Development of conductive inks for 3D-printed microelectrode arrays in electrophysiology
September 02, 2025
Lukas Zeipelt has just finished his research project on the development of conductive inks for 3D-printed microelectrode arrays in electrophysiology.
Project Description:
Conductive polymers exhibit mechanical properties like traditional polymers, opening the door to 3D-printing, while also exhibiting conductivity up to 1200 S/cm. However, their use for 3D printing is hampered by the low availability of ink formulations and low resolution. This project provides an approach to formulate 3D-printable conductive inks based on deep eutectic solvent for MEA fabrication.

BioAct: self-powered biodegradable pressure sensor for wireless post-surgical patient management.
About the project
The project aims to develop a self-powered biodegradable pressure sensor with the potential for wireless data transmission that is tested in vitro under conditions that mimic the in vivo environment of physiological blood flow. The pressure sensor is based on the self-powered triboelectric nanogenerator technology and will combine components that enable high performance and on-demand biodegradation. Sensor validation will be enabled by a hybrid mock circulatory loop: an in vitro system that simulate the dynamics of the healthy and pathological patient’s circulatory system. The method will enable to validate sensor-generated pressure signals against reference pressures generated by a digital patient representation

The latest article ‘P-type Accumulation Mode Organic Electrochemical Transistor Biosensor for Xanthine Detection in Fish‘ has been published in ACS Applied Materials & Interfaces.
In our latest research, we developed an OECT-based biosensor with a p-type polymer bithiophene–thienothiophene copolymer with tetraethylene glycol side chains, p(g42T-TT) as the channel material, aiming to monitor the quality of meat and fish product. The biosensor detects the xanthine level which reflects the degradation of meat and fish product. The results show the time-dependent of xanthine in fish samples from day 0 to day 6.
New article published in ACS Applied Materials & Interfaces
The latest article ‘In Situ Functionalization of Polar Polythiophene-Based Organic Electrochemical Transistor to Interface In Vitro Models‘ has been published in ACS Applied Materials & Interfaces.
In our latest research, we present the new conjugated polymer p(g42T-T)-8% OH, a promising material for simplifying the interface between biological systems and electronics. This polymer contains hydroxyl groups, enabling straightforward chemical modifications to control cell adhesion and growth on its surface. We demonstrate the fabrication of organic electrochemical transistors (OECTs) using p(g42T-T)-8% OH, which were successfully employed to monitor the formation of cell barriers in vitro. This research provides a valuable tool for studying biological systems and offers a pathway for developing customizable bioelectronic devices that more effectively interface with biological tissues.
