Thus, it can be a promising strategy to build self-powered sensors. Specifically, there are mainly two approaches to construct osmotic energy-based self-powered sensors. One is harvesting osmotic energy as power supplies for existing sensors. The other is directly establishing active self-powered sensors. Both of the two approaches have developed rapidly in recent years. In this review, recent publications about osmotic energy conversion systems for self-powered sensors are presented. Firstly, the related history and mechanism are systematically summarized. Then, the recent progress of relevant power supplies and active sensors in recent 8 years are successively introduced. Considering nanopore/nanochannel-based selective membrane as one of the key units of ion transport-based energy conversion systems, the introduction is made around different kinds of selective membranes, including symmetric membranes with single-channel/pore, porous structures built by plenty of nanochannels/nanopores, and Janus membranes with asymmetric pore structures. Finally, future challenges of osmotic energy conversion systems for self-powered sensors are listed and analyzed. We believe this review could provide valuable guidance for relevant researchers to promote osmotic energy conversion technology and self-powered sensors to a broader range of applications.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"132 ","pages":"Article 110412"},"PeriodicalIF":16.8,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142489288","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}

Herein, we investigated the coupling between tribovoltaic and tribo-electrostatic effects at the dynamic heterojunctions of two wide-bandgap semiconductors: zinc oxide (ZnO) and gallium nitride (GaN). It is found that, in the contact-separation mode, the direct-current outputs from tribovoltaic effect can be clearly distinguished from the alternating-current outputs from tribo-electrostatic effect. Then, humidity, external load resistance and pressure force are found to reveal the coupling characteristics of these two effects, that tribovoltaic outputs are less affected by humidity, show smaller matched impedance and are more sensitive to high pressure force, diverging from the tribo-electrostatic outputs. Lastly, we demonstrate that the mechanical wearing effect can be inhibited in contact-separation mode, achieving long-term stability over 50,000 cycles.

The film formation process after the solution coating or printing is complex and starts with solvent removal which triggers the crystallization of the perovskite phase. Before the crystallization onset, the solvent continual removal causes the wet film drying or chemical changes that lead to a supersaturated system or a stabilized intermediate structure which subsequently transforms into the targeted perovskite phase. As such, the kinetics of solvent removal and film drying greatly influences the morphology and microstructure of solution-processed perovskite films. Scalable solution deposition processes generally form thick wet films with high solvent contents, which need to be controlled to obtain desired properties. This review describes the formation of perovskite films from scalable processes, with a special focus on the interplay between solvent removal and film solidification. The understanding of chemical and physical processes taking place as the forming film undergoes a range of transitions is discussed. In addition, the control strategies of solvent removal to rapidly induce supersaturation in scalable processes are reviewed along with the reasons behind irregularities formation in large-area films. Furthermore, different predictive models describing the kinetics of changes in dying films of perovskites are also examined.
