“…Recently, ultrasound has been revisited as a promising way to deliver power safely into implanted medical devices. TENGs proved to play a crucial role in converting externally applied ultrasound into internal electricity inside the body, eliminating the need for replacement batteries that entail additional surgery (Figure c). − Sound is another green energy source for harvesting that exists everywhere. Various concepts of TENGs for sound energy harvesting have been reported, including an acoustic core–shell resonance harvester for the application of artificial cochleae based on the piezo-triboelectric effect (Figure d), a dual-tube Helmholtz resonator-based TENG, an integrated TENG with an electrospun polymer tube, and a 3D-printed acoustic TENG for a self-powered edge sensing system .…”

Serious climate changes and energy-related environmental problems are currently critical issues in the world. In order to reduce carbon emissions and save our environment, renewable energy harvesting technologies will serve as a key solution in the near future. Among them, triboelectric nanogenerators (TENGs), which is one of the most promising mechanical energy harvesters by means of contact electrification phenomenon, are explosively developing due to abundant wasting mechanical energy sources and a number of superior advantages in a wide availability and selection of materials, relatively simple device configurations, and low-cost processing. Significant experimental and theoretical efforts have been achieved toward understanding fundamental behaviors and a wide range of demonstrations since its report in 2012. As a result, considerable technological advancement has been exhibited and it advances the timeline of achievement in the proposed roadmap. Now, the technology has reached the stage of prototype development with verification of performance beyond the lab scale environment toward its commercialization. In this review, distinguished authors in the world worked together to summarize the state of the art in theory, materials, devices, systems, circuits, and applications in TENG fields. The great research achievements of researchers in this field around the world over the past decade are expected to play a major role in coming to fruition of unexpectedly accelerated technological advances over the next decade.

Since the beginning of human history, the demand for effective healthcare systems for diagnosis and treatment of health problems has grown steadily. However, traditional centralized healthcare requires hospital visits, making in‐time and long‐term healthcare challenging. Bioelectronics has shown potential in patient‐friendly healthcare owing to the rapid advances in diverse fields of biology and electronics. In particular, wearable and implantable bioelectronics have emerged as an alternative or adjunct to conventional healthcare. To develop into next‐generation healthcare systems, however, custom designs for biological targets with a deepened understanding of the intrinsic features of the target are essential. In addition, bioelectronic systems must be designed eco‐friendly for sustainable healthcare. In this review, bioelectronics as eco‐friendly and patient‐friendly integrated nanoarchitectonics as next‐generation smart healthcare technology are described. For an in‐depth understanding of biological targets and guidelines for target‐tailored design, we discuss target‐specific considerations and relevant key parameters of bioelectronic systems with the representative examples.

“…High photoluminescence quantum yield (PL QY), high photostability, and excellent biocompatibility are the key indicators of fluorescent materials. High-performance fluorescent materials are urgently demanded in light-emitting devices (LEDs), bioimaging, and biosensors. − To date, various high-performance fluorescent nanomaterials, including semiconductor quantum dots (QDs), and metal photoluminescent nanomaterials have been designed to satisfy the practical requirements of sensing, imaging, solar, and optoelectronic devices due to their novel physicochemical properties. − Since semiconductor QDs possess several advantages, including the ease of preparation, size-dependent emission wavelength, high-quantum yield, and photostability, their toxic precursors and the potential leaching of toxic metal ions have raised safety and environmental issues. − Otherwise, the metal photoluminescent nanomaterials including the metal-based nanoparticles and clusters have been demonstrated as novel fluorescent nanomaterials due to their tunable fluorescence wavelength and high color purity. Nevertheless, the expensive precursors, lower PL QY, and complex synthetic technology seriously restrict their practical applications. − With the ever-accelerated updating of science and technology, the new class of fluorescent carbon-based nanomaterials, such as fluorescent graphene, semiconductor polymer nanoparticles, and carbon nanodots (CNDs), − have developed with high PL QY, excellent color purity, or photobleaching resistance, thus endowing their more optional application fields as fluorescent materials.…”

Safely recycling high-performance fluorescent materials from waste is an appealing route to reduce environmental pollution. This work presents one facile approach to massively producing high-performance carbon nanodots (CNDs) from discarded cooked eggshells. The obtained CND solution exhibits two excitation-independent deep-red emission peaks at 632 and 700 nm with a high photoluminescence quantum yield of 19.98% and a narrow full width at half-maximum (FWHM) of 16.2 nm. The deep-red emission of the CNDs originates from the porphyrin-like structure in the CNDs, which are formed in the eggshells and further carbonized by cooking. In addition, the deepred emission and unprecedented narrow FWHM of the CNDs deliver promising applications in bioimaging as an imaging agent. The recycled deep-red emissive CNDs pave a new strategy to design nanomaterials from biomass and provide a novel green pathway to recycle high-performance fluorescent nanomaterials sustainably.
