Un equipo de cient\u00edficos ha utilizado esta\ncaracter\u00edstica para crear unas lentillas que detectan las se\u00f1ales asociadas con\nciertos movimientos y cambian la distancia focal. Esto permite usuario acercar\ny alejar la imagen usando simples movimientos oculares.<\/p>\n\n\n\n<p>Los autores del estudio,&nbsp;<a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adfm.201903762\" target=\"_blank\" rel=\"noreferrer noopener\">publicado en Advanced Functional Materials<\/a>, y\nliderados por<a href=\"https:\/\/caigroup.eng.ucsd.edu\/\" target=\"_blank\" rel=\"noreferrer noopener\">Shengqiang Cai<\/a>,\nmidieron las se\u00f1ales electrooculogr\u00e1ficas creadas por los movimientos oculares\n(mirar hacia arriba, abajo, izquierda, derecha, parpadeo, doble parpadeo) y\nluego hicieron una lentilla que respond\u00eda a esos movimientos.<\/p>\n\n\n\n<p>As\u00ed, al activarse por un parpadeo doble, la lente cambia de un\nmodo de visi\u00f3n cercana a un modo de visi\u00f3n a distancia. Dentro de cada modo, la\nlente puede moverse siguiendo la direcci\u00f3n de los movimientos oculares. El\nprincipio de funcionamiento es \u201csencillo\u201d: un conjunto de electrodos se\nextienden a trav\u00e9s de las lentillas y act\u00faan como m\u00fasculos. La lentilla est\u00e1\ncompuesta de capas de pol\u00edmero electroactivo dise\u00f1adas para expandirse cuando\nreciben una se\u00f1al el\u00e9ctrica del ojo.<\/p>\n\n\n\n<p>Los cient\u00edficos esperaban que esto ayudara en pr\u00f3tesis visuales, lentes ajustables y rob\u00f3tica remota.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Fuente: quo.es <\/p>\n","protected":false},"excerpt":{"rendered":"<p>El globo ocular tiene un potencial el\u00e9ctrico constante, incluso cuando nuestros ojos est\u00e1n cerrados o nos hallamos en total oscuridad.
