How to Measure a Benchtop Osmometer

Sally and Mike Wardian, two great ambassadors at the at the running event. So to pick those two athletes very specifically for what you're doing is very telling. What we did was basically create a flow path through this patch that has two electrodes. One of them is stimulating an electrical signal and the other one is receiving it. And in between is your sweat. When we get that impedance signal through the sweat, that's how we understand exactly what the electrolyte content is for fluid losses.
