Using carbon nanotube transistors, stretchable temperature sensor circuits can be designed that suppress strain-dependent errors and achieve a measured inaccuracy of only ±1 °C within a uniaxial strain range of 0–60%
The direction of strain in a material can be detected using flexible giant magnetoresistive devices that consist of a strain-sensitive free layer and a strain-insensitive pinned layer.
The generation of a spin current by the anomalous Hall effect is observed by measuring the modulation in the ferromagnetic resonance linewidth of CoFeB/Cu/NiFe trilayer films.
Passive isolators that offer unitary transmission, infinite isolation and large non-reciprocal intensity range can be created by combining Fano and Lorentzian nonlinear resonators, separated by suitably designed delay lines.
Leaky integrate-and-fire artificial neurons based on diffusive memristors enable unsupervised weight updates of drift-memristor synapses in an integrated convolutional neural network capable of pattern recognition.
Memristors that offer good thermal stability, which is lacking in traditional memristors, can be created from a van der Waals heterostructure composed of graphene/MoS2–xOx/graphene.
In a human pilot trial, ingestible electronic capsules, which can sense oxygen, hydrogen, and carbon dioxide gas in the gut, have been shown to be capable of monitoring changes in a person’s diet.
The detection of force-induced displacements within compact MEMS (microelectromechanical system) devices can be used to measure electric field strength without significant field distortion.
On-chip inductors made from intercalated multilayer graphene can offer both small form-factors and high inductance values, without comprising performance, making them potentially suitable for the development of ultra-compact wireless communication systems.
Deep subsurface defects in three-dimensional NAND flash memory devices can be identified by exploiting the inherent hyperbolic metamaterial structure of the devices.
Using field-effect transistors made from carbon nanotube films, five-stage ring oscillators can be fabricated that exhibit an oscillation frequency of up to 5.54 GHz.
Memristor crossbars with array sizes of up to 128 × 64 cells are capable of analogue vector-matrix multiplication and can be used for signal processing, image compression and convolutional filtering.
The external and internal mechanical motion of a person can be directly modulated onto multiplexed radio-frequency signals using near-field coherent sensing, allowing vital signs such as heart rate, blood pressure and respiration rate to be monitored without direct contact to the skin.
