Heating and cooling jacket

The jacket incorporates an electro-conductive fabric, called Gorix E-CT as heating system, which
heats the wearer but reacts to body heat to maintain a desired temperature without overheating [105].
Lately, at the “1 st International Scientific Conference on Intelligent Ambience and Well-Being” in 2005
researchers of the Wearable Computing Laboratory at the ETH Zürich presented a smart fabric
system with temperature sensing and signal transmission capability. The woven hybrid fabric consists
of PET yarn and copper wires which are known for their high thermal conductivity. Thus, the fabric
itself represents an array of temperature sensors which are capable to measure the temperature
profile of a surface, e.g. a human body. This textile structure might be used for instance to monitor the
temperature to which fire fighters are exposed during their mission. Beyond that, the fabric can not
only be integrated into clothing, but also in car seats for instance.
The warmX ® -undershirt is constructed by a jersey knit with integrated silvered fibres in the kidney
zone. The silver-coated polyamide fibres warm up directly on the skin, power is supplied by a small
battery positioned in a small waist pocket at the front of the shirt. The power controller is connected to
the conductive fabric through two snap fasteners. Thus, the power controller and the conductive fabric
form an electric circuit around the waist.
