ANALYTE INFORMATION DETECTION DEVICE, ANALYTE INFORMATION PROCESSING DEVICE, EARPIECE, AND EARPHONE

摘要

An analyte information detection device comprises: an analyte information detection unit (31) which is provided with a sensor attaching part which has an opening in a location that abuts an analyte, has a cavity therein that communicates with the opening, and forms a space structure in which the cavity is closed when mounted on the analyte, and a first sensor which detects a pulsatile signal based on pulse wave information of a blood vessel in the analyte as pressure information that originates from the pulsatile signal, is input through the opening, and is transmitted through the cavity; and a first frequency compensation process part (61) which performs a frequency compensation process, in which gain in the low frequency band is amplified, on a detection signal detected by the first sensor. The first sensor is a microphone which inputs sound signals from outside. The analyte information detection device outputs signals processed with the first frequency compensation process part.
