It is shown that 1,024 organic light-emitting diodes can be densely integrated with silicon complementary metal–oxide–semiconductor control circuitry to create neural probes that can selectively activate neurons with millisecond-level timing.
An autonomous wearable device that is capable of monitoring sweat for extended periods of time could help collect data for the development of personalized medicine.
The remarkable properties of graphene nanoribbons are promising for use in quantum technologies. To create quantum devices, however, individual nanoribbons must be contacted. This crucial step has now been demonstrated using single-walled carbon nanotubes as electrodes.
Individual graphene nanoribbons synthesized by an on-surface approach can be contacted with carbon nanotubes—with diameters as small as 1 nm—and used to make multigate devices that exhibit quantum transport effects such as Coulomb blockade and single-electron tunnelling.
Organic semiconductor and colloidal quantum-dot-based thin-film image sensors show reduced noise, dark current and image lag when a pinned photodiode pixel structure, similar to those in silicon-based image sensors, is used.
A skin-conformable system that is worn on the finger, and integrates optical sensors with memristors, can accurately classify finger-written inputs in three-dimensional space.
An integrated artificial synapse array and light-responsive motion sensor can be conformably attached to a finger and used to track finger motion in three-dimensional space.
A multicore analogue in-memory computing chip that is designed and fabricated in 14 nm complementary metal–oxide–semiconductor technology with backend-integrated phase-change memory can be used for deep neural network inference.
Magnetic fluctuations and random telegraph noise in vertical tunnelling heterostructure devices composed of vanadium-doped tungsten diselenide sandwiched between graphene layers can be tuned using an electric bias.
High-tech industries power the modern digital world, but their supply chains are particularly vulnerable to geopolitical and economic disruption. Urgent action is needed to improve supply-chain resilience.
This Perspective explores the development of metal halide perovskite transistors, examining the properties of halide perovskites and key perovskite transistors, and considering the challenges that exist in developing next-generation electronics and circuits using these devices.
Programmable metasurfaces can be used for wireless attacks at the physical layer, highlighting potential security threats for next-generation wireless networks.
Piezoelectric transducers based on ferroelectric hafnia–zirconia–alumina can be used to create nanoelectromechanical resonators that operate between 0.4 and 17.3 GHz and have an on/off isolation of 37 dB.
