“…Various energy-harvesting techniques such as piezoelectricity, triboelectricity, pyroelectricity, and electromagnetism open the way to replace external power sources with self-driven on-body power sources for wearable electronics. Among them, a triboelectric nanogenerator (TENG) owing to its numerous advantageous features like simple fabrication process, lightweight characteristic, high output, cost-effectiveness, and preferably, durability shows application prospects to convert the low-frequency body motions to electrical energy on the account of triboelectrification and electrostatic induction. − Different conducting polymers such as polyaniline and polypyrrole have been used in the formulation of TENG-based gas sensors, where the same polymer layer serves as a power source and sensing material . Nevertheless, these conducting polymers show a good triboelectrification effect, flexibility, and portability; however, they are restricted on the basis of low sensitivity performance.…”

Real-time monitoring of harmful gases is of great significance to identify the environmental hazards to people's lives. However, this application scenario requiring low-power consumption, superior sensitivity, portability, and self-driven operation of gas sensors remains a challenge. Herein, an electrospun triboelectric nanogenerator (TENG) is synthesized using highly electronegative and conducting MXene nanofibers (NFs) paired with biodegradable cellulose acetate NFs (CA-NFs) as triboelectric layers, which supports a sufficient power density (∼1361 mW/m 2 @2 MΩ) and shows a self-powered ability to operate the chemiresistive gas sensor fabricated in this work. Further, by using cellulose nanofibers (C-NFs) as a substrate, a new kind of MXene/TiO 2 /C-NFs heterojunction-based sensory component is developed for detection of NH 3 . This sensor exhibits excellent reproducibility, high selectivity, and sensitivity toward NH 3 (1−100 ppm) along with a fast response/recovery time (76 s/62 s) at room temperature. Finally, a monitoring system comprising a TENG-powered sensor, an equivalent circuit, and an LED visualizer has been assembled and successfully demonstrated as a fully self-powered device for NH 3 leakage detection. Thus, this work pushes forward the intelligent gas sensing network self-driven by human motion energy, dispensing the external battery dependence for environment monitoring to reduce the possible health effects.

“…Air/wind flow can also be harnessed as an energy source for IoBNT. In [136], a rotating TENG based on GO-filled polyvinylidene fluoride films was developed to harvest energy from airflow. In contrast to studies where GRMs constitute the harvester or part of it, some research focuses on using graphene to enhance the performance of existing harvesters.…”

The Internet of Everything (IoE) is a recently introduced information and communication technology (ICT) framework promising for extending the human connectivity to the entire universe, which itself can be regarded as a natural IoE, an interconnected network of everything we perceive. The countless number of opportunities that can be enabled by IoE through a blend of heterogeneous ICT technologies across different scales and environments and a seamless interface with the natural IoE impose several fundamental challenges, such as interoperability, ubiquitous connectivity, energy efficiency, and miniaturization. The key to address these challenges is to advance our communication technology to match the multi-scale, multi-modal, and dynamic features of the natural IoE. To this end, we introduce a new communication device concept, namely the universal IoE transceiver, that encompasses transceiver architectures that are characterized by multi-modality in communication (with modalities such as molecular, RF/THz, optical and acoustic) and in energy harvesting (with modalities such as mechanical, solar, biochemical), modularity, tunability, and scalability. Focusing on these fundamental traits, we provide an overview of the opportunities that can be opened up by micro/nanoscale universal transceiver architectures towards realizing the IoE applications. We also discuss the most pressing challenges in implementing such transceivers and briefly review the open research directions. Our discussion is particularly focused on the opportunities and challenges pertaining to the IoE physical layer, which can enable the efficient and effective design of higher-level techniques. We believe that such universal transceivers can pave the way for seamless connection and communication with the universe at a deeper level and pioneer the construction of the forthcoming IoE landscape.Index Terms– Internet of Everything, Universal IoE Transceiver, Interoperability, Multi-modality, Hybrid Energy Harvesting, Molecular Communications, THz Communications, Graphene and related nanomaterials.

Triboelectric nanogenerators (TENGs) with great potential in the field of energy collection and self‐powered sensing have attracted great attention. However, most of the TENGs are limited by their unsatisfactory electrical output performance and mechanical properties in utilized as wearable and flexible microelectronic devices. Herein, a flexible single‐electrode triboelectric nanogenerator composed of bismuthene (Bi‐ene) nanosheets embedded in a polydimethylsiloxane (PDMS) film is proposed. The Bi‐ene nanosheets embedded in the PDMS film act as micro‐capacitors, which enable the Bi‐ene@PDMS film to withstand high voltage and store more electrical energy. As a result, the Bi‐ene@PDMS based TENG exhibits 26 times more power density than that of the pure PDMS based TENG at the optimum Bi‐ene content. Moreover, the prepared TENG based e‐skin can meet the practical needs of power supply, motion sensing, and tactile sensing. The results can provide fundamental insights for the design of high‐performance flexible TENG.
