Temperature sensor

Printed sensors are more flexible, lighter and cheaper than conventional sensors. They can be integrated directly into products and enable completely new applications, e.g. in smart textiles, e-mobility or medical technology.

Yes, many manufacturers offer customised temperature sensors that are tailored to specific requirements, such as shape, temperature range or material.

Thanks to modern materials and precise printing processes, they deliver high-resolution real-time data and are suitable for many industrial applications. At the same time, they are lighter in weight and require less space.

Additive manufacturing enables printed sensors to be produced on a large scale in a cost- and material-efficient manner. They enable flexible, ultra-thin designs that can be easily integrated into existing product geometries or film composites. Ideal for smart packaging, wearables or IoT applications.

Standard versions are designed for a temperature range of approx. -20 °C to +85 °C. For high-performance applications, systems with extended temperature ranges up to 120 °C are also available. Depending on the substrate and the printing materials used.

The sensors can be integrated into existing electronics via ribbon cable, conductive ink or pressure contact. Evaluation is usually carried out via simple resistance measurement (NTC or PTC behaviour) or via a digital interface during system integration. Combination with RFID/NFC or flexible battery systems is also possible.

A printed temperature sensor uses special materials such as PTCs, which change electrically when the temperature changes. This information is converted into a digital signal via ultra-thin, screen-printed layers.

Printed temperature sensors are temperature-dependent electrical components that are applied to flexible substrates (e.g. PET, PI, paper) using roll-to-roll or flat printing processes. They are typically based on conductive polymers or pastes whose resistance changes depending on temperature.

Depending on the material system used and calibration, printed temperature sensors typically achieve an accuracy of ±1 °C to ±2 °C in the range from -20 °C to +85 °C. For more precise requirements, multi-point calibrations and special evaluation electronics can be used.
