Core Technology

Electrically Heated Clothing / Battery Heated Clothing

The technology centres around a core unique polymer based element that heats up when low voltage is passed through it and is powered by either rechargeable batteries, a mains power adaptor or from the accessory socket of a car or motorcycle. By regulating the voltage applied the heating element can be made to heat up to a pre-defined level to create a uniform area of heat with no hot spots. Uniform distribution and dissipation of heat allows the heating element to be located in close proximity of the area to be heated, thus maximising heating and minimising heating response time.

Loading the polymer, at the heart of the heating component, with conductive particles enhances its conductivity properties and results in the element exhibiting a positive temperature coefficient (PTC) when heated.

PTC is a characteristic many materials exhibit whereby resistance increases with temperature in a non-linear fashion. Once the material reaches the desired temperature, it self regulates. An optional universal controller allows the user to select temperature settings.

How do the heating components work?

When the heating element is at room ambient temperature, numerous conductive "chains" exist within the material. When low voltage is applied, current flows through the device, causing a rise in heat. Once the heat rises, it creates a small expansion, causing the conductive particles to move apart from each other. The resistance of the device increases, the material conducts less current and temperature is regulated.

Key Features

Virtually indestructible. The rubber like structure of the heating element makes it flexible enough to be configured into almost any shape. Thus, making it easy to incorporate into most garments and systems.

Unlike wire based systems, the heating component continues to operate even if slit or torn without the possibility of a short circuit.

Operating from a low voltage means that heating systems for light users can be powered by rechargeable batteries. The weight of these battery packs (no heavier than a modern mobile phone) makes the heating system ideal for portable use.

• Intrinsically safe - due to the positive temperature coefficient properties of the polymer.
• Inert. The polymer is resistant to most chemicals making it ideal for use in extreme environments.
• High energy efficiency - over 98% conversion of electrical energy into heat.
• Competitively priced.
