A measurement scheme in which current is injected simultaneously into two disconnected perimeters of a multi-terminal Corbino device can be used to increase the robustness of a zero-magnetic-field quantum anomalous Hall resistor, thus extending its operating range to higher currents.
Using an intrinsically stretchable nanocomposite of quantum dots, an elastomer and a hole transport polymer as an emissive layer, stretchable light-emitting diodes can be fabricated that exhibit high brightness even under 50% strain.
Photo-responsive metal halide perovskite light-emitting diodes can be used to create a multifunctional display that can function as a touch screen, ambient light sensor and image sensor.
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.
A biodegradable electronic bandage that applies pulsed and d.c. electrostimulation can accelerate the healing of intestinal wounds in mice via transfection of cells and stimulation-induced secretion of healing factor from those cells.
Wearable sweat sensors could be used to monitor patients with heart failure, providing a route to personalized and automated patient management in hospitals and at home.
A scalable communications protocol for transmitting spike-train data generated from multiple microchip sensors can be used with spiking neural network models for brain–machine interface and biosensing applications.
Nanofluidic devices with a large entrance asymmetry can function as memristive switches—operating on the second timescale and with a conductance ratio of up to sixty—and can be assembled into basic logic circuits.
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.
