IPS PGU Series Electrochemical Workstation Helps High Stability Bipolar OECT Research

IPS PGU Series Electrochemical Workstation Helps High Stability Bipolar OECT Research, Customer Results Published in Science Advances

Recently, an important research result on high stability bipolar organic electrochemical transistor (OECT) was published in the international top academic journal Science Advances (April 15, 2026, Vol. 12, eaea9786). This study was jointly completed by Zheng Haoyu, Wang Ruizhe and other researchers, systematically revealing the synergistic effects of polymer structure, polaron dynamics and ion transport mechanism on the stability of OECT. It is noteworthy that PGU series electrochemical workstations produced by IPS Elektroniklabor GmbH & Co. KG were used in the key electrochemical characterization link of this study, which provided a strong guarantee for accurate acquisition of experimental data.      

In this study, the bipolar OECT based on P-6O polymer was analyzed in depth using multi-modal in situ operation techniques including EPR, XPS, GIWAXS, AFM and EQCM-D. Among them, the in situ electrochemical quartz crystal microbalance (EQCM-D) experiment was completed by the PGU electrochemical workstation of IPS Company and Q-Sense analyzer, which was used to accurately monitor the mass change and swelling behavior of polymer films during electrochemical doping. The experimental results show that the device exhibits very small mass change (<1%) and almost constant volume during both p-type and n-type doping processes, which significantly improves the cycle stability and lifetime of the device.   

PGU series electrochemical workstations are widely used in electrochemistry, materials science and biosensors due to their high accuracy, low noise and strong stability. The successful application in bipolar OECT research once again demonstrates its excellent performance in complex in-situ electrochemical measurements.      

IPS warmly congratulates the research team on their breakthrough results and remains committed to providing high-performance electrochemical test solutions to researchers around the world to facilitate more cutting-edge scientific discoveries.
