Overview

 

OPTICAL OXYGEN SENSORS

Advances in sensor materials and optoelectronics have enabled novel optical sensors. 

The principle of operation is to trap an oxygen-sensitive fluorophore in a coating that’s applied to the tip of a fiber or an adhesive patch

Oxygen Sensing Patches

Flexible patch material -- allows adhesion to curved surfaces

Silicone adhesive -- maintains optical clarity and mechanical hold to glass and plastics for months in aqueous environments; tested at pH 1 and 11, in DI water and seawater

Fast response -- <5 seconds without overcoat and <20 seconds with overcoat in both gas and liquid media
