“…Kuo et al (67) used nanoparticles as catalyst to grow CNTs bridging electrodes and fabricate a temperature sensor. In their work, the resistance of a CNT is in linear relationship with temperature, therefore the temperature can be determined by monitoring the resistance change of CNT.…”

Nanoscale novel devices have raised the demand for nanoscale thermal characterization that is critical for evaluating the device performance and durability. Achieving nanoscale spatial resolution and high accuracy in temperature measurement is very challenging due to the limitation of measurement pathways. In this review, we discuss four methodologies currently developed in nanoscale surface imaging and temperature measurement. To overcome the restriction of the conventional methods, the scanning thermal microscopy technique is widely used. From the perspective of measuring target, the optical feature size method can be applied by using either Raman or fluorescence thermometry. The near-field optical method that measures nanoscale temperature by focusing the optical field to a nano-sized region provides a non-contact and non-destructive way for nanoscale thermal probing. Although the resistance thermometry based on nano-sized thermal sensors is possible for nanoscale thermal probing, significant effort is still needed to reduce the size of the current sensors by using advanced fabrication techniques. At the same time, the development of nanoscale imaging techniques, such as fluorescence imaging, provides a great potential solution to resolve the nanoscale thermal probing problem.

“…Short length CNTs are mainly used as the channel of CNT field effect transistors (CNT-FETs) (1)(2)(3). Moderatelylong and long-CNTs are largely used for the applications like CNT-based sensors (4)(5)(6)(7)(8)(9), interconnects (10)(11)(12)(13), and infrared emitters (14,15). While in most of the published reports room temperature analysis of CNTs has been carried out, in some applications knowing the electrical behavior of CNTs at higher temperatures is also needed.…”

“…For example, the response of gas sensors is generally measured at various temperatures. Although some of the researchers have experimentally investigated the temperature dependence of resistance or conductance in moderately-long or long CNTs (9,(16)(17)(18)(19), there are only a few theoretical works in this field (11,20,21). As an example, Naeemi and Meindl (11) physically modelled the temperature coefficient of resistance (TCR) for metallic single wall CNTs (m-SWCNTs) and multi wall CNTs (MWCNTs).…”

We present compact analytic formulas with appropriate accuracy for the resistance of semiconducting and metallic single wall carbon nanotubes (s-SWCNTs and m-SWCNTs) as functions of their diameters and lengths, and the temperature. Based on these relations, we investigate the dependence of their resistances and corresponding temperature coefficients on the SWNTs' diameters. Taking the tube to tube random variation in diameters of horizontally-aligned SWCNTs, we calculate the equivalent resistances and effective TCRs for arrays of both s-SWCNTs and m-SWCNTs.

Abstract-These Wind turbines convert mechanical energy into electrical energy for storage and consumption. Pressure transducers are important in reflecting pressures within the hydraulic cylinders; they can provide continuous and reliable operation that enhances the reliability and efficiency of the overall system. Monitoring high temperature fluctuation will be necessary for the resolution and efficiency of the system. An integrated sensor system should be important for monitoring the tower vibration for bending, crack formation, and wave vibration.Smart nanotechnology materials have been recently utilized in sensing applications. Carbon nanotube (CNT) based SoC sensor systems have potential applications in various fields, including medical, energy, consumer electronics, computers, and HVAC (heating, ventilation, and air conditioning), among others.In this study, a nanotechnology multisensory system was designed and simulated using Labview Software. More emphasis are given to both pressure and temperature sensors that serve as transducers for the power mills. The mathematical models were developed for sensing three physical quantities: temperature, gas, and pressure. Four CNT groups on a chip (two for gas sensor, one for temperature, and a 4 th one for pressure) were utilized in order to perform sensing multiple parameters. The proposed fabrication processes and the materials used were chosen to avoid the interference of these parameters on each other when detecting one of them. The simulation results were translated into analog voltage from Labview software, transmitted via Bluetooth network, and received on desktop computers within the vicinity of the sensor system. The mathematical models and simulation results showed as high as 95% accuracy in measuring temperature, and the 5% error was caused from the interference of the surrounding gas. Within 7% change in pressure was impacted by both temperature and gas interference.Index Terms-Wind energy, nanotechnology, pressure sensors, temperature sensors, SOC.
