At the CUNY Graduate Center, a team of physicists has borrowed an insight from the quantum world of electronics and applied it to the ancient problem of controlling sound. By rotating precisely engineered material layers against one another, they have discovered that mechanical waves — the vibrations underlying ultrasound, sensing, and signal processing — can be steered, focused, and reconfigured without rebuilding the device that carries them. The discovery, named twistelastics, suggests that the rigid, single-purpose designs long governing these technologies may give way to systems as adapta
