“…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.

“…Multiplexed arrays of nanowire sensors can be functionalized with different sensing affinities using microspotting methods used in biomolecular arrays, or by Dip Pen Nanolithography for other higher density systems. Nanosensors have already been made for rapid detection of metal ions [453], gases [454], biomolecules [455], temperature [456,457] and mechanical strain [458].…”

Metals and their alloys have been widely used in all aspects of science and engineering. However the science of nanotechnology is driving newer demands and requirements for better performance of existing materials and also at a higher level of precision. This is naturally presenting complicated demands on the surface of these metals with a need for surface modification. Self Assembled Monolayers (SAMs) are nanosized coatings that present the most efficient method of carrying out surface modification. Alkylsilanes are silicon based SAMs which are compatible with the majority of metals and alloys. These nanocoatings can serve primary functions such as surface coverage, etch protection and anti corrosion, along with a host of other secondary chemical functions because of their amphiphilic nature. We present a brief introduction to surface modification of metals and alloys followed by a detailed description of silane based nanocoatings and their applications in technology. Then a look at the engineering aspects of these coatings in terms of patterning techniques is presented along with a discussion of the applications of patterned SAMs.

“…Carbon nanotubes (CNTs) have been shown to have various potential applications [1][2][3][4][5][6] and have attracted signicant interest due to their very attractive mechanical and electrical properties. Recent studies have shown that carbon nanotubes (CNTs) can be used as temperature sensors [7][8][9][10][11][12] because the extremely small size of the CNT can provide accurate measurements at nanoscale size and reduce the possibility of disturbing the neighboring environment, which is very important in a complicated thermal ow system. The reported CNT-based temperature sensors can be categorized into thermal expansion and thermal resistance according to their different working principles.…”
