Nanofluidic memristors that rely on mechanical deformations to modulate ionic conductance can be coupled to form logic circuits, opening a route to ionic machinery that could implement neural networks.
A flexible, biodegradable and self-powered electronic bandage is designed to deliver dual-mode electrical stimulation, which can synergistically accelerate local intestinal wound healing. This approach also shows promise for reducing postoperative complications and could have broad potential for application in other tissues and organs.
Distributed sensing of a dynamic environment is typically characterized by the sparsity of events, such as neuronal firing in the brain. Using the brain as inspiration, an event-driven communication strategy is developed that enables the efficient transmission, accurate retrieval and interpretation of sparse events across a network of thousands of wireless microsensors.
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.
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.
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.
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.
An approach to soft electronics that is inspired by the emergence process of butterflies can be used to create devices that can recover from crumpling.
The planar structure of thin-film piezoelectric resonators limits the integration of multiband processors on a single chip. A three-dimensional nanomechanical resonator based on conformal ferroelectric gates to excite resonance in scalable silicon fins is shown to enable multiband integration on a single chip and to facilitate densification of processors for ultrawide-band wireless communication.
