First Claim
Patent Images
1. An apparatus for measuring a biosignal, comprising:
- an optical source configured to emit a first light and a second light towards a target;
an inserted layer configured to transmit the first light and to reflect the second light; and
an optical detector configured to detect a first received light that corresponds to the first light reflected by or transmitted through the target, and to detect a second received light that corresponds to the second light reflected by the inserted layer.

Abstract
An apparatus and a method of measuring a biosignal are provided. The apparatus of measuring a biosignal includes an optical source configured to emit a first light and a second light towards a target, an inserted layer configured to transmit the first light and to reflect the second light, and an optical detector configured to detect a first received light that corresponds to the first light reflected by or transmitted through the target, and to detect a second received light that corresponds to the second light reflected by the inserted layer.

14. An apparatus for measuring a biosignal, comprising:
-
an optical source configured to emit a light towards a target; an inserted layer configured to transmit the light; an optical detector configured to detect a light reflected by the target or a light transmitted through the target; and a displacement and force detector configured to detect either a change in displacement on a surface of the target or a change in contact force on the surface of the target. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method of a biosignal measuring apparatus to measure a biosignal, the method comprising:
-
emitting a first light towards a target; detecting a first received light corresponding to the first light either reflected by the target or transmitted through the target; emitting a second light towards the target; detecting a second received light corresponding to the second light that is reflected by an inserted layer; and obtaining biosignal information of the target based on at least one of the detected first light and the detected second light, wherein the inserted layer is configured to transmit the first light and to reflect the second light.
