Development of portable standalone impedance measuring device for in vitro applications

Electrical impedance measurement of the biological samples has evolved as a new field in biomedical engineering. This is due to the fact that the electrical properties of the biological samples change considerably during diseased and healthy conditions. Unfortunately, the devices available in the market are bulky and are quite costly. In this study, we report the development of a portable, standalone, multi-frequency (50 Hz–10 KHz) impedance measurement device with acceptable accuracy and resolution for in vitro impedance measurement of the cells.
