Abstract
An apparatus enabling a person to evaluate the hydration of a region of the skin or the mucous membranes. The apparatus includes a sensor including an array of non-optical detection cells and processor apparatus arranged to deliver at least one piece of information relating to the hydration of the region on the basis of signals coming from the sensor. A method for evaluation of hydration is also provided. The apparatus and method can also be used for evaluating, e.g., aging or the effectiveness of a treatment regimen.
Claims54
An apparatus enabling a person to evaluate the hydration of a region of the body with the region including at least one of a region of the skin and a region of mucous membranes, the apparatus comprising:
- a sensor comprising an array of non-optical detection cells, and
- a processor apparatus arranged to deliver at least one piece of information relating to hydration of the region based on signals coming from said sensor.
A method of evaluating the hydration of a region, the region including at least one of a non-dermatoglyphic region of the skin and a mucous membrane, the method comprising:
- applying a sensor to said region, said sensor comprising an array of non-optical detection cells;
- and
- picking up signals coming from said sensor and, on the basis of said signals, delivering information relating to hydration of said region.
A method of evaluating skin hydration, comprising:
- providing a fingerprint sensor having an array of capacitive detection cells integrated in at least one of a computer and a portable terminal;
- and
- using said fingerprint sensor for providing information relating to skin hydration.
A mobile telephone fitted with a sensor comprising an array of capacitive detection cells for application to at least one of a region of skin and a mucous membrane, said telephone including means for processing signals delivered by said sensor in order to deliver information relating to hydration of the at least one of a region of skin and a mucous membrane.
