Introduction

The patent is about the production methodologies of highly efficient flexible electrodes for potentiometric electrochemical devices based on InN / InGaN solid state materials. It permits to produce ultra-small compact integrated potentiometric sensors for wearable and implantable multiplexed sensor systems for the continuous monitoring of ions and macromolecular biomarkers for redundant and reliable healthcare and wellness/fitness tracking for the global population.

Technical features

The invention will permit to produce ultra-small, from centimeters down to fractions of millimeter size, compact integrated potentiometric sensors and multi-sensor arrays for wearable and implantable multiplexed sensor systems for the continuous monitoring of ions and macromolecular biomarkers for redundant and reliable healthcare and wellness/fitness tracking. Typical examples span from chlorine levels in the sweat, to understand hydration levels during sports, monitor glucose and cholesterol levels in the blood and the detect tumor progression and virus infections via specific biomarkers. The sensors and sensor arrays will be based on the discovery of super-Nernstian potentiometric response of InN/InGaN nanostructured materials in bio- and ion sensing, beating the theoretical, thermodynamic limit by currently almost a factor of two. On top, the InN/InGaN quantum dot material is inherently chemically stable, corrosion resistant, nontoxic, environmental friendly, bio-compatible and mechanically highly resilient.
