Title:
BIOSIGNAL MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/047838
Kind Code:
A1
Abstract:
This biosignal measurement system is provided with two first electrode device (100a) and second electrode device (100b), a right foot drive device (120), and a biosignal generation device (130). The biosignal generation device (130) is provided with a midpoint potential calculation circuit (134) that uses biopotential information that has been transmitted respectively from the two first electrode device (100a) and second electrode device (100b) and received by a first wireless receiver (131) to determine a midpoint potential and a second wireless transmitter (135) that wirelessly transmits the midpoint potential to the right foot drive device (120), wherein the right foot drive device (120) includes: a second wireless receiver (121) that receives the midpoint potential transmitted from the second wireless transmitter (135); an amplification circuit (122) that amplifies the midpoint potential received by the second wireless receiver (121); and a second electrode (123) that applies to a human body the midpoint potential amplified by the amplification circuit (122).
