| Summary: | 碩士 === 元智大學 === 電機工程學系 === 96 === In this research, we want to develop a heating system by employing the property of cancer issue that the environment near the tumor is more acid than the surroundings.
According to the experiment data, we can make sure that the hydrogen ions, will make the impedance of physiological solution down. And by the formula of electricity, P=(V*V)/R , we know that if the impedance goes down, the power will raise up, and thus the tumor will heat up easier. Our experiments are focused on (1)To test and verify the effect of hydrogen ions (2)The variation of impedance in high frequency (3)To analyze the spectrum from the experiments.
In the result, there is a frequency that can make the heating efficiency best and in the spectrum analysis, we find out there is a similar trend with the variation rate of impedance.
At last we setup a platform for control by personal computer. This platform of control is in order to establish a basic thermal system which works by measuring the impedance in physiological solution.
