Using commercial 0.8-μm metal-oxide thin-film transistor technology, a flexible processor chip can be built that has hardwired parameters for machine learning and is capable of smart applications such as odour recognition.
A memristor-based annealing system that uses an analogue neuromorphic architecture based on a Hopfield neural network can solve non-deterministic polynomial (NP)-hard max-cut problems in an approach that is potentially more efficient than current quantum, optical and digital approaches.
Fixed magnetic skyrmions that are stabilized without any external magnetic field can be manipulated using an electric field, providing an approach that could be used to create compact and energy-efficient devices
Wearable yarn-based stretchable sensor arrays, combined with machine learning, can be used to translate American Sign Language into speech in real time.
A homojunction device made from two-dimensional tungsten diselenide can be used to create circuits that exhibit multifunctional logic and neuromorphic capabilities with simpler designs than conventional silicon-based systems.
By integrating a single monocentric lens with a hemispherical silicon nanorod photodiode array, a wide-field-of-view camera is created that offers low optical aberration, deep depth of field and simple visual accommodation.
Modern cars have an array of sensors that allow different objects to be recognized, including large and small animals. They thus have the potential to become a tool for monitoring biodiversity and improving driver safety. But to achieve this various challenges in computing, communications and privacy need to be addressed.
The adoption of autonomous vehicles will depend on the public’s trust in the technology. To establish such trust, it is important to understand the actions of different road users, and their reactions to the vehicles.
A fibre with liquid-metal core and soft outer shell can be woven into textiles and used to sense multiple compression and stretching events simultaneously.
A clock synchronization method, which is based on optical clock distribution and clock phase caching, can provide subnanosecond clock and data recovery times for fast optical switching in large-scale data centre networks using off-the-shelf commercial transceivers.
Electrostatic gating can be used to modulate the magnetic anisotropy of chromium germanium telluride, a layered ferromagnetic semiconductor, and increase its Curie temperature to 200 K.
A magnetoresistance effect that occurs in a platinum layer deposited on a magnon junction consisting of two insulating magnetic yttrium iron garnet layers separated by an antiferromagnetic nickel oxide spacer layer could be used to create spintronic and magnonic devices that are free from Joule heating.
A bioinspired machine-learning architecture can combine visual data with data from stretchable strain sensors to achieve human gesture recognition with high accuracy in complex environments.
Using a solution-based deposition technique, carbon nanotube field-effect transistors can be fabricated in a commercial silicon manufacturing facility and a high-volume commercial foundry, demonstrating uniform and reproducible transistor fabrication across industry-standard 200 mm wafers.
