They create a type of wear that helps to diagnose cystic fibrosis

A description of this device, a type of piece or cloth that adds to the skin in the journal Microsystems & Nanoengineering is published and, according to its authors, will allow to detect a chronic "much earlier" disease and, in Generally, an increasing number that usually starts during childhood.

The experiments to verify the authenticity of this piece, where researchers from the Spanish National Research Council (CSIC) have been working for two years, have done in the laboratory with artificial sweatings; Systhetic fibrosis is usually confirmed during a sweat test, which, among patients suffering from this disease, is more arrow than usual.

The next step will be to start a clinical study at St Joan de Déu Hospital in Barcelona.

This disease, according to data from the Spanish Synthetic Fibrosis Federation, has characterized by affecting the areas of the body that produces secretions and infections and inflammations that it causes in areas of lungs, liver, pancreas and the reproductive system.

There is no cure, but there are treatments to mitigate some of its effects, which is why one of the challenges is to get an early diagnosis that "improves the quality of life of patients and maximizes chances from stretching, "said Neus Sabaté at Efe. Research Institute and Advanced Studies in Catalan and the main project researcher.

The new device, which was a village and which could be below 10 euros (just over 11), could include a skin, battery and sensor park at the same time, which can generate more power or lower the capacity of the fluid it is wet.

When it comes in contact with a liquid (sweat), this type of wearing activates the electrochemical reaction of the two electrodes set in the paper: if the fluid Analyzed more conductor (more arrow, that is, more chloride), the device generates more power, and if it is less driver (less arrow or less chloride), it's less production.

The device is not a direct diagnostic device, but one screening, that is, what it does offers "alarm level".

If this warning signal is given – rather than a higher salinity capacity, the result would have to be confirmed in a hospital unit of cystic fibrosis; The future challenge, which the researcher states, is that this piece could be in hospitals.

And that's what Sabaté explains, in many cases in the children whose symptoms are confused and until they are diagnosed through different hospital units, such as lungs .

Therefore, this piece, if it can be used daily in hospitals, will ignore this disease as soon as possible or in its case to perform a test that is confirmed (on this At present there is a test that stimulates the patient's sweat, which then collects and from which chloride levels are measured).

Juan Pablo Esquivel, another of the authors of this work, explains that, in a CSIC note, this piece does not depend on any external power source, so it would be very easy to use and would & # 39 ; n very low cost.

The team is already exploring the feasibility of this device for other applications such as sweat analysis in athletes or in groups such as firefighters to detect dehydration, and to measure the level of intensity of the irrigation water.

The device, which can also be used in adults, won the award for the best 2018 prototype of the Organic and Printed Electronics Association, which brings together 200 members of Europe, Asia, America , Africa and Oceania.
