substrate including at least one electrical conductor that provides an electrical contact to the electronic<br />

In US patent 2004/0092186 a textile electronic connection system is claimed. The system comprises a<br />
textile ribbon with integrated transmission lines running lengthwise in the ribbon. A fastener is used to<br />
connect ribbons and thus the transmission lines to each other and to allow a quick connection and<br />
disconnection.<br />
The University of Manchester Institute of Science and Technology in Manchester, U.K., developed a<br />
knitted transducer for monitoring vital signs of the wearer. The knitted resistive strain gauge comprises<br />
a single knitted layer of a conductive electromeric yarn and a non-conductive elastomeric base yarn.<br />
The non-conductive yarn is used for the base knitted structure in which the conductive yarn is laid in<br />
course direction in a predefined e.g. rectangular shape. An increase in resistance will occur due to<br />
stretching of the conductive yarn. The transduction zone is connected to the transducer device by<br />
using conductive fibres in the first and last courses of the transduction zone (patent WO 2004100784).<br />
Philip Leonard patented a textile thread with incorporated electronic elements in US patent<br />
2004/0115430. The threads can be processed into a textile assembly so that the threads can form an<br />
intercommunicating system used for instance in computer, transmitter and receiver, and radio<br />
systems.<br />
A Finnish consortium patented a sensor to be placed on the skin that can be integrated in a garment<br />
and has a contact layer in contact with the skin containing conductive fibres for receiving signals (US<br />
patent 2004/0138546).<br />
Philips patented a wearable body-fat sensor under US 6718200. The sensor is made of a fabric<br />
having an electrode and sensors. They developed for instance a pair of shoes with a weightmeasuring<br />
sensor, a conductive textile and an impedance measuring circuit. The electronic<br />
components are coupled so that the body-fat composition of a person can be measured based on the<br />
data received from the weight sensor and the impedance measuring circuit.<br />
2.1.5 Applications in the interior textile sector<br />
There is also a lot of interest in integrating electronics with interior textiles. Although there are no<br />
examples or products on the market by now, there are many activities going on in the research stage,<br />
