein, a novel self-powered artificial neural pathway (SANP) is developed by coupling CsPbBr<sub>x</sub>I<sub>(3-x)</sub>-based artificial synaptic device and triboelectric nanogenerator (TENG) for self-optimized neuromorphic computing. The TENG can convert external mechanical stimulation into electricity that acts not only as a supply source to power the SANP but also as electrical stimulation to transmit to the synaptic device for neuromorphic computing. The synaptic device’s conductance can be well modulated by the electrical stimulation, which tunes the height of Schottky barrier between Ag and CsPbBr<sub>x</sub>I<sub>(3-x)</sub>, to simulate the regulation of synaptic plasticity. Simultaneously, the synaptic device can implement synaptic functions of learning and memory. Furthermore, the SANP as self-powered mechano-nociceptor can successfully mimic the nociceptor features of “threshold”, “relaxation” and “allodynia”. More importantly, under repeated mechanical stimulation, the SANP with synaptic self-optimized feedback features enables the learning and memory training and the robotic arm’s grabbing and spreading simultaneously. Consequently, the SANP can effectively accomplish signal transmission, processing, and learning tasks without external power supply, which demonstrates potential application in neuromorphic computing and intelligent robots.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"113 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142671116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vibration detection at critical locations such as electrical motors and bearings within large equipment has emerged as an indispensable method for machinery health monitoring. Current vibration detection instruments mostly need to be powered by cables or batteries, which has application limitations in complex moving equipment and restricted space. In this paper, a disc-like triboelectric nanogenerator (DL-TENG) with a multi-sized honeycomb structure is proposed as an innovative solution for achieving wide band and high precision acceleration detection of the vibration. Multi-diameter polytetrafluoroethylene (PTFE) balls are used as friction materials to achieve the high voltage output of the TENG, providing sufficient energy for the detection circuit. By carefully designing suitable honeycomb structures for PTFE balls of different diameters, the ability to detect broadband vibration signals is obtained. The experimental results demonstrate that DL-TENG with honeycomb structure and multi-size PTFE balls can detect acceleration signals ranging from 10 to 2000 Hz, and the acceleration measurement range can reach 1-11<!-- --> <!-- -->m/s<sup>2</sup> with an acceleration resolution of 0.1<!-- --> <!-- -->m/s<sup>2</sup>. Moreover, DL-TENG can output more than 80<!-- --> <!-- -->V peak-to-peak under vibration conditions of 11<!-- --> <!-- -->m/s<sup>2</sup>. And under vibration conditions of 8<!-- --> <!-- -->m/s<sup>2</sup>, the DL-TENG can fully charge a 100 μF capacitor to 5<!-- --> <!-- -->V in just 100<!-- --> <!-- -->seconds. By equipping a special circuit for DL-TENG, wireless self-powered vibration detection is realized. This study is expected to be applied in the scenario of vibration information collection in complex ring vibration environment and provides a new paradigm for the realization of self-powered vibration sensors.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"64 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a highly strain-insensitive stretchable triboelectric tactile sensor (SS-TTS) is developed <em>via</em> an interfacial stress dispersion strategy.

Furthermore, the SS-TTS is seamlessly incorporated into a wearable wristband for precise monitoring of pulse signals regardless of human wrist size. This demonstrates its potential for personalized health monitoring applications. Additionally, a 3×3 triboelectric sensor array is constructed to function as a strain-insensitive stretchable touch panel for tactile imaging and trajectory recognition, further expanding the sensor's versatility.
