Non-invasive medical examination using electric fields

A method of performing non-invasive medical examinations, in response to generated electric fields, comprising the steps of:

• locating human tissue in contact with a plurality of insulated electrodes mounted on a flexible dielectric membrane;
• and
• selecting a transmitting electrode and a monitoring electrode from said plurality of insulated electrodes, such that electric fields penetrate said human tissue, wherein:
• a first surface of a dielectric spacer is in contact with said flexible dielectric membrane;
• a window is provided between said first surface and a second surface of said dielectric spacer;
• an infra-red sensor is located on said second surface and is configured to receive infra-red radiation from said flexible dielectric membrane via said window, to determine a temperature of said flexible dielectric membrane, and further comprising the steps of:
• producing output signals derived from said monitoring electrode;
• and
• compensating said output signals with reference to said determined temperature.
