Abstract

A sweat sensing system comprises a mesh for location over a sweat surface on which sweat is formed or collected, and a vibration system for vibrating the mesh to nebulize sweat droplets. The nebulized sweat droplets are condensed on a sensing surface, and a sweat sensor performs biomarker sensing of the sweat at the sensing surface.

Description

technical field [0001] The present invention relates to sweat sensing systems, such as sweat sensing systems for monitoring biomarkers in sweat. Background technique [0002] Non-invasive, semi-continuous and long-term monitoring of biomarkers indicative of disease / health status and fitness is a requirement for monitoring such as dehydration, stress, sleep, child health and perioperative monitoring. [0003] Sweat, tears and saliva can all be obtained non-invasively. Sweat is a particularly accessible biological fluid and is a rich source of information about a subject's physiology and metabolism. [0004] Continuous monitoring of high-risk patients (e.g., patients with severe chronic conditions, pre- or post-operative patients, and the elderly) using sweat biomarker monitoring devices can provide greater than usual higher quality diagnostic information. Such continuous monitoring could occur in a hospital setting or elsewhere. [0005] Human sweat alone or a mixture of ...
