    Abstract: A programmable metallization device comprises a first electrode and a second electrode, and a dielectric layer, a conductive ion-barrier layer, and an ion-supplying layer in series between the first and second electrodes. In operation, a conductive bridge is formed or destructed in the dielectric layer to represent a data value using bias voltages having the same polarity, enabling the use of diode access devices. To form a conductive bridge, a bias is applied that is high enough to cause ions to penetrate the conductive ion-barrier layer into the dielectric layer, which then form filaments or bridges. To destruct the conductive bridge, a bias of the same polarity is applied that causes current to flow through the structure, while ion flow is blocked by the conductive ion-barrier layer. As a result of Joule heating, any bridge in the dielectric layer disintegrates.

    Abstract: A tactile display writer unit includes a probe having a contact tip, and at least a first actuator and a second actuator coupled to the probe, whereby activation of the actuators results in a displacement of the probe tip in one or more of a z-direction and in a lateral direction having a vector in an x-y plane. Also, a display writer includes a plurality of such units supported in an x-y array. The writer units may have a third actuator coupled to the probe. Also, a tactile vision system includes such a display writer, an image processor, and an image sensor. The processor transforms RGB image information from the image sensor into hue-based information having two or more attributes; and the actuators in the tactile display writer are activated by the information attributes. Also, a method for producing a tactile color stimulus at a site on the skin of a subject includes providing a probe having a contact tip; displacing the tip at the contact site in a direction generally normal to the skin surface at the site to an extent that relates one attribute of a hue-based model of the color, and displacing the tip in at least one lateral direction generally in a plane parallel to the skin surface at the site to an extent that relates to at least one additional attribute of the color.

    Abstract: A programmable metallization device, comprises a first electrode; a memory layer electrically coupled to the first electrode and adapted for electrolytic formation and destruction of a conducting bridge therethrough; an ion-supplying layer containing a source of ions of a first metal element capable of diffusion into and out of the memory layer; a conductive ion buffer layer between the ion-supplying layer and the memory layer, and which allows diffusion therethrough of said ions; and a second electrode electrically coupled to the ion-supplying layer. Circuitry is coupled to the device to apply bias voltages to the first and second electrodes to induce creation and destruction of conducting bridges including the first metal element in the memory layer. The ion buffer layer can improve retention of the conducting bridge by reducing the likelihood that the first metallic element will be absorbed into the ion supplying layer.
