    Abstract: A flexible cable is provided. The flexible cable includes a first insulation part, a second insulation part disposed on the first insulation part, a first group of ground parts disposed at regular intervals under the first insulation part, at least one transmission line disposed at regular intervals under the first insulation part and alternately arranged with the first group of ground parts, an air gap formed under the first insulation part, a prepreg layer disposed under the first insulation part, and a third insulation part disposed under the air gap and the prepreg layer. The air gap is configured to prevent signals emitted from the at least one transmission line from propagating in a direction of the air gap. Hence, it is possible to shield electromagnetic interference with other electronic components while minimizing the signal loss.

    Abstract: An apparatus for detecting biometric information of a living body detects a pulse wave and extracts the biometric information of the living body in a non-invasive method. The apparatus for detecting biometric information includes a surface pulse wave measurement unit for measuring a surface pulse wave of an object. The surface pulse wave measurement unit includes at least one light source that radiates incoherent light and at least one photodetector that measures an intensity of light radiated by the at least one light source and reflected from a surface of the object. The surface pulse wave measurement unit measures the surface pulse wave of the object based on a change in the intensity of the light reflected from the surface of the object.
