**2.5 Communication**

One of the components of smart textiles is the communication component, which is shaped according to the type and need of communication. There are many types of communication within smart textiles. Some of the basic situations in which smart textiles are contacted are as follows: in one element of the garment itself; can be mounted between two different elements of the garment; and in order to command the garment by the wearer, contact is made to inform the wearer or his surroundings. In today's prototypes, communication within the garment is provided by optical fibers or by conductive fine wires. They are naturally woven and can be placed in textiles without the use of stitches. A specific communication protocol is followed to communicate with the wearer. The outlines of this protocol can be provided by the technologies described below. Optical fibers are used in the creation of optical screens, and France Telecom has managed to produce several prototypes by producing a sweater and a backpack. On the other hand, since it requires more than one fiber for a pixel, it appears that the present situation needs further consideration. Another communication protocol in smart textiles is pressure-transmission systems. Information can be provided to the garment with pressure-sensitive textile materials, and a data processing element needs to process these entered orders. In some intelligent textile applications, communication with wider environmental elements is important. For example, there are many situations in which the suit is required to interact with the vehicle when 41 drivers are handled. The first thing that comes to mind in the communication of the dress with the vehicle is the seat in which it is in direct contact. A wireless connection can be achieved by integrating an antenna into the suit. This antenna is integrated into the clothes. The major advantage of this integration of antennas to the garment is that a large area can be used for communication without the user even being aware of it. In the summer of 2002, a prototype was produced in Philips Research Laboratories. With regard to road safety or driving comfort, a lot of data about the driver, such as heat comfort, concentration etc., can be obtained using intelligent textiles for a better and safer driving quality. For risky human profiles, for example, heart patients can anticipate the problems of clothing and provide information to stop the vehicle or even call for help if necessary.

Although these developments are considered unquestionable, it is thought that these studies can only be implemented in the future with more advanced technology due to the limited information that can be obtained from the human body and the lack of materials and concepts for the systems to process this information [8, 9].
