Abstract: A biological information measurement device includes a sensor unit that detects predetermined biological information related to an organ of a living body, an A/D conversion unit that converts a measurement signal output from the sensor unit into a digital signal, a storage unit that stores information including a digital signal related to the measurement signal output from the A/D conversion unit, an analysis processing unit that determines presence or absence of a suspicion of an abnormality in the organ by analyzing the digital signal, and a measurement control unit that changes a sampling frequency related to A/D conversion of the measurement signal under a predetermined condition when the analysis processing unit has determined that a suspicion of an abnormality is present in the organ.

Abstract: Provided is an electroacoustic converter film including thin film electrodes provided on both surfaces of a polymeric composite piezoelectric body in which piezoelectric body particles are dispersed in a viscoelastic matrix formed of a polymer material that exhibits viscoelasticity at normal temperature, and protective layers formed on the thin film electrodes. The electroacoustic converter film further includes electrode lead-out metal foils laminated on the thin film electrodes, and the electrode lead-out metal foils allows connection to wiring through soldering when electrodes are led out from the thin film electrodes.
