The Fraunhofer Institute for Photonic Microsystems IPMS has developed innovative chips that are revolutionizing the characterization of organic materials and accelerating the development of new electronic applications. A newly developed measuring adapter allows for the first time simultaneous contact with up to eight interdigital electrode pairs, setting new standards in precise material analysis. In the context of the growing demand for flexible and efficient technologies, these high-precision measurement methods will be instrumental in improving the performance of future electronic systems.
Fraunhofer IPMS has made a significant breakthrough in materials research. The newly developed chips, which use interdigital electrodes, enable sensitive and innovative materials to be analyzed much more efficiently. These materials include those used in organic light-emitting diodes (OLEDs), organic solar cells, organic field-effect transistors (OFETs), and metal oxide-based gas sensors. This greatly simplifies the testing process, shortens development times, and represents a significant advancement in next-generation electronic technology development.
To tailor this performance to different applications, Fraunhofer IPMS has collaborated closely with partners and clients over the past few years. Project manager Henry Niemann explains, "We have continuously refined the chips, for example, by introducing new electrode geometries and materials and making adjustments to the gate oxide material and thickness." Until now, the simple and parallel contacting of multiple electrodes has been a particular challenge. However, with the new measurement adapter, Fraunhofer IPMS has succeeded in closing this gap. The adapter enables the parallel contact of multiple interdigital electrode pairs, significantly increasing the efficiency and quality of the testing process.
Group leader Alexander Graf adds: "Our customized chips allow materials researchers to accurately measure and optimize important parameters, such as conductivity, field effect, contact resistance, and charge carrier mobility." This lays the foundation for developing, optimizing, and reproducing materials and processes for customized solutions that meet industry's specific requirements.
A selection of interdigital electrode chips and the new measurement adapter will be presented at Analytica 2026 at the Fraunhofer booth 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.
