Health Sensors from Graphene Sheets


Medical equipments used for health monitoring suffer from poor adhesion and adaption on the skin surface. Another problem of them is that, they become really bulky and heavy when they are connected to the digital devices and monitors which are used to record and show the data when needed. Researchers from University of Texas at Austin have focused on these problems and made the thinnest and most sensitive skin sensors ever made from wonder material graphene. The graphene sensors designed can precisely measure skin temperature, humidity as well as vital signs from brain, hearth and muscles.


Dr. Akinwande says that electrical and mechanical properties of graphene are underestimated for a long time. He says when single-layer graphene is transferred to human skin, it is almost invisible. As graphene is a flexible material, it does not just stay on the skin as it is placed, it adjusts itself to the surface features of the skin. These adaption properties of graphene gave the material the best sensing properties measured in the first phase EKG, EEG and EMG signals sensing studies.
The advances in the research studies of Dr. Akinwande’s group will not be limited to the advances given above. The group is now planning to add some antenna features to the graphene sensors so that the health data collected by the graphene sensors can be transferred to the doctors and monitored anytime by computers or cell phones. This property can give graphene sensors a vital property, if the sensors are further designed with a logic that whenever a signal reaches or lowers down to a dangerous level for the patient sensors send emergency signals to the doctors or medical institutions.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread that i

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
