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

Advances in sensors, electrodes and probes are helping to expand the capabilities of brain–computer interfaces.

Each sensor consists of multiple micro-strain gauges containing a stressed layer of silicon dioxide that, after the stress is released by dissolving a sacrificial layer, deforms into a three-dimensional geometry. Thin metal or alloy wires on the strain gauges can measure normal force, shear force and temperature. Because the sensors are made by standard processes used in microelectromechanical system

The researchers — who are based at the Institute of Metal Research in Shenyang China, the University of Science and Technology of China, Peking University and the Shenzhen Institute of Advanced Technology — fabricated micrometre-scale devices using a p-type germanium substrate as the current collector and two separate monolayer graphene emitter and base layers placed on top. Under bias, stimulated

The researchers — who are based at the German Aerospace Center and Technical University of Munich — created a mechatronic design for sensing redundancy, where the number of sensor measurements exceeds the number of possible motions of the robotic arm, and combined it with a momentum-based monitoring method to provide the arm with an intrinsic sense of touch across its surface. Two force-torque sensors

The further development of transistors based on two-dimensional transition metal dichalcogenides faces various issues, starting with the high density of defects typically found in the materials.

The researchers — who are based at Peking University and the Shenzhen-Hong Kong Institute of Brain Science — fabricated the probe by depositing an electrode array on an ultrathin, flexible plastic film and rolling it onto a tungsten microwire to form a cylindrical shank. The interconnecting metal lines of the probe are embedded inside the scroll while the recording electrodes and the input/output pads
