摘要： A heart failure diagnostic device includes a piezoelectric sensor sheet having flexibility and configured to output a detection signal corresponding to an input vibration. A respiratory signal acquisition unit is configured to extract, as a respiratory signal, a signal of a vibration frequency caused by respiration from the detection signal detected by the piezoelectric sensor sheet. A power spectrum calculator is configured to obtain a power spectrum of a respiratory frequency band from the respiratory signal, and a signal corrector is configured to correct the detection signal such that in the power spectrum, a maximum value of a first-order frequency component of a respiratory waveform is not smaller than 1.5 times a maximum value of a second-order frequency component of the respiratory waveform to obtain the respiratory signal.

摘要： A flexible transducer includes: a dielectric layer including a semiconductor-containing layer that contains an elastomer and at least one of an inorganic semiconductor and an organic semiconductor; and a pair of electrodes disposed with the dielectric layer interposed therebetween, and containing a binder and a conductive material. The semiconductor-containing layer has a large dielectric constant and has high insulation properties. According to the flexible transducer, a large voltage can be applied between the electrodes, and a high output can be obtained.

摘要： A piezoelectric sensor (10) having an elongated-sheet shape includes a piezoelectric layer (11) containing an elastomer and piezoelectric particles and electrode layers (12a and 12b) which are disposed with the piezoelectric layer (11) sandwiched between the electrode layers. In the piezoelectric sensor (10), a pressure sensing region (S) has a length of 500 mm or longer in a longitudinal direction thereof; the electrode layers (12a and 12b) contain an elastomer and flaky conductive materials and are capable of elongating by 10% or more in one direction of plane directions; and when a space between one end portion (A) and the other end portion (B) of the pressure sensing region (S) in the longitudinal direction is set as a measurement zone, an electrical resistance in the measurement zone in the electrode layers (12a and 12b) is 3,000Ω or lower, and the specific Expression (I) is satisfied.
