摘要：
An example system for estimating a hydration level of an individual can include: a mechanism configured to apply mechanical pressure to a digit of the individual； an light detector configured to sense the light from the digit； and a controller programmed to perform functions including: send a first signal to the mechanism to apply the mechanical pressure to the digit； send a second signal to the mechanism to release the mechanical pressure on the digit； determine a capillary refill time based upon a third signal from the light detector indicating an amount of time for capillaries of the individual to refill with blood； and estimate the hydration level of the individual based upon the capillary refill time and one or more additional parameters.
