Fraunhofer IPMS has achieved a significant breakthrough in materials research. With the newly developed chips based on interdigital electrodes, sensitive and innovative materials can be analyzed much more efficiently. These include materials for organic light-emitting diodes (OLEDs), organic solar cells, organic field-effect transistors (OFETs) and metal oxide-based gas sensors. This significantly simplifies the testing process, shortens development times and represents a decisive step forward for the development of next-generation electronic technologies.
In order to adapt this performance to different applications, Fraunhofer IPMS has worked closely with partners and clients in recent years. Project manager Henry Niemann explains: “The chips have been continuously developed further, for example through new electrode geometries, different electrode materials and adjustments to the gate oxide material and thickness.” Until now, the simple and parallel contacting of several electrodes has been a particular challenge. With the new measuring adapter, Fraunhofer IPMS has now succeeded in closing this gap. The measuring adapter enables the parallel contacting of several pairs of interdigital electrodes and significantly increases the efficiency and quality of the test process.
Group leader Alexander Graf adds: “Our tailor-made chips enable materials researchers to precisely measure and specifically optimize key parameters such as conductivity, field effect, contact resistance and charge carrier mobility.” They thus create the basis for the development, optimization and reproducibility of materials and processes for tailor-made solutions that meet the specific requirements of industry.
A selection of the interdigital electrode chips and the new measurement adapter will be presented at Analytica 2026 at the Fraunhofer stand A3 – #312. There, interested visitors will gain insights into specific application possibilities. Individual appointments can be arranged in advance via the website of the Fraunhofer Institute for Photonic Microsystems IPMS.
