"bypasses thermodynamic limits... microscopic sound vibrations controlling electrical charges movement within 2D materials... sound waves shift whether electrons/ holes dominate material's channel, reversing electrical current direction... multi-bit memory element prototypes vastly boost data storage density within a single cell... created the first surface acoustic wave -controlled artificial synapses, paving the way for highly efficient, biologically plausible AI hardware with expanded dynamic range... edge AI"
