Recently, Fudan University in China has developed a light-weight generator that can be implanted into a human vein. The generator can use the blood flowing in blood vessels to generate electricity autonomously or to be used clinically in the future. It is reported that the generator is based on the carbon nanotubes wound in an orderly arrangement on the polymer core and is responsible for the relative motion by the fibrous fluid nanofoam (FFNG) to obtain the blood flow gradient force through the fiber stratification. R & D personnel said that the high security of the generator, the future or will be used in clinical, for the implantation of medical equipment and technology contribute to a force. At present, R & D personnel have not yet announced the specific power the device can produce. However, R & D personnel said that the device compared to other micro-energy harvesting equipment efficiency greatly improved, the power conversion rate higher than 20%. Although this technology is still in its early stages, they have been implanted in the frog body, the experimental results are satisfactory. In fact, as early as 2011, Swiss researchers developed turbines based on current-flow turbines. In theory, the microturbine can be implanted in the body and generate electricity using blood flow. But in the end found that the device will produce fatal blood clots after implantation in the human body, had to be abandoned due to the high security risk. With the development of implantable medical device technology, there will be more and more areas that can be supported. Although its safety is widely questioned within a certain period of time, we can still believe that these technologies and equipment will surely become an important part of future clinical care. Melt-blown microfibers generally have diameters in the range of 2 to 4 mm, although they may be as small as 0.1mm and as large as 10 to 15mm. Differences between melt-blown nonwoven fabrics and other nonwoven fabrics, such as degree of softness, cover or opacity, and porosity can generally be traced to differences in filament size. The most commonly accepted and current definition for the melt-blown process is: a one-step process in which high-velocity air blows a molten thermoplastic resin from an extruder die tip onto a conveyor or take-up screen to form a fine fibrous and self-bonding web.The melt-blown process is similar to the spunbond process in that both convert resins to nonwoven fabrics in a single integrated process.
