System and method for detecting the state of hydration of a living specimen
First Claim
1. A system for non-invasive detection of the state of hydration in a living specimen, said system comprising:
- an RF generator/transmitter for emitting RF radiation signals at a plurality of frequencies and for transmitting said radiation signals through a tissue of a living specimen;
a receiver adapted to receive RF radiation Signals passing through the living specimen at the plurality of frequencies;
a processor; and
an indicator unit for providing an output signal representative of a hydration state of said tissue;
wherein said processor receives signals from said receiver and compares the intensity of the transmitted RF signals, at the plurality of frequencies, passing through said tissue with that of at least one reference value, indicating the state of hydration of said living tissue.

Abstract
The invention provides a system (2) for non-invasive detection of the state of hydration in a living specimen, the system including an RF generator/transmitter (416) for emitting RF radiation signals and for transmitting the radiation signals through a tissue of a living specimen; an RF receiver (8) for receiving RF signals transmitted through the tissue, and for feeding the signals to a processor (10) for comparison of relative attenuation of RF frequencies passing through the tissue with a reference attenuation ratio signal, and an indicator unit (12) for providing an output signal representative of the water content level of the tissue. A method for non-invasive detection of the state of hydration in a living specimen is also described and claimed.
