In a recent Review article, Joseph Wang and colleagues examined how multimodal wearable sensors could potentially be used to transform healthcare1. Multiple clinical settings were highlighted, including applications in neonatal care, sepsis, diabetes and neurological disease. However, the use of multimodal sensors is also fundamental to the future delivery of surgical care. The early postoperative

For TSMC, Geoffrey Yeap and colleagues report a 2 nm logic platform. Based on gate-all-around nanosheet transistors, it features a scalable copper-based redistribution layer and a flat passivation layer, as well as through-silicon vias. Compared with their previous 3 nm technology node, which was reported at the 2022 IEEE International Electron Devices Meeting, this platform offers an increase in chip

Alexander Gabourie and colleagues — who are based at DeepSim, Inc., the University of California Davis and Stanford University — now report an artificial intelligence (AI)-accelerated thermal model than can work effectively at multiple length scales, from atomistic- to centimetre-scale circuits. The model first uses molecular dynamics to model thermal transport for atomic structures and interfaces

The researchers — who are based at Université Grenoble Alpes — fabricated a 58 × 60-pixel array in which each 70 μm × 70 μm pixel has its own circuit to measure the incident light phase and modulate it via applying an electric field to the liquid-crystal layer. The pixels thus combine the sensing and modulating functions. The co-integration means the system is compact and its optical alignment is naturally

The researchers — who are based at Zhejiang University and Westlake University — used a 2.5D out-of-plane architecture that integrates graphene monolayers on a gold–silicon columnar metasurface. These structures effectively act as individual photodetection units that allow a wide field-of-view to be achieved, similar to the ommatidia in the compound eye of some animals. The team created a 16 × 16-pixel

The researchers — who are based at Tsinghua University, Beijing InnoMem Technologies Co., Ltd and the Beijing Microelectronics Technology Institute — increased the endurance to 107 cycles through device-, circuit- and operation-level optimization. On the device level, the team introduced an interface modulation layer between the hafnium oxide (HfOx)-based resistive switching layer and oxygen exchange

Carolina Aguilar, CEO of INBRAIN Neuroelectronics, tells Nature Electronics about the company’s work on graphene-based brain–computer interfaces and their recent in-patient tests.

Numerous developments in three-dimensional electronics have emerged in 2024, creating new opportunities for conventional and emerging electronic systems.

The researchers — who are based at Nanjing Forestry University, the Nanjing University of Science and Technology, the Northeast Forestry University, South China Agricultural University and Scion — used a transparent wood film substrate and a conductive cellulose-based ink to fabricate flexible electronics that can be bent, folded and rolled. To make the transparent substrate, a delignification process

The researchers — who are based at the Hong Kong University of Science and Technology, the City University of Hong Kong and the École Polytechnique Fédérale de Lausanne — tune the spatial organization of biomolecular inks through electrohydrodynamic aerosolization and in situ electrical poling. Films printed from β-glycine–polyvinylpyrrolidone have a piezoelectric voltage coefficient of 190 × 10−3

The researchers — who are based at the University of Illinois Urbana-Champaign — show that in certain compound semiconductors the defects self-organize into electrically neutral complexes. These push deep-level traps closer to the conduction band edge, where they act as donors. So rather than degrade performance, the CuIn5Se8 field-effect transistors with introduced defects show better performance

By examining how the noise changed at varying temperature and gate biases, the researchers — who are based at New York University, the Korea Advanced Institute of Science and Technology, King Abdulaziz City for Science and Technology, Brookhaven National Laboratory and the National Institute for Materials Science — could attribute the origins of the random telegraph signals to a single trap species

The emergence of artificial intelligence (AI) in military operations is revolutionizing modern warfare — a development that demands robust governance frameworks to mitigate the risks. On 9–10 September 2024, at the Responsible AI in the Military Domain (REAIM) meeting in Seoul, South Korea, a notable advance in military AI governance was achieved. The meeting, which was co-hosted by South Korea, the

Graphene devices have undergone substantial development in the past two decades, but introducing new materials into commercial foundries remains problematic.

The researchers — who are based at Hewlett Packard Enterprise and the University of Michigan — fabricated eight-channel double-microring-resonator avalanche photodiodes with a responsivity of 0.4 A W–1, a dark current of 1 nA and a bandwidth of 40 GHz at −8 V. Each channel has a transmission data rate of 160 gigabits per second and low electrical crosstalk of less than −50 dB. The all-silicon receiver

The memristors consist of two gold electrodes and a 60-nm-thick molecular film of an azo-aromatic complex centred on a ruthenium atom. Precise kinetic control between thermodynamically stable molecular electronic states with different resistances allowed the memristor to access thousands of analogue conductance levels. A 64 × 64 crossbar array of the memristors was used to perform inverse Fourier transforms

The researchers — who are based at Imec and KU Leuven — fabricated transmon-style qubits with aluminium/aluminium oxide/aluminium overlap Josephson junctions using only optical lithography and reactive-ion etching. They characterized 400 qubits and 12,840 Josephson junctions across the entire wafer, reporting a yield of 98.25% and a time-averaged median relaxation time of 75 μs. The ageing of the Josephson
