WEARABLE DEVICES INCORPORATING ION SELECTIVE FIELD EFFECT TRANSISTORS

摘要

Techniques for measuring ion related metrics at a user's skin surface are disclosed. In one aspect, a method for operating a wearable device may involve determining, based on output of one or more ion selective field effect transistor sensors, various physiological conditions such as a state of hydration, a state of skin health, or the cleanliness of the wearable device or an associated garment.
