Smart Clothing That Actively Heats or Cools Your Body

This patent describes a system for clothing that can actively heat or cool a person by using special electronic modules placed in a frame on the fabric.

What it covers

This apparel thermo-regulatory system actively heats or cools a person wearing it. It includes a piece of clothing, like a jacket or shirt, that has a sturdy frame attached to its outer surface at a specific spot. This frame has openings, and an absorbent material is placed on its exposed side. Inside these openings, there are special electronic parts called thermoelectric modules that can be easily put in or taken out. These modules are what actually generate the heat or cold, allowing the wearer to adjust their body temperature. For example, a hiker could use this system to stay warm in cold weather or cool down during a strenuous climb.

What it doesn't cover

• —Does not cover apparel that heats or cools using only passive methods, like special fabrics or phase-change materials, without active thermoelectric modules.
• —Does not cover systems where the heating/cooling elements are permanently integrated into the fabric rather than being releasably positioned within a frame's aperture.
• —Does not cover apparel where the thermoelectric modules are not housed within a dimensionally stable frame with an absorbent material.
• —Does not cover systems that use resistive heating elements or fluid circulation for temperature regulation instead of thermoelectric modules.
• —Does not cover apparel where the temperature regulation system is affixed to an inner-facing surface of the apparel item.

The clever bit

The novelty lies in the modular design, specifically using a dimensionally stable frame with apertures to releasably hold thermoelectric modules, combined with an absorbent material. This allows for easy insertion, removal, and potential replacement of the active heating/cooling components.

Why it matters

Maintaining a comfortable body temperature is important for health, performance, and energy efficiency. This technology could allow individuals to customize their thermal environment, potentially reducing the need to heat or cool entire buildings. It could be particularly useful for outdoor workers, athletes, or people in extreme climates, offering a personalized approach to thermal comfort.
