Disclosed embodiments describe approaches for warming a portion of a human body. The warming is based on heated apparel (e.g., a heated glove) coupled to an electrical power supply through a heater controller. The heated apparel (e.g., a glove) can be fabricated using a narrow knit electronic textile. A heater can be constructed from the narrow knit electronic textile. The heater is coupled to the heated apparel (e.g., a glove) for warming a portion (e.g., a hand) of a human body, wherein heating by the heater is accomplished using electrical power from the electrical power supply. The heater is controlled by a heater controller which is interposed between the heater and the electrical power supply.

The garment further includes a first back panel secured to at least a portion of the first edge of the front body panel and a second back panel secured to at least a portion of the second edge of the front body panel.

An article comprising a heater that comprises a high-resistance magnification (HRM) PTC ink deposited on a flexible substrate to form one or more resistors. The HRM PTC ink has a resistance magnification of at least 20 in a temperature range of at least 20 degrees Celsius above a switching temperature of the ink, the resistance magnification being defined as a ratio between a resistance of the double-resin ink at a temperature ‘T’ and a resistance of the double-resin ink at 25 degrees Celsius.

A thermoelectric device including a panel, formed of a thermally insulating material, and having a plurality of thermoelectric elements including compacted conductors inside the insulating material and expanded conductors outside the insulating material wherein the thermoelectric elements run substantially parallel to or at an acute angle relative to the long dimension of the panel. The thermoelectric device may be integrated into a variety of surfaces or enclosures needing heating or cooling with controls and configurations to optimize the application.

An electric-heating assembly adapted to be attached to an article of clothing including: a power supply module, a heating module, and an electric-conductive module. The electric-conductive module is electrically connected between the power supply module and heating module for transmitting electricity from the power supply module to the heating module. The electric-conductive module defining a first inlet terminal and a first outlet terminal is formed by fixing at least one pair of conductive wires on an elastic strip in a stretchable manner, and the conductive wires of the same pair respectively allowing electricity to flow in and out to form a closed circuit with other electrical elements are arranged together to be attached to the elastic strip simultaneously and extend in the same pattern. The electric-heating assembly is controlled by an operable controller to turn on or off.

A glove for heating a hand comprises an upper section and a lower section wherein the upper section comprises in order a first outer protective layer comprising a first fabric or first leather skin, a heating pad, a second fabric, a temperature measuring device located on the inner surface of the second fabric, an electronic module located on the outer surface of the outer protective layer, wherein the heating pad comprises a fabric of staple fibers of pre-oxidized polyacrylonitrile and p-aramid and at least one conductive wire extending from the electronic module over at least part of the outer surface of the heating pad, the conductive wire being held in place on the inner surface of the heating pad by a fixing means. and the lower section comprises a second outer protective layer comprising a third fabric of continuous filament or staple fibers or a second leather skin.

A heating device for heating clothing and a heating clothing include a controller, wires, wire carriers, and heating sheets. Each of the wires is electrically connected to the controller and corresponding heating sheets. The controller is configured to control the heating device. at least a part of the wires are arranged on the wire carriers. the part of the wires arranged on the wire carriers are in a bent shape. When the wires are pulled, the part of the wires on the wire carriers that are in a bent shape provide extra stretched length to avoid pulling on connection between the wires, the controller, and the heating sheets. Meanwhile, the wire carriers share pulling force and reduce pulling on the wires. Thus, the wires are not easily pulled, and a problem of poor electrical connection is avoided.
