Self-powered electrochemical sensors have the potential to advance the field of electrochemical sensors by providing energy and material savings, using the two-electrode galvanic cell principle instead of the three-electrode cell method employed by potentiostatically controlled methods. Our article „Selection of Anode Half-Cells for Hydrogen Peroxide Self-Powered Electrochemical Sensors Using Biomimetic Metal Complex Cathode Catalysts” provides novel insights into the operation mechanism of the self-powered electrochemical sensors for the determination of hydrogen peroxide.

Our publication, “Pullulan Coating Preserves High Conductivity in Cable Bacteria Wires,” shows how a thin polysaccharide layer (pullulan) boosts the stability of conductive cable bacteria by ten fold and explores a link between their conductivity and ambient humidity.

Our colleagues from IBI-3, RWTH Aachen and colleagues from Polytechnique Montréal, Canada have published (16.07.2024) a paper in Neuromorphic Computing and Engineering. The paper examines the behavior of biogel-based organic electrochemical transistors (OECTs) using PEDOT:PSS as the channel and gate material and investigates the impact of electrolyte viscosity and cation diffusivity on short-term plasticity, as well as the effect of neurotransmitter-mediated long-term plasticity.
