Title:
BIOLOGICAL SIGNAL MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/089758
Kind Code:
A1
Abstract:
Sensor devices (1a, 1b) respectively comprise: amplification units (102a, 102b) that amplify biological potentials detected by electrodes (101a, 101b); FM transmission units (105a, 105b) that modulate carrier waves in accordance with the biological potentials, and wirelessly transmit the modulated signals to another sensor device; FM reception units (106a, 106b) that demodulate the modulated signals transmitted from the other sensor device and extract information about the biological potentials; reference potential generation units (107a, 107b) that generate reference potentials for the amplification units (102a, 102b); and correction units (1064a, 1064b) that correct the oscillation frequency of a voltage-controlled oscillator used in the demodulation by the FM reception units (106a, 106b).
