FlexiSens

State-of-the-art developments and applications such as electromobility and the “Internet of Things” – which address not only technical but also ecological aspects – are inconceivable without sensors.

We succeeded in developing a worldwide unique, printable and ultra-thin magnetic field sensor without an angle dependency, whereby a multitude of new areas of application can be opened up.

The core of the innovative technology is the nm-precise deposition of metallic multilayers in combination with printing technologies. This makes possible creating a new types of sensors.

Technology

The Helmholtz Innovation Lab “FlexiSens” focuses on the development and application of a flexible and printable magnetic field sensors (Hall effect and magneto-resistive effects). We have developed novel high-performance magnetic field sensors on ultra-thin flexible substrates that have a high mechanical adaptability. Due to their extremely thin and unconventional mechanical properties, flexible and printed sensors can be used not only on various flat, but also curved objects. Our technology enables new fields of application of magnetic field sensors and the realization of printed magnetic field sensors.
