Three-dimensional liquid metal structures can be created by manipulating ductile gallium–indium alloy wires that are then encapsulated in an elastomer and heated to recover their fluidity, and can remain in a liquid state for a range of temperatures due to a supercooling effect.

By engineering the upper and lower surfaces of micro-light-emitting-diode chips to have different van der Waals forces, hundreds and thousands of chips can be accurately aligned on substrates and used to create active-matrix displays.

Three-layer heterostructures consisting of an indium gallium arsenide semiconducting film, a lithium niobate piezoelectric film, and a silicon substrate can be used to create acoustoelectric amplifiers that operate at gigahertz frequencies with large non-reciprocal gain and low noise in continuous operation.

Long-range wireless data links can be created by combining a software-defined digital signal processing back end with on-chip high-power terahertz signal sources and broadband frequency mixers based on Schottky diode technology.

A nanomesh sensor that is directly printed on a person’s hand and is coupled with an unsupervised meta-learning framework can provide user-independent and data-efficient recognition of different hand tasks.

Low current densities can be used modulate the magnetism of Co₃Sn₂S₂—a magnetic Weyl semimetal—via spin-transfer-torque-assisted domain wall motion.
