In one embodiment, the method includes joining a first end portion of a braided lead wire to a coiled magnet wire. A dielectric-containing material is applied in a wet-state over the coiled magnet wire and over the first end portion of the braided lead wire. The dielectric-containing material is cured to produce an electrically-insulative body in which the coiled magnet wire and the first end portion of the braided lead wire are at least partially embedded. Prior to application of the dielectric-containing material, the braided lead wire is at least partially impregnated with a masking material deterring wicking of the dielectric-containing material into an intermediate portion of the braided lead wire. In certain cases, the masking material may be removed from the braided lead wire after curing, and the electrically-insulative body may be sealed within a canister.

  • Publication number: 20150109223
    Abstract: A haptic electromagnetic actuator for track pad is provided. The actuator includes an array of electromagnets with alternating South and North poles on a first end, each magnet comprising a metal core and an electrical wire around the metal core. The array of magnets is coupled to a base plate on a second end opposite to the first end. The actuator also includes an attraction plate at a distance from the first end of the array of the magnets such that the attraction plate moves toward the magnets when an electrical current flows through the electrical wire around the metal core and moves away from the magnets when the current becomes zero. The array of magnets is configured to form a uniform gap from the attraction plate.
