Since most of the contact conduction type heart sound sensors don’t take into account acoustic signal attenuation problem caused by transmitting to a sensor whose filling materials’ impedance is different human soft tissue, signal-to-noise ratio (SNR) not very well. Human immersed in blood. If sensor’s core sensitive element can be fluid, may decreased greatly. Inspired principle hydroacoustic signal’s detection, this paper proposes design based on bionic vector hydrophone. Then theoretical...
In this paper, an electronic stethoscope is designed based on a bionic Micro-Electro-Mechanical System (MEMS) sound-sensitive sensor. Inspired by the strong sound reflection effect of water-air interface, double-sided diaphragm MEMS (DMES) encapsulated novel packaging proposed. The packaging's superiority verified comparing single (SMES) with DMES. frequency clinical heart signal mostly in range 20–600 Hz. Finite simulation results show that for same incident source, pressure level inside...
