Gii-Sens - Pure 3D Porous Graphene Sensing Strip Electrode (SSE)

The Gii-Sens 3D Pure Porous Graphene Electrode (4 mm) is a next-generation electrochemical sensor engineered for ultra-sensitive, low-noise measurements in a flexible and compact format. Unlike conventional carbon-based screen-printed electrodes, Gii-Sens features a laser-induced 3D porous graphene layer directly formed on a polyimide substrate (Kapton®) using laser pyrolysis technology.

This binder-free and ink-free fabrication method yields a high-purity graphene surface with exceptional electrochemical activity, large electroactive area, and excellent signal-to-noise performance. The porous architecture significantly enhances electron transfer kinetics, making it ideal for applications in biosensing, environmental testing, wearable diagnostics, and point-of-care devices.

The Gii-Sens electrodes are batch-fabricated using high-precision laser systems, ensuring excellent reproducibility and structural consistency.
