temperaturempfindlicher

Temperaturempfindlicher is a term used to describe substances, devices or systems whose properties change with temperature. In practice, it covers a broad range of sensors, materials and components whose output depends on temperature, making them useful for sensing, control, and indication. The English analogue is temperature-sensitive.

Mechanisms vary: electrical resistance can change with temperature in thermistors (NTC and PTC); optical properties may shift with temperature in thermochromic materials or liquid crystals; phase transitions or thermal expansion can alter dimensions, stiffness, or capacitance; chemical reaction rates and diffusion often depend on temperature and influence sensor output.

Examples include thermistors used for precise temperature sensing and compensation; thermochromic pigments and coatings that change color with heat; thermoresponsive polymers that swell or shrink with temperature; liquid crystal temperature indicators; and temperature-dependent electronic devices such as diodes and transistors whose characteristics vary with temperature.

Applications span consumer electronics, automotive, medical devices, environmental monitoring, and packaging. Design considerations for temperaturempfindlicher components include calibration and drift, hysteresis, response time, self-heating, and stability under environmental conditions (humidity, radiation, aging).
