Abstract
An electric wave type biosensor includes: an electromagnetic wave irradiation unit; and a reflected wave receiving unit which receives a reflected wave and obtains an I signal and a Q signal. The electric wave type biosensor further includes: an I-Q norm angular velocity calculation unit which calculates an angular velocity and an IQ norm of the I signal and the Q signal, based on the I signal and the Q signal; a bio-information extract unit which extracts bio-information of the living body, based on the calculated angular velocity; and an output determination unit which determines whether the bio-information extracted by the bio-information extract unit is to be output based on whether a size of the calculated angular velocity is within a first threshold value.
Claims3
An electric wave type biosensor comprising:
- an electromagnetic wave irradiation unit which irradiates a body surface of a living body with an electromagnetic wave;
- a reflected wave receiving unit which receives a reflected wave obtained as the electromagnetic wave irradiated by the electromagnetic wave irradiation unit and then reflected on the body surface, and obtains an I signal obtained by multiplying the irradiated electromagnetic wave signal and the received reflected signal, and a Q signal obtained by delaying the I signal by a predetermined phase;
- an I-Q norm angular velocity calculation unit which calculates an angular velocity and an IQ norm of the I signal and the Q signal, based on the I signal and the Q signal which are obtained by the reflected wave receiving unit;
- a bio-information extract unit which extracts bio-information of the living body, based on the angular velocity calculated by the I-Q norm angular velocity calculation unit;
- and
- an output determination unit which determines whether or not the bio-information extracted by the bio-information extract unit is to be output based on whether or not a size of the angular velocity calculated by the I-Q norm angular velocity calculation unit is within a first threshold value.
