Project objectives:

The main goal of this project is the implementation of a pyroelectric detector array, for a prototype hyperthermia/diathermy apparatus designed and manufactured during the PhD thesis of this project proposal director. This goal will be reached in three passes: documentation, design plus experimental implementation and finally, testing of the resulted concept and the experimental setup.

Research Phases:

Phase I Documentation on the radiometric methods used in microwave thermal treatments focusing on microwave and pyroelectric radiometry

Research report

Phase II Implementing a radiometer device for temperature measurement in power microwave field

Research report

Modules designed and developed during the research time:

I2C isolator

Microwave applicator with

16 pcs thermopile array

USB to I2C converter

Phase III Testing the solutions

Research report



Experimental setup for applicator tests:

1- custom microwave generator (2.45GHz 10-300W),

2-thermostatic bath, 3-fiber optic thermometer,

4-applicator with embedded thermopiles array

5-agar-agar gel, 6-Acer Aspire E311 laptop

Microwave applicator prototype with

embedded thermopile array, front view


Expected results:

Phase I: Determining the optimal type of radiometer to measure the temperature of a relatively large surface sample, heated by microwave power irradiation field.

Expected dissemination: research report, web site, publishing an ISI article or participation to an international conference with ISI proceeding.


Phase II: Project for producing a thermopile sensor array embedded into a microwave slot applicator

Expected dissemination: research report, web site update, participation to an international conference, patent pending request.


Phase III: Laboratory tests using the experimental prototype of the microwave applicator with embedded thermopile array.

Expected dissemination: research report, web site update, publishing an ISI article
