Hydrogel microphones for stealthy underwater listening
Conventional ceramic SONAR suffers from large acoustic impedance mismatch with water, rendering them easily detectable. Here, Gao et al. report a new design using a hydrogel filled with stimuli-responsive metal nanoparticles, which detects low-frequency sound with a high-sensitivity and zero-reflect...
