Hydration/dehydration of body - How can I measure It

[gojcus]

Hello!

 

I'm working on a project about body/skin de/hydration. I'm interested if there is already a known technique or technology with which we could measure body/skin de/hydration in a simple/easy and quick way?

I know that there are already certain techniques/technologies which are measuring de/hydration, (for example urine and blood tissue testing), but I would like to know if there is a faster and more simple technique/technology which we could use in our daily routine(and if it is also accurate)?

When I was looking for answers I found those techniques/technologies:

 

- Fingerprint senzor

 

- Corneometer

 

- Nova DPM

 

- Pulse oksimetre

 

- Bioelectrical impedance analysis (BIA)

 

- Moisture checker

 

- Opto-thermal transient emission radiometry (OTTER)

 

Which of this is most accurate and fast? Are there any other appropriate?

 

Thank you for your time and your answers!
