A complete in-memory hyperdimensional computing system, which uses 760,000 phase-change memory devices, can efficiently perform machine learning related tasks including language classification, news classification and hand gesture recognition from electromyography signals.
A microstructured liquid metal fibre can be used as a soft transmission line probe for reflectometry, allowing electronic textiles to be created that can decipher convoluted mechanical stimulation.
The monolithic integration of electronic and plasmonic technologies can be used to create electro-optic transmitters capable of symbol rates beyond 100 GBd.
Resistive switching in atomically thin sheets of hexagonal boron nitride can be used to create analogue switches for applications in communication systems across radio, 5G and terahertz frequencies.
A neurotransistor made from a silicon nanowire transistor coated by an ion-doped sol–gel silicate film can emulate the intrinsic plasticity of the neuronal membrane.
A parity–time symmetric system based on two coupled acoustic resonators in a lithium niobate platform can achieve non-reciprocal propagation of acoustic waves.
A single ferroelectric field-effect transistor, which is made from ferroelectric hafnium oxide, can be used as a full-wave rectifier and frequency doubler.
An impedance measurement technique based on dielectric excitation in oxide semiconductors can provide a highly linear sensing signal over a wide range of gas concentrations.
Semiconducting metal oxide gas sensors with a linear response, broad dynamic range and high baseline stability can be created with the help of a dielectric excitation technique.
This Review Article examines the development of non-magnetic non-reciprocal electronics with a focus on devices based on temporal modulation, including approaches based on temporal modulation of permittivity and conductivity, as well as superconducting components for applications in quantum computing.
The power consumption and carbon emissions of wireless communication networks are expected to substantially increase in the 5G era. The communications industry must therefore develop strategies to optimize the energy efficiency of 5G networks, without compromising spectrum efficiency.
