Materials for devices are materials employed in devices because of their particular properties, such as electrical, thermal, magnetic, mechanical, ferroelectric or piezoelectric properties. Examples of materials for devices are polymers, oxides, semiconductors and liquid crystals.
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.
Inspired by fireflies, a bimodal information indication system using a photochemical afterglow material within a photonic crystal matrix is developed to display both static and changing information, such as sample type and degree of degradation.
To measure temperatures close to absolute zero, authors developed a kind of composite phase diamond (CPD) that can measure temperature at the millikelvin level, making it a promising candidate for next–generation cryogenic temperature sensors.
We report on a near-zero-power flexible heat pump that uses both electrocaloric and electrostrictive properties of a tailored polymer to create a chip-scale refrigerator device.
A molecular design strategy for reducing the vibration-induced non-radiative losses in emissive organic semiconductors is realized by decoupling excitons from high-frequency vibrations.
The micro-thermoelectric coolers face challenges in high-performance material preparation and high-density device integration. Here, the authors combine Bi2Te3-based film prepared by powder direct molding with micro-thermoelectric cooler integrated via phase-change batch transfer.
Magnetoelectric (ME) microelectromechanical and nanoelectromechanical systems (M/NEMS) are vital for addressing the challenges of the internet of things (IoT) networks in size, energy efficiency and communication. This Review delves into ME materials and M/NEMS for IoT applications, such as sensing and communication technologies.

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.
