FlexiSens focuses on the development and application of flexible and printable magnetic field sensors based on the Hall effect and magnetoresistive effects. These novel high performance magnetic field sensors developed on ultra-thin flexible substrates have high mechanical adaptability. Flexible and printed sensors can be applied not only to various flat but also curved objects due to their extremely thin and unconventional mechanical properties.

Magnetic field sensors detect, measure and control any kind of movement: Translation, rotation, vibration, distancing. They are fast, durable and very reliable. Conventionally, sensors are rigid. Our technology allows the design and manufacture of flexible and printed sensors. Moreover, the sensitivity to the magnetic fields can be adjusted individually. With our technology, various flexible substrates such as ultra-thin polymer films and conventional flexible printed circuit boards can be functionally equipped as magnetic field sensors.

Our flexible sensors are located on polymer substrates with thicknesses from 1 µm to 100 µm. They can be processed on a sample area of up to 12" wafer size. The sensor layout can be fully configured for the specific application. In addition, the sensors are mechanically bendable to below 1 mm bend radii with stable electrical properties despite mechanical deformations. The sensors are individually adjustable with respect to their sensitivity to magnetic fields in the range of 1 micro Tesla (µT) to 200 mT and operate in the temperature range of -40 to 165 °C relevant for the automotive industry.
