The insertion of thread-like sensors changing their properties reproducibly upon varying environmental conditions is one favoured means of equipping textiles in the vehicle interior with sensory capabilities. In this way, for example, the tensile load and the compressive force which are exerted on textiles can be easily supervised using sensor fibres which alter their electrical resistance when they are stretched or pressed, respectively. In applying such sensors, existing as well as newly developed textiles can be equipped with additional functionality besides traditional fields of application in the vehicle interior.
The following developments and applications are discussed:

- Textile sensors for the detection of applied load and environmental conditions
- Textile integrated transfer of energy and data
- Textile switching and indicator elements
- Textiles for vehicle occupant monitoring

Highly conductive textile yarns which were developed by TITV and which are established under the trade mark ELITEX are the basis for many recent R&D efforts such as textile circuit boards as well as textile electrodes for the detection of bioelectric signals. Furthermore the opportunities and constraints of textile sensors are discussed in the light of applications in the micro systems technology.
Weight reduction, flexibility and air permeability of textiles, highly effective textile manufacturing and subsequent processing of functionalised textiles “off the role”, assembling advantages in the overall system of the vehicle interior, and individual options of structuring due to less limitation of design are pointed out as the most important advantages.
