Special Issue Information

Dear Colleagues,

Information materials, a group of functional materials used for the purposes of detection, transmission, storage, and display, are the cornerstone of the modern information society. In particular, emerging new materials and novel device structures have been considered for next-generation information technology. The scope is internationally broad and falls within Materials Science, Electrical Electronics, Energy Fuels, and Telecommunication Categories. Due to the complexity of issues, therefore particularly welcomes innovative interdisciplinary research with wide impact.

This Special Issue will mainly address comprehensive reviews and original research articles featuring important and recent developments in information detection materials and devices. Materials and sensors with functions such as photosensitive, piezoelectric, and electromagnetic functions are encouraged. This Special Issue will also serve as a platform for researchers working in information materials to communicate their findings and visionary reviews as well as bring the materials science and information technology together to contribute to this emerging field. In particular, serving as a high-quality platform for scientists working in a wide variety of research areas including information technology, energy materials, materials sciences and engineering, applied physics and chemistry, and so on, to communicate their findings and opinions.

Authors who are experts in these areas or are interested in this emerging topic are welcome to contribute by 30 May 2022. All papers are peer-reviewed and will be published online as soon as possible when accepted.

Additive manufacturing technologies allow the fabrication of smart objects, which are made up of a dielectric part and an embedded sensor able to give real-time feedback to the final user. This research presents the characterization of a low-cost 3D-printed strain sensor, fabricated using material extrusion (MeX) technology by using a conductive material composed of a polylactic acid (PLA)-based matrix doped with carbon black and carbon nanotubes (CNT), thus making the plastic conductive. A suitable measurement set-up was developed to perform automatic characterization tests using a high repeatability industrial robot to define either displacement or force profiles. The correlation between the applied stimulus and the variation of the electrical resistance of the 3D-printed sensor was evaluated, and an approach was developed to compensate for the effect of temperature. Results show that temperature and hysteresis affect repeatability; nevertheless, the sensor accurately detects impulse forces ranging from 10 g to 50 g. The sensor showed high linearity and exhibited a sensitivity of 0.077 Ω g−1 and 12.54 Ω mm−1 in the force and displacement range of 114 g and 0.7 mm, respectively, making them promising due to their low cost, ease of fabrication, and possible integration into more complex devices in a single-step fabrication cycle.

This study examined the electromechanical characteristics of piezoelectric materials, which constitute a compact renewable energy source; these materials can convert mechanical energy (such as pressure or a cumulative impact) in the form of mechanical stress to electricity. This study further explored systems that require moderate energy and utilize piezoelectric materials to create an energy-generating floor. The electrical characteristics of these piezoelectric materials were studied, including the feasibility of installing them as a power source for road lighting, particularly cycling lanes. Furthermore, the effects of riders’ weights and cycling speeds were investigated. The results indicate that the electric power generated is adequate for the installation of these materials and can thus help improve visibility in the event of insufficient lighting. Full article

The authors report that polypyrrole (PPy) films with large area and high crystalline quality have been achieved using an interfacial chemical oxidation method. By dissolving different reactants in two immiscible solvents, the PPy is synthetized at the interface region of the two solutions. The PPy films have sharp XRD diffraction peaks, indicating that the molecular chains in the film are arranged in a high degree of order and that they reflect high crystalline quality. High crystal quality is also conducive to improving electrical conductivity. The conductivity of the as prepared PPy film is about 0.3 S/cm, and the carrier mobility is about 5 cm2/(Vs). In addition, the biggest advantage of this method is that the prepared PPy film has a large area and is easy to transfer to other substrates. This will confidently broaden the application of PPy in the future. Full article
