This Review examines the development of electrical reservoir computing, considering the architectures, physical nodes, and input and output layers of the approach, as well as performance benchmarks and the competitiveness of different implementations.
Polycrystalline films of the non-toxic element bismuth exhibit a room-temperature surface nonlinear Hall effect, which could make devices based on topological quantum effects more practical.
A two-dimensional perovskite, Sr2Nb3O10, can be integrated with a range of other two-dimensional materials and act as a photoactive high-κ dielectric in the resulting phototransistors.
Micropatterning of organic semiconductors by electron-beam exposure can be used to create vertical organic electrochemical transistor arrays and complementary logic circuits with densities of up to 7.2 million transistors per cm2.
Developments in universal chiplet interconnect express could be used to construct three-dimensional system-on-chip design architectures that offer power, performance and reliability characteristics approaching or exceeding those of current monolithic system-on-chip designs as the bump interconnect pitch approaches 1 µm.
An approach to dynamically control the photoresponsivity of pixels in a computational sensor based on local image gradients enables the precise and robust detection of edge features of targets in dim light conditions from a single image capture.
Tapes whose adhesive force is controlled by ultraviolet illumination can be used to cleanly transfer large-area graphene, molybdenum disulfide and other two-dimensional materials with a low thermal budget and using no organic solvents.
Large-area two-dimensional materials can be transferred at low temperatures and without solvents using conformable tapes whose adhesive force varies with ultraviolet illumination, allowing transfer to various planar and non-planar substrates.
This Review explores the development of ingestible electronics and provides a step-by-step guide for the design of ingestible electronic capsules at the system level.
The correlated optoelectronic characteristics of multi-terminal mixed-dimensional graphene–germanium heterostructure devices can be used for the accurate detection and robust tracking of dim targets.
Polycrystalline thin films of elemental bismuth exhibit a room-temperature nonlinear transverse voltage due to geometric effects of surface electrons that is tunable and can be extended to efficient high-harmonic generation at terahertz frequencies.
An electronic skin that is capable of long-term monitoring of vital signs and molecular biomarkers in sweat can—with the help of machine learning—be used to classify stress responses with high accuracy and predict state anxiety levels with high reliability.
By transferring laser-induced graphene to a hydrogel film at cryogenic temperatures, stretchable graphene–hydrogel interfaces can be created for application in wearable and implantable electronics.
