New publication by Wolfgang Knoll, Christoph Kleber, Jakub Dostalek and Roger Hasler together with colleagues from the University School for Advanced Studies (IUSS) in Pavia, Italy, and the Department of Electrical and Electronic Engineering, University of Cagliari, Italy, titled “A hybrid OTFT-SPR system for simultaneous electronic and optical sensing”.

This research highlights the development of a flexible multivariable sensing platform that integrates an extended-gate organic thin-film transistor (ExG-OTFT) with surface plasmon resonance (SPR) detection. We demonstrate how this hybrid system overcomes key limitations of earlier designs by combining electrical and optical sensing on a unified, low-cost, printable substrate. The platform offers simultaneous detection of surface mass and charge variations. With its enhanced reliability, scalability, and compatibility with commercial SPR setups, this system paves the way for cost-effective, disposable multivariable sensors for a broad range of applications in materials science, healthcare, and environmental monitoring.
