Humidity sensors
What are humidity sensors specifically?
Our printed humidity sensors are innovative, extremely thin sensor components that are manufactured from printed electronics using flexible substrates. Rather than relying on traditional, often bulky sensor technology for our product, we use three-layer screen-printed IDE electrodes. They accurately register air humidity within the range of 15–85% relative humidity, even after prolonged exposure to higher humidity levels, reliably and without any loss of performance.
A practical example: The PrintElectric® humidity sensor, a product from the Witte Technology sensor series, converts moisture and humidity changes into electrical signals, enabling a wide range of modern, intelligent applications.
Advantages of humidity sensors
- Extremely thin and flexible: Can be placed onto a wide variety of surfaces or materials, e.g. flat roofs or wound dressings.
- Cost-effective: More affordable than conventional sensor technology thanks to our innovative printing processes.
- Robust and replicable: High repeatability, even under difficult environmental conditions.
- Easy integration: Compatible with standard connectors such as FPC or crimp with an efficient data transfer.
- Reliable alarm function: An alarm signal will be triggered immediately in the event of a short circuit caused by humidity and moisture. Ideal for your monitoring solutions.
Thanks to these advantages, our printed humidity sensors offer a comfortable alternative to conventional solutions, especially where low height, high sensitivity and cost-effectiveness are required.
Application areas for our printed humidity sensors
Our flexible, printed humidity sensors enable manufacturers to reliably detect moisture and liquids directly in the product, cost-effectively and easily integrated. The sensors are particularly thin, versatile and suitable for disposable products, embedded systems or smart packaging. Thanks to modern printing technology, our individually tailored solutions serve a wide variety of industries.

Technology & competent production
Witte Technology develops and manufactures printed humidity sensors for reliable monitoring of moisture and liquids. The sensors are based on high-resolution screen printing on flexible substrates such as PET, PEN, polyimide or TPU. Both resistive and capacitive moisture sensors are used, as well as leakage sensors that react to a wide variety of liquids. These include water, chemicals and biological solutions.
Thanks to our state-of-the-art roll-to-roll and sheet-to-sheet manufacturing, we can produce even large quantities economically. The sensor architecture is fully customisable, whether in terms of detection sensitivity, fluid type, integration into existing systems or material properties such as chemical resistance and medical compatibility.
Witte Technology offers individual, scalable solutions for manufacturers who want to integrate smart monitoring into their products.
