This semi-electronic material based on carbon nanotubes may form a thin glove that can accurately measure the pressure variations

The scientific world has known for years already that a structure of this type can theoretically be an excellent deformation sensor or pressure that increases the reliability of data with minimal calculations and electronics.

“Sensitive fingers of an experienced physician can detect a small tumor but what they feel can not be measured” and translated into digital data that can then be shared, told AFP Takao Someya Professor the University of Tokyo.

This system would also overcome the lack of experience or proper training on palpation of many doctors.

“In the future we might as well save and make some tangible sensations that can only be felt by an experienced practitioner,” the Professor Someya.

The square prototype of 4.8 cm set of side assesses the pressure by 144 points simultaneously.

“conventional pressure sensors are flexible enough to embrace surfaces such as human skin, but they can not accurately measure pressure changes when they are twisted and wrinkled, which makes them unusable on complex surfaces and shifting shape, “said in a statement the team Takao Someya and teachers Sungwon Lee of the University of Tokyo Zhigang Suo associated with the University Harvard.

“We tested the performance of our sensor with an artificial blood vessel and have thus verified that could measure small changes in pressure,” said the team whose work is detailed in an article to be published Tuesday on the website of the British journal Nature Nanotechnology.

This synthetic membrane is originally transparent but once assembled with the transistors, organic switches and circuits, the whole looks like a gold metal sheet, whose thickness is from 3.4 to 8 micrometers (millionths of a meter).

The product should become even more durability before it could be used in medical settings, however, have recognized researchers.

The healing of cancer is strongly dependent on the stage at which they are detected: the more they are, the sooner the prognosis is good, but the cost and the constraint posed some early screening discourage many patients pay them regularly in 2013. A Japanese university laboratory had presented a prototype device able to detect it as an abnormality in the breast blood flow as a possible sign of cancer.

The object was in the shape of a ball integrating a sensor emitting diode (LED) and a phototransistor to detect any accumulation of possibly related to a cancerous tumor blood, had explained to AFP Professor Mineyuki Haruta.
