Microwave Radiometry in Biomedical Temperature Monitoring
Summary
Microwave radiometry is a non-invasive technique for assessing internal tissue temperature by detecting naturally emitted microwave radiation. By combining highly sensitive radiometers with purpose-designed antennas and advanced signal-processing algorithms, it is possible to achieve accurate temperature readings from superficial and subcutaneous layers, as well as deep core regions. Key developments include refinements in antenna directivity and coupling, the implementation of adaptive calibration routines to correct for system drift and environmental influences, and the deployment of multilayer forward and inversion models to reconstruct three-dimensional temperature distributions. These advances underpin applications ranging from early detection of malignancies and inflammatory disorders to real-time monitoring of core temperature in critical care and wearable health platforms, with significant implications for personalised medicine and global health surveillance.

Microwave Radiometry in Biomedical Temperature Monitoring publication trend
The graph below shows the total number of articles in microwave radiometry in biomedical temperature monitoring across all publications each year (not limited to Nature Index journals).
Technical terms
Microwave radiometry: passive sensing technique that measures the power of microwave emission from biological tissues to infer internal temperature.
Brightness temperature: equivalent temperature derived from the measured microwave power, reflecting the radiative emission of the tissue.
Inversion algorithm: computational method that reconstructs internal temperature profiles from multilayer radiometric measurements.
Near-field antenna: specialised antenna designed to operate within electromagnetic near-field distances, improving sensitivity to shallow and deep tissue emissions.
