Cient\u00edficos de la Universidad de California en Los \u00c1ngeles (EE UU) desarrollaron un bol\u00edgrafo con ferrofluido, una tinta con peque\u00f1as part\u00edculas imantadas. Al escribir, la tinta se desplaza y genera\u00a0se\u00f1ales el\u00e9ctricas analizables mediante inteligencia artificial.<\/p>\n

El sistema analiza los movimientos de los pacientes en el aire, o en cualquier superficie, y distingue su\u00a0caligraf\u00eda<\/p>\n

El estudio, publicado en\u00a0Nature Chemical Engineering, indica\u00a0que su funcionamiento podr\u00eda ayudar a detectar el p\u00e1rkinson, ya que integra una red neuronal capaz de identificar patrones en los textos manuscritos de personas con esta enfermedad neurodegenerativa.\u00a0<\/p>\n

Su sistema analiza los movimientos de los pacientes en el aire, o en cualquier superficie, y distingue su caligraf\u00eda para diferenciar con una precisi\u00f3n de m\u00e1s del 95 % si una persona tiene o no p\u00e1rkinson en las fases iniciales de la enfermedad.\u00a0<\/p>\n

<\/a><\/p>\n

Tareas f\u00e1ciles de escritura<\/h2>\n

El investigador principal del estudio, Jun Chen y su equipo reclutaron a 16 personas para su proyecto: 3 pacientes de ellos ten\u00edan p\u00e1rkinson y 13 no, con una distribuci\u00f3n equitativa por sexo.\u00a0<\/p>\n

Los participantes realizaron tareas f\u00e1ciles de escritura como el dibujo de l\u00edneas onduladas para asegurarse de que no hubiera complicaciones para las personas con dificultades de lectura o hablantes no nativos.\u00a0<\/p>\n

Detectaron que, en aquellos con p\u00e1rkinson, surg\u00edan\u00a0picos menores\u00a0asociados a irregularidades motoras<\/p>\n

El bol\u00edgrafo registr\u00f3 se\u00f1ales el\u00e9ctricas gracias al movimiento que los participantes hac\u00edan al escribir y detectaron que, en aquellos con la enfermedad, surg\u00edan picos menores asociados a irregularidades motoras.\u00a0<\/p>\n

Despu\u00e9s, una red neuronal distingui\u00f3 a las personas que ten\u00edan la enfermedad y las que no con una precisi\u00f3n media del 96,22 %.<\/p>\n

<\/a><\/p>\n

Diagn\u00f3stico complementario<\/h2>\n

Tradicionalmente, dado que la mayor\u00eda de los s\u00edntomas diferenciales incluyen temblores en las extremidades, el diagn\u00f3stico tradicional se realizaba mediante la observaci\u00f3n m\u00e9dica de las habilidades del paciente.\u00a0<\/p>\n

Ahora, este nuevo sistema permite saber si una persona tiene la afecci\u00f3n en zonas con menores recursos. Esto se debe a que su fabricaci\u00f3n depende de la\u00a0impresi\u00f3n 3D y se elabora con materiales de bajo coste.<\/p>\n

En zonas de bajos recursos hay muy poco personal sanitario especializado\u00a0<\/p>\n

De hecho, el acceso a personal sanitario especializado en estas regiones es muy bajo, con un n\u00famero insuficiente de neur\u00f3logos (entre 0,003 y 0,3 por cada 100. 000 habitantes). Este hallazgo es especialmente beneficioso para\u00a0personas no tratadas y que todav\u00eda no se reconocen como posibles pacientes, seg\u00fan indica el estudio.\u00a0<\/p>\n

<\/a><\/p>\n

Sin fuentes de energ\u00eda externa<\/h2>\n

Asimismo, al generar electricidad con su punta magnetoel\u00e1stica y la tinta de ferrofluido, este dispositivo no necesita energ\u00eda externa para funcionar.\u00a0<\/p>\n

La raz\u00f3n de este fen\u00f3meno se encuentra en el campo electromagn\u00e9tico. Cuando se presiona su punta o se mueve el ferrofluido de su interior se altera el flujo magn\u00e9tico.<\/p>\n

El dispositivo podr\u00eda complementar los m\u00e9todos existentes para el diagn\u00f3stico del p\u00e1rkinson y facilitar la detecci\u00f3n temprana<\/p>\n

Estos cambios o modificaciones las reciben unas bobinas capaces de inducir tensi\u00f3n el\u00e9ctrica analizable seg\u00fan lo que los cient\u00edficos llaman la ley de inducci\u00f3n de Faraday.\u00a0<\/p>\n

En definitiva, este bol\u00edgrafo podr\u00eda ofrecer una v\u00eda innovadora que complemente los m\u00e9todos existentes para el diagn\u00f3stico del p\u00e1rkinson y facilitar la detecci\u00f3n temprana.<\/p>\n

No obstante, los autores se\u00f1alan que todav\u00eda necesitan m\u00e1s estudios para explotar el\u00a0potencial\u00a0del dispositivo en la progresi\u00f3n del p\u00e1rkinson en sus diferentes etapas.\u00a0<\/p>\n
