The development of a smart pen discovers Parkinson disease by 96% by writing

Researchers have managed to develop a special pen with a magnetic ink, which can monitor early signs and symptoms of Parkinson’s disease, known as Parkinson, through handwriting analysis. The results of this innovation were published in the journal “Nature Chemical Engineering”, and the study indicates the possibility of using the pen as a low -cost and high -precision diagnostic tool, especially in countries with limited medical resources. The new innovation depends on a pen with a magnetic ink, which accurately records the movement of the hand while writing on a surface or even in the air. These movements are converted into electrical signals that are later analyzed by an artificial nerve network; It is a technique that relies on artificial intelligence to simulate the way the brain works to identify complicated patterns. According to the researchers, the pen was able to distinguish between the handwriting of Parkinson patients, and those with an exact rate of more than 96% in an initial experience that included 16 people. Parkinson’s disease is one of the fast -growing degenerative neurological diseases, affecting nearly 10 million people around the world; Its symptoms, such as tremoring, hardening and slow movement, causes a major obstacle to the movement of patients, and affects the quality of their lives greatly. The traditional procedures for the diagnosis of Parkinson, and its monitoring depend on the observation of the kinetic symptoms, which are often inaccurate, and depend on the doctor’s experience, and are not objective and quantitative criteria, and access to the specialized resources to diagnose Parkinson is limited, especially in low -income countries suffering from lack of neurologists. Despite the modern progress of identifying important indicators that appear long before the rise of motor symptoms; Like the examination of the alpha-cyinocaline protein levels or retinal abnormalities, the determination of these indicators is usually advanced equipment and specialized experience, which is often only available in central health care facilities. Therefore, the need remains urgent to diagnose a quantity, low cost, and is available for Parkinson disease in large mass circles. How does the diagnostic pen work? Handwriting is a complicated process in which cognitive, cognitive and microscopic abilities are intertwined, all of which are greatly influenced by Parkinson disease. If the kinetic symptoms affect the dominant hand, the analysis of handwriting patterns can provide decisive visions, and quantitative indicators for diagnosing the disease. Although traditional handwriting analysis instruments such as digital tablets are common, they often focus on the detection of the writing paths and ignore the kinetic symptoms that occur during the writing process itself. Here comes the role of the new diagnostic pen, and the pen is characterized by a flexible magnetic end and ink of the magnetic fluid, and the principle of his work depends on the conversion of writing movements, either on the surface or in the air, in high -resolution and analysis signals. When applying pressure during writing, the flexible end is deformed, leading to a change in the magnetic flow, and this change, in addition to the dynamic movement of the magnetic ink, generates electric tension signals in the surrounding file. The diagnostic pen consists of two main components; A flexible magnetic end and magnetic ink. The flexible end is tightly linked to the upper part of the printed 3D structure, ensuring stable components. The magnetic ink is stored in a replaceable plastic tank and is equipped with a covering to prevent leakage and evaporation. All ingredients are combined in the pen structure, then a connection thread is woven into a file structure that transforms the changes to the magnetic flow into a high -resolution voltage signals for handwriting analysis, and eventually the file is surrounded by a fist of a substance called polyphenin to give a surface resistant. The flexible party is made by the inclusion of magnetic molecules in the silicone matrix, which offers two functions for the pen, the first of which is to bring about a vertical magnetic field to maintain a magnetic in the magnetic ink, and under external mechanical pressure the limb becomes distorted, which changes the direction and divergence of the magnetical molecul Magnetic molecules. This change, in addition to the dynamic movement of the magnetic ink within the diagnostic pen, leads to changes in the pure magnetic flow by the surrounding file, which in turn leads to the generation of an electrical tension according to the Faradai Act for Electromagnetic Urbanization. A low -cost technique to assess the clinical capabilities of this pen, an experimental human study that includes 3 patients with Parkinson and 13 intact participants, and the diagnostic pen that recorded a high -resolution handwriting signals, and the analysis of these signals could have been with the help of a smart neurological network and accuracy of 96.22%. The development of this diagnostic pen represents low -cost technology, widely distributed, reliable and has the ability to improve Parkinson’s diagnosis on large population groups and in limited resources. This pen can provide an innovative path to complete the current Barkinson diagnosis methods by supporting an approach that depends on non -species, which facilitates early detection in wide population circles, as it is especially useful for unparalleled individuals who may not realize that they are in Parkinson, and for those who live in areas, the chemicals are diagnosis. The research team believes that the pen can contribute to the judgment of this gap, especially in environments suffering from a lack of medical cadres or advanced technology, as it can be used for diagnosis in the future, but also to detect the development of the disease in patients over time. The researchers conclude by the need to perform future experiments on a larger scale to confirm the effectiveness of the pen through larger samples of patients, which can open the door to generalize its use worldwide as a smart instrument, and easy to use to detect Parkinson in the early stages.
