We have sensor expertise for hand-held breath analysis and breathing-rate measurement products for regulated medical uses and for non-medically-approved consumer uses. Applications include more efficient drug-dosing by actuating dosing to synchronise with breathing, and detecting selected biomarkers, Our detector enables miniature low cost disposable handheld units. These very fast detectors give better resolution and accuracy, and instant start-up. The speed of our detectors also means that emitter cycles are shortened to save power and battery requirements. The detector is physically robust. Our customers are able to build smaller, cheaper disposable testers and dispensers with faster results and more efficient dosage.
