Title:
CURRENT MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/176412
Kind Code:
A1
Abstract:
This current measuring method, in which a voltage is applied to an electrode pair, and a biopolymer tunneling current passing between the electrode pair is measured, includes step a) to step d). In step a), the value of a tunneling current corresponding to a target inter-electrode distance is calculated. In step b), the value of a reference current flowing between the electrodes is measured using an inter-electrode distance at which no tunneling current flows between the electrodes. In step c), a target total current value is calculated by adding together the value of the tunneling current calculated in step a) and the value of the reference current measured in step b). In step d), the electrodes are arranged in target positions in which the value of a base current flowing between the electrodes matches the target total current value calculated in step c). In this way, the electrode pair can be arranged with a suitable inter-electrode distance in order to measure the biopolymer tunneling current passing between the electrode pair.
