DOI: 10.1088/1361-6439/ab3dd1
Abstract: For piezo-resistive sensors have outstanding low-frequency response, micro-electro-mechanical system (MEMS) piezo-resistive vector hydrophones play an important role in low-frequency sound waves measurements. However, their signal-noise ratio (SNR) can be decreased by vibration noise. The conventional… read more here.
