    Abstract: A thin sub-layer (<15 ?) of an impurity is formed under, over, or inside a thicker layer (˜30-100 ?) of a high-k (k>12) host material. The sub-layer may be formed by atomic layer deposition (ALD). The layer and sub-layer are annealed to form a composite dielectric layer. The host material crystallizes, but the crystalline lattice and grain boundaries are disrupted near the impurity sub-layer, impeding the migration of electrons. The impurity may be a material with a lower dielectric constant than the high-k material, added in such a small relative amount that the composite dielectric is still high-k. Metal-insulator-metal capacitors may be fabricated by forming the composite dielectric layer between two electrodes.

    Abstract: Systems, articles, and methods for improved capacitive electromyography (“EMG”) sensors are described. The improved capacitive EMG sensors include one or more sensor electrode(s) that is/are coated with a protective barrier formed of a material that has a relative permittivity ?r of about 10 or more. The protective barrier shields the sensor electrode(s) from moisture, sweat, skin oils, etc. while advantageously contributing to a large capacitance between the sensor electrode(s) and the user's body. In this way, the improved capacitive EMG sensors provide enhanced robustness against variations in skin and/or environmental conditions. Such improved capacitive EMG sensors are particularly well-suited for use in wearable EMG devices that may be worn by a user for an extended period of time and/or under a variety of skin and/or environmental conditions. A wearable EMG device that provides a component of a human-electronics interface and incorporates such improved capacitive EMG sensors is described.

  • Publication number: 20140362494
    Abstract: The present invention provides a resin composition comprising: 1 to 20 parts by weight of a reinforcing fiber; 0.2 to 5 parts by weight of an anti-settling agent; 20 to 40 parts by weight of an epoxy resin; 0.1 to 3 parts by weight of a curing agent; and 50 to 75 parts by weight of a high dielectric constant filler. The present invention further provides a dielectric layer produced from the resin composition and a capacitor comprising the dielectric layer. In the dielectric layer made from the resin composition provided by the present invention, the fibers can be evenly dispersed and can enhance the mechanical strength of the resin composition, and cooperate with the epoxy resin to bring excellent toughness. Therefore, the mechanical strength of the produced dielectric layer can be remarkably improved, and its fragility can be effectively overcome when the dielectric layer is used in the PCB double-side etching process.

  • Publication number: 20140362493
    Abstract: New polymeric dielectric materials are provided for high power capacitors, especially for mobile and weapons applications. These materials utilize aminoplast crosslinking in their polymeric structure. The aminoplast crosslinking ability of these materials allows them to be customized for a number of applications, but also allows the materials to have a higher crosslinking density, leading to higher dielectric constants, higher breakdown voltage, and higher thermal stability. These materials can be incorporated into current capacitor manufacturing schemes with little to no processing changes.
