A low-power radio-frequency multiplexing cryo-electronics system, which is based on complementary metal–oxide–semiconductor technology, can operate below 15 mK and provide the control and interfacing of superconducting qubits with minimal cross-coupling.
A machine-learning-based model can be used to perform atomistic simulations of phase changes along the germanium–antimony–tellurium composition line, up to a full-size memory device model that contains half a million atoms.
Acoustically driven spin control of silicon monovacancies can be used to measure the resonant properties and dynamical strain distribution in lateral overtone bulk acoustic resonators.
By monolithically integrating organic light-emitting diodes (OLEDs) with complementary metal–oxide–semiconductor (CMOS) technology, implantable optogenetic probes can be created to selectively address individual neurons.
A neuromorphic biosensor that consists of a sensor input layer, an array of organic neuromorphic devices (forming a hardware neural network) and an output classification layer can be trained on the chip to classify a model disease and then retrained on the chip by switching the sensor input signals.
A bioelectronic patch that is composed of three layers—an ionically conductive tissue adhesive, a viscoelastic networked film and a fatigue-resistant conducting composite—is capable of instantaneous and conformable tissue adhesion on a heart for precise cardiac monitoring and feedback stimulation.
Arbitrary problem graphs with up to 48 nodes can be efficiently and quickly solved by directly mapping onto a fully connected Ising chip that uses complementary-metal–oxide–semiconductor-based oscillators.
A wireless communication approach for neural implants that is based on electro-quasistatic signalling can offer end-to-end channel losses of only around 60 dB at a distance of around 55 mm.
A platform that integrates a ferroelectric gate and two-dimensional heterostructure of tungsten diselenide and tin diselenide can operate in various gating modes, demonstrating typical transistor, steep-slope transistor and synaptic behaviours.
A clock and optical frequency synchronization technique, enabled by frequency comb and signal processing techniques, can provide users with guaranteed bandwidth and low latency for time-critical applications.
Metal halide perovskites are of increasing use in applications beyond conventional photovoltaics, from flexible solar cells for wearable devices to field-effect transistors for unconventional computing.
High-performance lead-free perovskite thin-film transistors that have low-defect channel–dielectric interfaces can be fabricated using a cation substitution method.
