“…Because of their good electrical response to the temperature variations, CNTs became a serious candidate as an emerging material to provide solutions for the future temperature sensors development. Both single and multiwall CNTs, having either metallic and semiconductor behavior, have been reported as temperature sensors [11,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55].…”

“…There are a few structure designs, fabricated in batch assembly processes [59], but most of CNT-based sensors are produced in a serial assembly process, resulting in a low number of products. Over time, several assembling methods have been developed, including: direct growth on the substrate by chemical vapor deposition (CVD) process [29,30,31,32,33,34,53,54,55];thin films obtained by gluing [37,38], printing [35,36], filtration over a membrane [51,52], spraying [49,50,60];drop-casting deposition from a solution followed by a dielectrophoresis (DEP) procedure [39,40,41,46,47,61,62]. …”

Accurate measurement of temperatures with low power consumption with the highest sensitivity and smallest possible elements is still a challenge. The thermal, electrical, and mechanical properties of carbon nanotubes (CNTs) have suggested that their use as a very sensitive sensing element will allow the creation of different sensors, far superior to other devices of similar size. In this paper, we present a short review of different constructive designs of CNTs based resistive sensors used for temperature measurement, available in literature, assembled using different processes, such as self-assembly, drop-casting from a solution, thin films obtained by gluing, printing, spraying, or filtration over a special membrane. As particular cases, temperature sensors obtained from CNT-polymer nanocomposite structures, CNTs filled with uniformly dispersed Fe3O4 nanoparticles or with gallium, and carbon nanotube wires (CNWs) hybrids are presented. Using these preparation procedures, mixtures of CNTs with different dimensions and chirality, as well as with a variable level of impurities and structural defects, can be produced. The sensors’ performance charts are presented, highlighting a number of aspects regarding the applicability of CNT structures for temperature measurement ranging from cryogenic temperatures to high temperatures, the limitations they have, their characteristics and advantages, as well as the special situations that may arise given the particular structure of these new types of materials, together with basic relationships and parameters for CNTs characterization. Further research will be required to develop the techniques of manipulating and depositing individual CNTs on supports and electrodes for the development of temperature sensors.

Structural improvement of a bio-inspired 3D globular carbon foam by a continuously thermal treatment: A comprehensive study

The manufacturing of a 3D interconnected globular carbon foam, called Globugraphite, is based on the replication of the zinc oxide (ZnO) template morphology by carbon with simultaneous removing of the template material in the chemical vapour deposition (CVD -replica CVD (rCVD)) process. The growth mechanism of the presented carbon foam affected the formation of defects at the atomic level which leads in the following to graphitic pieces instead of layers. This substructure influences properties, such as electrical conductivity of the carbon foam negatively. By undergoing a temperature treatment at 1600°C, 1800°C, 2000°C and 2200°C in a protective gas atmosphere the carbon structure heals at the atomic level. The connection of the sp 2 /sp 3 graphitic pieces to graphitic sp 2 layers due to the thermal annealing is analysed via transmission electron microscopy (TEM) observation and Raman spectroscopy. Based on these analysis methods a model of the graphitization progress is created which explains the clearly increase of the electrical conductivity and the oxidation temperature.

Thermophysiological comfort in humans is sought universally but seldom achieved due to biological and physiological variances. Most people in developed parts of the world rely on central heating and cooling systems to achieve thermophysiological comfort which is highly energy-intensive, inefficient, and rarely satisfactory. A potential solution to this issue is a wearable personal thermal comfort system (PTCS) consisting of textile-based temperature and moisture sensors, that can sense the environment and physiology of the wearer, combined with thermal and moisture responsive actuators, and/or heating/cooling devices to provide an individualized thermal environment. Moving thermal regulation away from the built environment to the microclimate surrounding the human body with the use of textiles has the This article is protected by copyright.

Such a system may employ thermal comfort models and leverage the Internet of Things (IoT) and machine learning (ML) to understand individuals' comfort requirements in the current environment. Herein, the current state of textile-based active and passive thermophysiological comfort systems/technologies is summarized, including their environmental impact, major thermal comfort models, and factors influencing comfort (such as heat and moisture transfer). Also, active and passive textile-based devices (sensors, actuators, and flexible heating/cooling devices) that may be incorporated into a textile-based wearable PTCS are comprehensively discussed with an emphasis on their advantages, limitations, and future prospects.
