Within the field of medicine, the presence of any type of cancer is not a simple task, is required of studies to confirm it, which involves time and sometimes it’s invasive studies and bothersome to the patient. One of the key points that are pursued in the latest developments is therefore do so promptly and efficiently, Since the factor time is decisive in this type of diseases.
Under this idea, is a project developed jointly by the University of Tokyo and the University of Harvard, which consists in Advanced capable of dual pressure sensor, adapts to the fingers of the hand as if it were a glove, and which will serve to detect tumors at early stages.
The replacement of mammograms
Pressure sensors are not new, there are developments for some years, where his main problem is their lack of efficiency after a dual, What makes them useful only in flat, not curved surfaces that do not work on surfaces in movement.
Now, thanks to this development, could be a breakthrough especially in the detection of breast cancer, where to today it depends on almost in its entirety of mammograms, a painful study and invasive that continues to touch detection. With this new sensor, the idea is to avoid mammograms, since everything would be detected immediately through a study of touch, because sensors can be adapted to the fingers for an exam.
The sensor will be able to identify a normal chest and one with tumors, this just apply a little pressure, since it’s a digital pounding that It measures up to 144 locations at the same time. Its thickness is just eight micrometers (thousandth of a millimeter) and is made with electronic switches, organic transistors made of carbon and oxygen, as well as a pressure sensitive nanofiber structure.
This makes that you can accurate measurement of radii of up to 80 micrometers, overcome the barrier of 100 micrometers having previous sensors. But certainly the element that makes it more attractive is its flexibility, so you can measure different parts of the human body regardless of bending.
Sungwon Lee, leader of the project at the University of Harvard, reviewed:
“We have tested the performance of our sensor in an artificial blood vessel and we have found that it can detect even small changes in pressure and the speed of the pressure spread”.
Unfortunately the limitation in price and availability of their materials, which include leather fluorine and carbon nanotubes and Graphene for driving, does that their production is large-scale almost impossible to today, Therefore, its creators are working on a solution to use another type of material. Meanwhile, they have predicted have a final version for sale sometime in 2019.
