INDIVIDUALLY WEARABLE ELECTROMAGNITIC SENSING (iwEMS) SYSTEM AND METHOD FOR NON-INVASIVE ASSESSMENT OF TISSUE BLOOD AND OXYGEN CONTENT

A system for non-invasive in-vivo assessment of at least one physiological condition of tissue, comprising:

• at least one physiological sensor configured to monitor at least one circulatory physiological parameter of a subject and to generate at least one physiological signal indicative of the monitored physiological parameter, wherein the physiological parameter is indicative of temporal variations of blood circulation within a tissue portion containing a target tissue of interest;
• at least one radiation source configured to irradiate the tissue portion with electromagnetic radiation;
• at least one radiation detector configured to detect at least a portion of the irradiating radiation transmitted through or reflected by the tissue portion and to generate at least one detected radiation signal, wherein the radiation source and the radiation detector are configured, respectively, to generate and detect electromagnetic radiation frequencies in a range of about 0.01 GHz to about 10 GHz;
• and
• a digital processor configured to receive the physiological and detected radiation signals and process the signals to derive information regarding the at least one physiological condition within the target tissue,
• wherein the digital processor is configured to compute a cross-correlation function of amplitude between an amplitude of the at least one detected radiation signal and an amplitude of the at least one physiological signal.
