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.

Improving Dialysis Process with Graphene

Researchers from Mechanical and Electrical Engineering Departments of MIT recently showed that graphene is a powerful material candidate for use in the dialysis systems (such as hemodialysis machines in medical institutes for filtering human blood). In order to prepare graphene as a dialysis material, researchers used a procedure opposite to the general treatments that nanotechnology people use. Dialysis is a process of filtering different solutions such as human blood by a membrane in order to remove waste molecules, drugs, chemical residues from the solution. In some cases, the process can be used for purification of chemicals or isolation of different molecules for medical diagnosis. It is an essential process for scientists especially in the medical operations.

Rundown about Silicon Oxide Wafer

The main insulating material used in micro-technology is Silicon Dioxide, which in chemical symbols is written as SiO2. In semiconductor technology, SiO2 thin film layers are mainly used as dielectric material film in transistors, capacitors (DRAM) or flash-memories. Silicon Oxide Wafers are produced using crystallization, solid state and other ultra-high purification processes such as sublimation. This process forms a cylindrical ingot, which is then sliced and polished to form wafers. Thermal oxide is a kind of "grown" oxide layer, compared to CVD deposited oxide layer, it has a higher uniformity, and higher dielectric strength, it is an excellent dielectric layer as an insulator . In most silicon- based devices, thermal oxide layer play an important role to pacify the silicon surface to act as doping barriers and as surface dielectrics. The simplest way to produce an insulating silicon oxide layers (SiO2) on silicon wafers is to oxidize silicon with oxygen, which ...
