Two-dimensional (2D) semi-conductive transition metal dichalcogenides (TMDCs) have shown advantages for logic application. Complementary metal-oxide-semiconductor (CMOS) inverter is an important component in integrated circuits in view of low power consumption. So far, the performance of the reported TMDCs-based CMOS inverters is not satisfactory. Besides, most of the inverters were made of mechanically exfoliated materials, which hinders their reproducible production and large-scale integration in practical application. In this study, we demonstrate a practical approach to fabricate CMOS inverter arrays using large-area p -MoTe 2 and n -MoS 2 , which are grown via chemical vapor deposition method. The current characteristics of the channel materials are balanced by atomic layer depositing Al 2 O 3 . Complete logic swing and clear dynamic switching behavior are observed in the inverters. Especially, ultra-low power consumption of ∼0.37 nW is achieved. Our work paves the way for the application of 2D TMDCs materials in large-scale low-power-consumption logic circuits.

Organic–inorganic halide perovskite materials exhibit excellent memristive properties, such as high ON/OFF ratio and low switching voltage. However, the toxicity of lead and poor stability strictly limit their further commercial applications. Herein, a high-quality nontoxic and stable AgBiI4 perovskite film is successfully synthesized via a low-temperature dynamic hot casting method, and resistive switching (RS) memory devices based on AgBiI4 are reported for the first time. The RS memory devices with the ITO substrate exhibit typical bipolar nonvolatile memory behaviors with an ultralow operating voltage (≈0.16 V), high ON/OFF ratio (≈104), reversible RS by pulse voltage operation (>700) and long data retention (>104 s), superior to those of most of the other perovskite-based memory devices. Furthermore, a high performance flexible nonvolatile resistive switching (RS) memory device based on a AgBiI4 perovskite with a PEN substrate is fabricated. The flexible device also displays good stability under repeated bending tests (>1000 cycles). By analyzing the current–voltage responses, and the transmission electron microscopy, energy dispersive spectroscopy and X-ray photoelectron spectroscopy results, we propose a mechanism involving conducting filaments formed by Ag cations to describe the RS behavior of the Ag/PMMA/AgBiI4/ITO device. Our work demonstrates that AgBiI4 is promising for nonvolatile memory devices and paves the way for realizing low-power consumption flexible nonvolatile memory devices.

The detection of low-concentration hydrogen at room temperature is still a challenge, which contributes to taking precautions as soon as possible when hydrogen leaks. In this study, we prepared Pt/SnO 2 -Pd nanomaterial as nanoelectrode applied for a fuel cell-type hydrogen sensor with zero power consumption . The sensing results show that such fuel cell-type H 2 gas sensor has high selectivity and good sensitivity to H 2 gas, with an unprecedented low detection limit of 1 ppm, and the humidity has little impact on the sensor's performance. Based on DFT calculations, the low adsorption energy and the electron transfer interaction between Pd and H promote the adsorption and dissociation processes of H 2 molecules, which lead to the hydrogen oxidation reaction acceleration and shorter times of response and recovery. In addition, this Pt/SnO 2 -Pd based sensor has also advantages of high selectivity and zero-power consumption, which may provide a broad application prospect for fuel cell vehicles and voltage transformers, etc.

Conventional metal oxide semiconductor gas sensors are inherently limited by their dependence on high operating temperatures (200–400℃), which leads to increased energy consumption and reduced long-term device stability. To overcome these challenges, this study presents a glycine-assisted solvent evaporation synthesis route for the preparation of highly dispersible WO 3 nanoparticles. Glycine acts dually as a crystallographic modulator during nanoparticle growth and as an interfacial stabilizer, allowing for control over both particle size and oxygen vacancy concentration. Subsequent annealing removes residual glycine while preserving the optimized nanostructure. The optimized 6-WO 3 sensor synthesized using 6 mmol glycine exhibits remarkable low-temperature sensing performance, demonstrating a response value of 270.9 toward 3 ppm NO 2 at a reduced operating temperature of 120°C compared to conventional WO 3 -based counterparts while maintaining high sensitivity. Systematic characterization links this energy-efficient performance to synergistic effects between enhanced gas diffusion pathways, evidenced by a BET surface area of 20.59 m 2 /g, and precise modulation of electron depletion layers via glycine-mediated oxygen vacancy engineering. This work advances a practical paradigm for designing metal oxide semiconductor sensors that harmonize high sensitivity with operational sustainability, highlighting their transformative potential in next-generation environmental monitoring systems.

The demand for wearable monitoring devices in contemporary medicine has significantly increased, especially in dynamic environments where traditional bulky equipment is impractical. Conventional flexible wearable devices or systems suffer from limited air and moisture permeability, lack of stretchability, and high power consumption, which restrict their long-term usage and comfort. Herein, a stretchable and breathable backscattered monitoring system (SBBMS) is introduced, integrated with a fabric substrate. To address the challenges associated with fabric substrate system fabrication and encapsulation, a printing-cutting-transfer technology is proposed. This method enables the creation of unique, low-cost, high-precision, and robust circuit routing and electronic devices on fabric, maintaining high compatibility with commercial surface mounting technology while minimizing sacrifices in breathability. Additionally, a backscatter communication mechanism is designed and implemented to achieve wireless data transmission, which significantly reduces power consumption. Combined with energy management technology and hydrogel batteries, the SBBMS receives safe, multi-source, and eco-friendly energy support. Furthermore, through meticulous design, all modules—including the antenna, circuit, and battery—are made stretchable, providing the system with excellent strain-resistive performance. The approach paves the way for the development of breathable, high-performance, and highly integrated fabric-based wearable systems, catering to specific user groups such as athletes, soldiers, and pilots.

As a new class of two-dimensional transition-metal carbides and carbonitrides, MXenes have been widely used in energy storage, sensing, catalysis, electromagnetic interference shielding and other fields. It is a challenge to simultaneously realize a sensor with extremely high sensitivity, wide detection limits, low power consumption and good mechanical stability. In this work, taking advantage of the high conductivity of MXenes and the porous structure of polyvinyl butyral, a highly sensitive piezoresistive sensor was fabricated. The fabricated MXene/PVB-based sensor exhibits high sensitivity and reliability with a factor of ∼11.9 kPa−1, ∼1.15 kPa−1 and ∼0.20 kPa−1 in the ranges of 31.2 Pa–312 Pa, 312 Pa–62.4 kPa and 62.4 kPa–1248.4 kPa, respectively. The sensor has a wide detection range (∼31.2 Pa to ∼2.205 MPa), low detection limit (6.8 Pa), low detection voltage (0.1 mV), low power consumption (∼3.6 × 10−10 W), fast response time (∼110 ms) and good mechanical stability (over 10 000 maximum-pressure cycles). Moreover, it is demonstrated that the sensor can detect subtle bending and release activities of humans, including arterial pulses and voice signals, which makes it potentially suitable to be used as a wide detection range, highly sensitive and low power consumption piezoresistive sensor. This work provides a new avenue to expand the application of MXene-based flexible pressure sensors with a wide sensing range and ultra-low power consumption.

High-performance stretchable optoelectronic synaptic transistor arrays are key units for constructing and mimicking simulated neuromorphic vision systems. In this study, ultra-low power consumption and low-operation-voltage stretchable all-carbon optoelectronic synaptic thin film transistors (TFTs) using sorted semiconducting single-walled carbon nanotubes (sc-SWCNTs) modified with CdSe/ZnS quantum dots as active layers on ionic liquid-based composite elastomer substrates are first reported. The resulting stretchable TFT devices show enhancement-mode characteristics with excellent electrical properties (such as the record on/off ratios up to 10 5 , negligible hysteresis, and small subthreshold swing), excellent mechanical tensile properties (such as the only 12.4% and 6.4% degradations of the carrier mobility after 20% vertical and horizontal strain stretching), and optoelectronic synaptic plasticity (for the recognition of Morse codes) with ultra-low power consumptions (15.38 aJ) at the operating voltage from −1 to 0.2 V. At the same time, the designed nonvolatile conductance of the stretchable SWCNT optoelectronic synapse thin film transistors (SSOSTFTs) stimulated by UV light and the bending angle are first used to simulate stretchable neuromorphic vision systems (including the functions of the crystalline lens and optic cone cells as bionic eyes) for detecting the atmospheric environment with a record accuracy of 95.1% as a bionic eye.

Electrically responsive photonic crystal (ERPC) based on particle electrophoresis is a promising material for reflective color displays due to its bright and antiglare structural colors, low-voltage tuning, and good compatibility with the electrophoretic display techniques. However, there are still challenges to meet the multifaceted requirements for the display because of the low response sensitivity for most reported ERPCs. Here, we show a SiO 2 /(DEGEEA-Aniline) ERPC with high response sensitivity and ultra-low power consumption. This ERPC possesses a broad color tuning range (220 nm) because the moderate interaction between mixing solvents and SiO 2 particles ensures a low particle assembly concentration and a large space for lattice compression. Meanwhile, this ERPC works at low voltage (0 ∼ 1.3 V) due to the low dielectric constant of the solvents and the enhancement of Coulombic interaction. As a result, the ERPC exhibits a response sensitivity of 169.2 nm/V, which is higher than most reported electrophoretic ERPCs. More importantly, this ERPC merely consumes 1.09 μW/cm 2 in successive color tuning under the precondition of stable and reversible response, which saves 96.5 % of power compared to the traditional SiO 2 /PCb ERPC.

The development of highly sensitive and ultralow-power NO2 sensors is crucial for real-time NO2 monitoring. This study synthesizes tiny SnO2 nanoparticles with enriched oxygen vacancies for use in microelectromechanical system (MEMS) gas sensors, enabling ppb-level NO2 detection at reduced operating temperatures. PVP was used to adjust the particle size and surface oxygen vacancies in the hydrothermal method. The gas sensing performance shows that the 0.75 g PVP-SnO2 exhibited the highest response of 14.7 to 500 ppb NO2 at a low operating temperature of 102 °C, which is 3.2 times higher than that of the 0.00 g PVP-SnO2 sensor under the same conditions. Compared to similar studies, this sensor achieved a high response value and ultralow power consumption of 8.4 mW. The improvement in performance is mainly attributed to N doping and the abundance of oxygen vacancies. This research presents a promising strategy for the development of high-performance, low-energy, real-time NO2 gas sensors.

It is necessary to achieve highly sensitive and low temperature detection of Cl 2 for the protection of the environment and human life and health. How to achieve sensitive detection of Cl 2 at low temperature remains a challenge. The construction of heterojunction is beneficial for promoting carrier transfer, increasing active sites, thus effectively improving sensing performance of materials. In this study, the flower sphere-like Cu 2 O/CuO composite with p-p heterojunction was obtained by using Cu-CPs as precursor followed with sintering treatment. The Cu 2 O/CuO sensor exhibits high response (S=405) to 10 ppm Cl 2 at low temperature (50 °C), the response/recovery time is 50 s/2420 s. At the same time, the Cu 2 O/CuO sensor has a low detection limit (50 ppb) and good long-term stability (60 days). The characterization results, e.g. electron paramagnetic resonance (EPR), O 2 /Cl 2 -temperature programmed desorption ( O 2 /Cl 2 -TPD), X-ray photoelectron spectroscopy (XPS) etc., reveal that oxygen vacancy effectively promotes the increase of surface adsorbed oxygen, the formation of p-p heterojunction not only modulates the electronic properties of Cu 2 O/CuO but also provides abundant adsorption sites for gas. The synergistic effect of the above factors makes Cu 2 O/CuO composite exhibit satisfactory Cl 2 sensing performance.

The monolithic stacked design is expected to solve the challenges of wiring difficulties, complex fabrication processes, and low resolution. However, a photodetector array with low operating voltage that is suitable for imaging applications has not been proposed. Here, a perovskite photodetector array with a monolithic stacked structure is proposed. The CH3NH3PbI3 photodetector has a low power consumption off-state (0 V) and on-state (−2 V) voltage, and the highest responsivity and specific detectivity of 0.39 A/W and 4.53×1012 Jones at 775 nm, respectively. The rise time and decay time are 111 µs and 250 µs respectively. In addition, the imaging application shows high contrast, which provides a simple and effective way to prepare high performance perovskite imaging devices.

Electrically responsive photonic crystals are promising materials for electrophoretic color displays with better brightness and color saturation. However, electric field must always be applied to maintain the specific colors, which brings concerns about the power consumption and signal stability and reversibility. Here, we show an electrically responsive photonic crystal with two stable states at 0 V, which are the colored state or the colorless state with ordered or disordered particle arrangement. The color state can be reversibly switched by applying a short-time electrical field, just like in the case of commercial electrophoretic ink. With optimized recipe and electric field, the photonic crystals encapsulated in the prototype display panel are proved to have potentials in high resolution, multi-color, and greyscale display, which lays down a firm basis for reflective displays with low power consumption and good visibility.
