Materials capable of varying their acoustic impedances to match those of air, water, and solid materials over broadband frequencies will enable new applications in fields as diverse as medical imaging, underwater sonar and communication, and marine biology. However, such tunability has not been achieved with conventional acoustic materials including metals, polymers, ceramics and woods. Here, the...
In article number 1903699, Nicholas X. Fang, Xuanhe Zhao, and co‐workers propose a meta‐gel to achieve tunable acoustic properties over air‐water‐solid ranges and broadband frequencies. The meta‐gel consists of patterned channels in a tough hydrogel matrix, where air, water, or liquid metal can be purged through the channels. The meta‐gel's acoustic impedance can be tuned by varying the geometry and...
