Electronic devices are components for controlling the flow of electrical currents for the purpose of information processing and system control. Prominent examples include transistors and diodes. Electronic devices are usually small and can be grouped together into packages called integrated circuits. This miniaturization is central to the modern electronics boom.
Integrating electrochemically actuated soft robotics with ultra-flexible microelectrodes enables reversible and gentle wrapping around nerves for high-quality recordings.
Silver nanowires self-assembled on microscale elastomer pores, through in situ phase separation, yield highly elastic porous nanocomposite conductors with ultralow percolation threshold and high stretchability. This material is highly conductive, strain-insensitive and fatigue-tolerant, and holds promise for strain-resilient, wireless, battery-free bioelectronics.
By manipulating the glass transition of the electrolyte, nanometre-resolution electrochemical ion implantation doping can be achieved in various polymeric semiconductors.
Tunable and stable memristors based on single-crystalline entropy-stabilized oxide films grown on epitaxial bottom electrodes can be used to create energy-efficient reservoir computing networks.
Thermal fatigue frequently leads to failure in electronic solder joints. Here, the authors measure and quantitatively explain how microstructure affects thermal fatigue in a ball grid array package and propose optimum microstructures for thermal fatigue resistance.
Interface engineering by local polarization is becoming increasingly important for tunable electronics. Here, authors demonstrate an electric pulse-tuned piezotronic effect in Ag/HfO2/n-ZnO junction, enabling reversible and accurate regulation of barrier height and piezotronic modification range.
The authors report the sweet-spot operation of germanium hole spin qubits, exploring the optimization of the external magnetic field orientation, the g-tensor and its electric tunability, and hyperfine interactions.

Developing circuits for flexible and stretchable devices demands not only high performance but also reliable and predictable components, such as organic thin-film transistors. High-throughput characterization is required to build reliable structure–property relationships, which are critical for the commercialization of new materials.

A synthesis method for large-scale conjugated polymers as well as studies under operational conditions show that research on organic mixed ionic–electronic conductors continues to progress.
