Unique chemical, physical, and biological features of carbon nanotubes make them an ideal candidate for myriad applications in industry and biomedicine. Carbon nanotubes have excellent electrical and thermal conductivity, high biocompatibility, flexibility, resistance to corrosion, nano-size, and a high surface area, which can be tailored and functionalized on demand. This review discusses the progress and main fields of bio-medical applications of carbon nanotubes based on recently-published reports. It encompasses the synthesis of carbon nanotubes and their application for bio-sensing, cancer treatment, hyperthermia induction, antibacterial therapy, and tissue engineering. Other areas of carbon nanotube applications were out of the scope of this review. Special attention has been paid to the problem of the toxicity of carbon nanotubes.

Carbon nanotubes have been the focus study in composite health monitoring fields due to its better performances and excellent mechanical property. Yet, the performance for multi-direction strain monitoring of the carbon nanotube film sensor has not been concerned. Therefore, this article focuses on the strain monitoring with the circular carbon nanotube film sensor which exhibits the characteristics for multi-direction strain measurement. The carbon nanotube film is fabricated through agitation, sonication, centrifugation, and vacuum filtration. Using the molding machine, the circular carbon nanotube film senor and the rectangular carbon nanotube film sensor are surface bonded with composite laminates, respectively, to compare the multi-direction strain monitoring characteristics. With the prepared laminates, the stretching tests are committed at 0°, 30°, 60°, and 90°using the universal tensile machine. Experimental results of the circular sensor show the steady sensing coefficients that fluctuate between 59.51676 and 60.9273 at different degrees. By comparison, the rectangular sensor presents different sensing coefficients from vertical stretching test and horizontal stretching test. Therefore, the circular carbon nanotube film exhibits multi-direction strain monitoring that can serve as an efficient tool for structural health monitoring of composite structures.

“…In recent years, nanocomposite sensors [ 22 , 23 , 24 ] have become a new research hotspot. In particular, nancomposites which leverage conductive materials embedded in flexible substrates have shown promise in applications which measure the daily activities of the human body and convert them into electrical signals which can be digitally analyzed [ 25 , 26 , 27 ]. One disadvantage of virtually all of these sensors has been a low resting resistance [ 28 ].…”

Sitting posture is the position in which one holds his/her body upright against gravity while sitting. Poor sitting posture is regarded as an aggravating factor for various diseases. In this paper, we present an inverse piezoresistive nanocomposite sensor, and related deciphering neural network, as a new tool to identify human sitting postures accurately. As a low power consumption device, the proposed tool has simple structure, and is easy to use. The strain gauge is attached to the back of the user to acquire sitting data. A three-layer BP neural network is employed to distinguish normal sitting posture, slight hunchback and severe hunchback according to the acquired data. Experimental results show that our method is both realizable and effective, achieving 98.75% posture identification accuracy. This successful application of inverse piezoresistive nanocomposite sensors reveals that the method could potentially be used for monitoring of diverse physiological parameters in the future.
