Hydrophones play a crucial role in underwater target detection within sonar systems. However, existing hydrophones often encounter challenges such as low sensitivity and poor signal-to-noise ratio (SNR) in the detection of low-frequency acoustic signals. This work introduces a capacitive hydrophone (CH) designed for highly sensitive detection of …
At 40 mV s − 1, the capacitive contribution can reach 88 % confirming that a capacitive-based kinetics process determines the electrochemical performance. Furthermore, Fig. 6 h demonstrates that the specific capacitance is maintained at 80.78 % after 8000 cycles at 1 A/g, highlighting the device''s structural stability and excellent …
