| Summary: | 碩士 === 國立暨南國際大學 === 光電科技碩士學位學程在職專班 === 102 === Bio-medical technology has been closely linked with human life and plays a very important role in this paper is to propose a low-cost research and the application of a strong framework for microcontroller applications in biomedical science and technology can be applied to human cells impedance measurement.
If the application due to high-voltage perforation technique in human cells does not reverse seasonal need with pulse width modulation (PWM) to produce extremely short pulse duration of the pulse wave, avoid excessive damage to other normal cells. In this study, with the use of micro-processing circuit may generate a pulse duration of about 20 ns ~ 135 ns pulse is very short, which can effectively be applied to cause electroporation reduce damage to normal cells of human time.
In this paper, another study using a non-invasive way to measure the impedance of human cells, and made a two-dimensional grayscale graphical output, to quickly distinguish between normal cells and diseased cells purposes. This study uses micro-processing circuit can generate a sine wave with a constant current source, and through multiple sets of resistors and capacitors in parallel simulation of normal human cells and diseased cells impedance, and then do the sample measured data via computer to calculate the impedance of human cells, and finally the use of virtual instrumentation program will be divided into a gray area of human cells and white, gray part represents the high impedance of normal human cells, the white part of the body represents a low impedance diseased cells, with gray and white gray scale can make multiple sets of two-dimensional map like and to determine differences between normal cells and diseased cells.
