A lawn mower or stand-on powered drivable machine has an electrical port that receives current from an alternator powered by the engine or motor. The port receives a plug from a garment worn by the lawn mower operator. The garment includes one or more thermo-electric elements that are powered from current extending through the port. The thermo-electric (TEC) elements may be resistive heaters to warm the operator or TEC coolers to cool the operator. Furthermore, the garment may include a rechargeable battery that powers the thermo-electric elements when the plug is disconnected from the port.

A multifunctional smart garment textile is disclosed herein. It comprises plural conductive yarns, wherein each of the plural conductive yarns includes cotton threads, multiwalled carbon nanotubes and iodine-modified polypyrrole, and wherein the cotton threads, the multiwalled carbon nanotubes and the iodine-modified polypyrrole are interwoven with each other in a weight ratio ranging from 1:1:1 to 3:1:1.

A battery powered heating pad for the breast for lactating women. The battery powered heating pad for the breast generally includes a battery powered (or electrically-powered) heating pad for the breast. The heating pad includes a U-shaped body sized and shaped to be removably positioned within a pocket in a heating pad holder for attachment to a maternity bra. The heating pad also includes a U-shaped heating element positioned in alignment with the U-shaped body to provide heat at the outer surface of the U-shaped body. A power unit is also adapted to fit within the body, and is electrically connected to the heating element to provide electrical power to it. An open portion of the U-shaped body allows access to a woman's nipple without removing the electrically-powered heating pad.

A heating element composite comprises a substrate of one or more fibers or threads and an electrically-conductive polymer coating comprising an electrically-conductive polymer material deposited onto the one or more fibers or threads. A thickness of the electrically-conductive polymer coating is at least about 100 nanometers and the electrically-conductive polymer coating covers at least about 75% of an external surface area of the one or more fibers or threads of the substrate. The resulting heating element composite has a sheet resistance of from about 2 Ω/□ to about 200 Ω/□.

A garment structure having an adjustment mechanism for abutting at least one pad unit against a human body includes a garment body, at least one adjustment belt, and at least one pad unit being an electrode pad unit, a heating pad unit, or an electrode pad unit with a heating unit. The adjustment belt has one end connected to the garment body, and another end fixed to an outer surface of the garment body. When the adjustment belt is pulled tight, the garment body is dragged to move toward the skin. The pad unit is disposed on the garment body, and moves, along with a portion of the garment body being dragged, to abut against the skin. A user wearing the garment structure can pull and secure the adjustment belt to enable the pad unit to easily and quickly abut against the skin to proceed with electrotherapy and/or heat therapy.

A polymer thick film carbon black composition comprising 6-13 wt % conductive carbon black powder; and 87-94 wt % organic medium comprising thermoplastic polyurethane resin dissolved in an organic solvent may be used to form the resistive element of heaters in applications where significant stretching is required, particularly on substrates that can be highly elongated and, in particular, that can be used in wearable garment applications.

A heated article of clothing including a garment body, a heater coupled to the garment body, a heater supply cable configured to provide electrical power to the heater, and a battery pack configured to power to the heater by way of the heater supply cable. The garment body includes a first compartment configured to hold the battery pack, a second compartment configured to alternatively hold the battery pack, and a pass-through connecting the first compartment to the second compartment internally within the garment body such that the battery pack is movable between the first and second compartments while remaining coupled with the heater supply cable.

A heating pad, a portable electric heater and/or an article of manufacture. The heating pad comprising: a first heating fabric comprising graphene; a nanotube-based film having a first surface coupled to the first heating fabric; a second heating fabric coupled to a second opposing surface of the nanotube-based film; and a flexible circuit disposed between the first heating fabric and the nanotube-based film, the flexible circuit configured to facilitate an increase in temperature by at least the first and second heating fabrics.

A lawn mower has an electrical port that receives current from an alternator powered by the lawn mower engine. The current and voltage sent the electrical port depend on a flywheel and stator arrangement operatively connected to the alternator. The stator may be replaceable or interchangeable to selectively determine the alternator current and voltage output. The port receives a plug from a garment worn by the lawn mower operator. The garment includes one or more thermo-electric elements that are powered from current extending through the port. The thermo-electric elements may be resistive heaters to warm the operator or TEC coolers to cool the operator. Furthermore, the garment may include a rechargeable battery that powers the thermo-electric elements when the plug is disconnected from the port.
