1. A biosignal processing apparatus comprising:
- a biosignal measurement module that comprises a prism and a spectroscope and is configured to detect a biosignal of a subject in a non-invasive manner while the prism is in contact with the subject;
a touch sensor configured to bend to cover a three-dimensional shape of the subject, measure a change in an amount of charges carried in the touch sensor, and determine a contact area between the prism and the subject based on the change in the amount of the charges carried in the touch sensor, a contact surface of the touch sensor and a contact surface of the prism being disposed on a same plane with respect to the subject while the contact areas of the touch sensor is being measured; and
a controller configured to control the biosignal measurement module to start measuring the biosignal in response to determining that the contact area between the prism and the subject being equal to or greater than a reference value,wherein the touch sensor is disposed to surround the prism, and boundaries of the contact surface of the prism are entirely in contact with boundaries of the contact surface of the touch sensor.

Abstract
Provided are a biosignal processing apparatus and a biosignal processing method. The biosignal processing apparatus includes: a first measurement module configured to detect a biosignal of a subject in a non-invasive manner in response to the biosignal processing apparatus being in contact with the subject; a second measurement module configured to measure a contact state with respect to the subject; and a controller configured to determine whether the contact state is equal to or greater than a reference value.

10. A biosignal processing method of a biosignal processing apparatus including a prism and an touch sensor, the method comprising:
-
measuring a change in an amount of charges carried in the touch sensor while a contact surface of the touch sensor and a contact surface of the prism are disposed on a same plane with respect to a subject; determining a contact area between the prism and the subject based on the change in the amount of the charges; and measuring a biosignal of the subject in a non-invasive manner in response to the determined contact area between the prism and the subject being equal to or greater than a reference value, wherein the measuring the change in the amount of the charges comprises measuring the change in the amount of the charges while the touch sensor is bend to cover a three-dimensional shape of the subject, and boundaries of the contact surface of the prism are entirely in contact with boundaries of the contact surface of the touch sensor. - View Dependent Claims (11, 12, 13)
