Abstract
This research proposes a scanning method on capacitance tomography known as Electrical Capacitance Volume Tomography (ECVT). This study discusses a new scanning method i.e., multistage scanning used to retrieve data from 64-channel capacitive sensor. The scanning process is divided into six groups which is each group can handle up to 24 electrodes. The experimental result were performed at each sensor level, followed by the first group on a multistage scanning, and finally for all 64-channel electrodes. The pattern of capacitance data in each group has a similar however its value is different. The amount of data in the first scanning group was 276 data, hence the total data for all 64 channels as much as 1656 data. An adjacent of electrodes pair produce a capacitance value of about 0.8 pF to 1.5 pF, while the opposite of electrodes pair produce a capacitance value of about 0.2 pF.
