Se estira... se enrolla... se pone blanda o dura... ¿que es? La nueva patente de Sony... se llama "electrorheological fluid device and an electronic apparatus" que vete a saber como se utiliza (si es que lo llegan a utilizar)
Os pongo una "explicación" en el idioma de Chuck Norris:
"The electrorheological fluid device can be applied to, for example, part of a controller of a home-use game machine as another example of the electronic apparatus of the present invention. A user touches a control section of the controller by fingers, and the feeling of touch is controlled by the electrorheological fluid device. For example, if a game player is defeated in a fighting game, the electrorheological fluid device is controlled to become soft in order to improve the realistic sensations in the game
