In the area of business and personal communication, to draw an example, there are many applications<br />
and opportunities for electronic textiles. Computers, cellular phones, personal data assistants,<br />
beepers, and pagers are common devices used today for mobile communication. Users of these<br />
technologies are carrying around a separate display, battery, keypad, speaker, and ringer for each of<br />
these devices. Electronic textile technologies can potentially integrate these items directly into textile<br />
and apparel products with shared resources. This would eliminate the need to carry such devices and<br />
increase mobility, comfort and convenience. The technologies supporting electronic textile<br />
communication include integrated input and output devices such as computer keypads and display<br />
screens and integrated antennas for mobile phones use, internet connections and downloads.<br />
In the following, examples are discussed that make use of a textile structure to integrate single or<br />
several electronic devices.<br />
Although there are many companies and institutes involved in research projects going on in the field of<br />
wearable electronics, the US military is still a major sponsor, through such agencies as the US Army<br />
Natrick Soldier Center and The Defense Advanced Reseach Projects Agency (DARPA).<br />
A first approach to integrate electronics into textile structure was certainly achieved by gloves wired to<br />
the computer that allows it to take input from a user's hand gestures. Sensors in the glove detect the<br />
wearer's hand movements, and transmit these to the computer in a digital format which the computer<br />
can interpret. The Dataglove is one invention made in the late 1980ties that can be exemplary<br />
named in this case (others are for example the PowerGlove and the Cyberglove ® ). The Dataglove<br />
is a trademark of the company VRLOGIC in Germany. The first prototype consists of a Latex glove to<br />
which tubes equipped with sensors for each finger are attached by stitching. Hence, ten finger joints<br />
could be monitored. Four wires were used for each finger or tube to build up a circuit. The voltages<br />
coming out are varying depending on the finger flex [5, 59].<br />
