The present invention provides flexible polymer diodes in the form of a printable polymer sandwich configuration similar to that found in electroactive polymer transducers. The inventive flexible polymer diodes comprise a dielectric layer sandwiched between a pair of electrodes. With appropriate optional additives introduced in the electrode formulation and the proper electrical properties in the electrode, a device may be constructed which allows current to pass through for only one polarity of applied voltage.

Polymer diode

A method for fabricating electroactive polymer transducers, the includes providing an electroactive polymer film comprising an elastomeric dielectric polymer, forming an array of electrodes on the film, and sandwiching the electrode array between a top and bottom array of frame components to form an array of electroactive polymer transducers.

Method of manufacturing electroactive polymer transducers for sensory feedback applications

Electroactive polymer transducers for sensory feedback applications are disclosed.

Electroactive polymer transducers for sensory feedback applications

An optical information storage system using optical storage media including multiple data layers or stacks wherein each of the multiple data stacks has a storage density comparable to a conventional single layer optical disk. The optical data storage system comprises an optical medium having a single dedicated servo layer and multiple data stacks which each contain an embedded servo format, a servo laser beam positioned to maintain a first focus point on the dedicated servo reference layer, a read-write laser beam positioned to maintain a second focus point on one of the data stacks, a first, dedicated servo system which provides focus and tracking error correction according to error signals generated from the dedicated servo layer, and a second, embedded servo system which provides focus and tracking error correction according to error signals generated from the data stacks. The dedicated servo layer, in different embodiments of the invention, may be positioned either below or above the data stacks in the optical medium, or interposed between data stacks. The data stacks may comprise discrete physical data layers or &ldquo;virtual&rdquo; data layers defined by a format hologram. The servo and read-write lasers may differ in wavelength and/or polarization.
