BIOLOGICAL-SIGNAL-MEASURING APPARATUS, AND METHOD FOR ESTIMATING CONTACT STATE

Title:

BIOLOGICAL-SIGNAL-MEASURING APPARATUS, AND METHOD FOR ESTIMATING CONTACT STATE

Document Type and Number:

WIPO Patent Application WO/2015/056434

Kind Code:

A1

Abstract:

　The present invention pertains to a biological-signal-measuring apparatus and a method for estimating the contact state. A biological-signal-measuring apparatus (60) is attached to a living body and measures the biological signals of the living body, the biological-signal-measuring apparatus (60) being provided with an amplifier (62a), an analog-to-digital transducer (62b), a processing unit (63), an n-stage differential signal output unit (64a), and an output unit (65). The amplifier (62a) and the analog-to-digital transducer (62b) constitute a biological-signal-measuring unit (62) that measures biological signals from a biological signal sensor (61) and outputs a first signal corresponding to a biological signal. A temporal-change-rate signal output unit (64) is provided with the n-stage differential signal output unit (64a), into which the first signal is inputted and which outputs an n-stage temporal-change-rate signal (n being an integer of 1 or higher) of the first signal. The processing unit (63) functions as a contact state determination unit for determining the state of contact between the biological-signal-measuring apparatus (60) and the living body on the basis of the n-stage temporal-change-rate signal.
