An AI-assisted smart textile can be used to record, model and understand human–environment interactions.

Programmable metasurfaces can be used to encode wireless signals between users at different locations.

Changes in the anomalous Hall resistance of a single device comprising a Ta/CoFeB/MgO heterostructure can be used to probe three-dimensional magnetic fields with high sensitivity and good linearity.

A hydrogel composite that consists of micrometre-sized silver flakes suspended in a polyacrylamide–alginate hydrogel matrix exhibits a high electrical conductivity of over 350 S cm⁻¹ and a low Young’s modulus of less than 10 kPa.

Large-scale sensing textiles that can conform to arbitrary three-dimensional geometries and are created through digital machine knitting of piezoresistive fibres can be used to record, monitor and learn human–environment interactions.

Laser-induced terahertz emission, and time-of-flight measurements of the terahertz pulse, can be used to non-invasively characterize through-silicon vias, which are required for three-dimensional CMOS integration.

Multiple field-programmable gate arrays can be networked to create clustered, scalable architectures that can be used to run partitioned simulated bifurcation algorithms for solving non-deterministic polynomial-time (NP)-hard problems.

Space–time-coding digital metasurfaces can be used to implement secure and low-cost space- and frequency-division multiplexing in a dual-channel wireless communication system.
