A microelectrode array comprises three or more flexible oblong, electrically co-operating microelectrodes in wire and/or ribbon form disposed substantially in parallel. The microelectrodes are electrically insulated except for at a distal section thereof. The array further comprises electrically non-conducting microfibres connecting central portions of the microelectrodes in oblique directions in respect of the array axis. In a preferred array variety the microelectrodes are joined by a glue that is dissolvable or degradable in aqueous body fluid. Also disclosed is a combination of two or more arrays of the invention.

Filter media, triboelectrically charged fibers thereof, and methods for the same are discussed. The filter media may include a first plurality of fibers and/or a second plurality of fibers. The first plurality of fibers may be triboelectrically charged by the second plurality of fibers. The first plurality of fibers and the second plurality of fibers may include polylactic acid fibers and acrylic acid fibers, respectively. The first plurality of fibers and the second plurality of fibers may also include acrylic fibers and polypropylene fibers, respectively. The filter media may include one or more charge additives. A method for preparing the filter media may include contacting the first plurality of fibers with the second plurality of fibers, where contacting the first and second plurality of fibers with one another triboelectrically charges the first plurality of fibers.

An insulating fill material composition for use in outerwear, sleeping bags, bedding, and the like includes 40.0 to 85.0 wt % alpaca fibers, 10.0 to 20.0 wt % bicomponent fibers, and 5.0 to 40.0 wt % polyester fibers. The alpaca fibers have a length of 40.0 to 70.0 mm. The bicomponent fibers have a length of 40.0 mm to 60.0 mm and a linear mass density of 0.11 to 0.33 mg/m. The polyester fibers have a length of 40.0 mm to 60.0 mm and a linear mass density of 0.22 to 0.44 mg/m. Blending, combing, carding, and lapping of the alpaca fibers, the bicomponent fibers, and the polyester fibers forms a matte, which when needled and heated forms a batting having a weight of 50.0 to 400.0 g/m.sup.2.
