A Cell Impedance Measurement System

نویسنده

  • Jonathan Choy
چکیده

A cell-impedance measurement system is presented that can measure an effective parallel resistance and capacitance of a cell to within 1% in 1ms. It is proven to be functional at ten logarithmically-spaced frequencies between 100 kHz and 100 MHz, with ten parallel structures simultaneously calculating each of these. This system is further shown to be implementable with commercial parts – namely a Maxim MAX121 ADC, a Maxim MAX275 filter, and a Linear Technology LT1794 op-amp.

Phase Angle Measurement in Healthy Human Subjects through Bio-Impedance Analysis

Objective(s)Bioelectrical impedance is the measure of impedance of the body. Impedance consists of electric resistance and reactance. Phase angle (PA) is the tan value of the ratio of reactance versus electric resistance. PA depends on cell membrane integrity and on body cell mass. There exists a correlation between PA values and body cell mass.The objective of this study was to compare the PA ...

قلب نگاری امپدانسی روشی برای پایش غیرتهاجمی حجم ضربه ای: یک مطالعه ی مقدماتی

 Abstract Background: Impedance cardiography (ICG) is a simple and inexpensive technique for non-invasive and continues measurement of stroke volume. Due to non-invasive nature, ICG is becoming increasingly used in research and clinical applications. With regard to lack of domestic impedance cardiograph and limited similar imported products in the country, an inexpensive and portable protot...

Theorical Investigation of Linear Response for Passivated Metallic Electrode Under Potential Step (RESEARCH NOTE)

The transient response of passivated metallic electrode system under potential step was analyzed based on a linear model, and a technique for calculating the parameters characterizing the growth and dissolution of passive film was proposed. It is believed that the information which is expected to be gained from the impedance measurement can be obtained by this technique and that this technique ...

Classification of cell types using a microfluidic device for mechanical and electrical measurement on single cells.

This paper presents a microfluidic system for cell type classification using mechanical and electrical measurements on single cells. Cells are aspirated continuously through a constriction channel with cell elongations and impedance profiles measured simultaneously. The cell transit time through the constriction channel and the impedance amplitude ratio are quantified as cell's mechanical and e...

Grid Impedance Estimation Using Several Short-Term Low Power Signal Injections

In this paper, a signal processing method is proposed to estimate the low and high-frequency impedances of power systems using several short-term low power signal injections for a frequency range of 0-150 kHz. This frequency range is very important, and thusso it is considered in the analysis of power quality issues of smart grids. The impedance estimation is used in many power system applicati...
