“…The current miniaturized solutions for sensor networks require ad hoc solutions that are, in most cases, not yet industrialized [ 122 , 123 ]. The harvesting technique employed in geohazard monitoring can surely benefit from miniaturized solar cells [ 124 ] to reduce the nodes’ dimensions. The employment of machine learning and artificial intelligence has various application possibilities in geohazard monitoring and is currently a very studied field [ 125 ].…”

Rockfalls and landslide events are caused by different factors among which are included geomorphological and climatic factors and also human interaction. Therefore, the economic and social impacts can be significant and the remote monitoring of such hazards has become an essential topic in various applications. Wireless sensor networks (WSNs) are well suited for the deployment of monitoring systems, benefiting from the different technologies and topologies that are available and evolving nowadays. This review paper aims to summarize and overview the up-to-date state of the art of rockfall and landslide monitoring systems based on WSNs. The implementation and methods were analyzed for each solution, along with the system architecture and relevant hardware aspects. All the retrieved data were used to analyze the current trends and future possibilities in the field of WSN geohazard monitoring.

“…made a three-electrode BPV with Chlorella vulgaris and Rhodopseudomonas palustris as biological materials, and found that the potential required to extract electrons from the latter was lower, and had lower dependence on external electron mediator. Besides biological combination, BPV can also be combined with other electrical devices to improve current output efficiency, such as self-charging supercapacitors ( Das et al., 2018 ; Liu and Choi, 2020a ; Liu and Choi, 2020b ; Powell et al., 2021 ; Alajmi et al., 2022 ; Pankratova et al., 2022 ) or more complex boost converters ( Hill and Bendall, 1960 ; Singh and Pandit, 2013 ; Oseyemi et al., 2022 ).…”

As the most suitable potential clean energy power generation technology, biophotovoltaics (BPV) not only inherits the advantages of traditional photovoltaics, such as safety, reliability and no noise, but also solves the disadvantages of high pollution and high energy consumption in the manufacturing process, providing new functions of self-repair and natural degradation. The basic idea of BPV is to collect light energy and generate electric energy by using photosynthetic autotrophs or their parts, and the core is how these biological materials can quickly and low-loss transfer electrons to the anode through mediators after absorbing light energy and generating electrons. In this mini-review, we summarized the biological materials widely used in BPV at present, mainly cyanobacteria, green algae, biological combinations (using multiple microorganisms in the same BPV system) and isolated products (purified thylakoids, chloroplasts, photosystem I, photosystem II), introduced how researchers overcome the shortcomings of low photocurrent output of BPV, pointed out the limitations that affected the development of BPV’ biological materials, and put forward reasonable assumptions accordingly.

In this study, textile‐based microbial photoelectrochemical solar cells are developed for flexible electronic device applications. Configuration of the self‐pumping microfluidic channel without a proton exchange membrane is adopted to miniaturize the biophotovoltaic device. The microchannel region of the miniature device is patterned by silk screen printing using a body‐friendly Ecoflex to maintain the flexibility of the fabric substrate. Gold nanoparticle biosynthesized Synechocystis sp. PCC 6803 biocatalyst, supercapacitive ternary nanocomposite anode, and solid‐state Ag2O oxidant are used to enhance the biosolar cell performance. A maximum current density of 135.1 µA cm−2 and peak power density of 14.1 µW cm−2, which are higher than previous textile‐based microbial fuel cells, are achieved in the presence of light. The monolayer fabric‐based biosolar cell has a stable performance up to 100 and 20 cycles of stretching and twisting, respectively. The presented new platform of flexible microbial solar cells offers the development possibility of self‐sustaining wearable electronics.
