Design and implementation of CO2incubator to study the effect of Wi-Fi 6 signals on human cells

Abstract

In order to study the effect of Wi-Fi 6 signals on human cells, the do-it-yourself (DIY) CO2 incubator with electromagnetic (EM) shielding is designed and implemented. To maintain the temperature level between 36-37°C and CO2 level at 5 % (50, 000 ppm), the Arduino UNO r3 is used. The proposed CO2 incubator is compared with the commercial CO2 incubator by cell incubating test to confirm CO2 incubator's functions. To prevent unintentional effects from outside Wi-Fi signals, this paper proposes the EM shielding design using Ott's method [10]. From experimental results, it can be concluded that the cell incubating test result of the DIY CO2 incubator is similar to that of the commercial CO2 incubator, and the implemented EM shielding can reduce the 2.4 and 5 GHz Wi-Fi signals from outside up to 15 dB. Moreover, from the preliminary results of cell viability, it shows that there is no any significant effect of Wi-Fi 6 signals to WS-1 cell line. © 2021 IEEE.
