1. A sweat sensing system, comprising:
a mesh having a first surface for location over a sweat surface on which sweat is formed or collected, the mesh having a set of mesh openings extending through the mesh from the first surface to an opposite second surface of the mesh;
a vibration system for vibrating the mesh to provide oscillation adapted to nebulize sweat droplets such that the sweat entering the openings in first surface of the mesh is expelled as nebulized sweat droplets from the second surface of the mesh;
a condensing unit located over the second surface of the mesh for condensing the nebulized sweat droplets onto a sensing surface; and
a sweat sensor for biomarker sensing of the sweat condensed onto the sensing surface.
