    Abstract: A three dimensional electrical component (11) having a first side (15) and a second side (16) formed from an electrically insulating polymer matrix capable of heat conversion to an electrically conducting polymer matrix has at least one passageway (17) from the first side (15) to the second side (16) having a tapered wall slope configuration from the first side to the second side with constantly changing cross section of the passageway (17) from the first side (15) through the passageway (17) to the second side (16), an electrically conducting path (18) between the first side (15) and the second side (16) formed by the in situ heat conversion of the walls of the passageway (17) in the electrically insulating polymer matrix. In a preferred embodiment the electrically conducting path is formed by directing a laser beam to the walls of the passageway (17) to heat the insulating polymer matrix to a temperature sufficient to convert it to an electrically conducting polymer matrix.

    Abstract: An electrical component is made from an electrically insulating polymer matrix (27) filled with electrically insulating fibrous filler (34) which is capable of heat conversion to electrically conducting fibrous filler (32) and has at least one continuous electrically-conductive path formed in the matrix by the in situ heat conversion of the electrically insulating fibrous filler. In a preferred embodiment, the fibrous filler is thermally stabilized polyacrylonitrile fibers, and the conductive path is formed by in situ heat-converted thermally-stabilized polyacrylonitrile fibers which have been converted by directing a laser beam through a mask having a predetermined pattern to melt the polymer and to convert the thermally-stabilized polyacrylonitrile fibers into their conductive form.

    Abstract: A microbial fuel cell includes a cell housing (12) having first and second chambers (14,16). The first chamber (14) is adapted for containing a fluid including a biomas. The second chamber (16) is adapted for containing an oxygenated fluid. A cathode (22) extends into the cell housing second chamber (16) and an anode segment of an electrode assembly extends into the cell housing first chamber. The electrode assembly has multiple, substantially aligned, fibers. The outer surfaces of the fibers of the anode segment are adapted for receiving a biofilm.

    Abstract: An electrical component which has at least one end for electrically contacting another component. The electrical component includes a support with a plurality of electrically conductive fibers having at least a portion thereof extending outwardly therefrom to form a brush-like structure. The free end of the brush is adapted to contact the other component. A laser beam cold cuts the free end to minimize heating of the fibers being cut. A brush of this type may be used as a commutator brush in a scavengeless development system of an electrophotographic printing machine.
