DEVICE FOR CONVERTING MECHANICAL ENERGY FROM SOUND WAVES INTO ELECTRICITY

摘要

A device (10) for converting sound waves into electricity comprising first and second electrodes (12, 14) connected to a voltage or current source (32) and intended to be connected to a load (34), the first and second electrodes together delimiting a recess (16) intended to receive infrasound and partially filled with a powder (19) of a semiconductor material and an electrolyte (18) comprising a colloidal dispersion of electrically charged diamond nanoparticles in a dispersing liquid medium comprising water or containing a gaseous mixture likely to form a plasma, the gaseous mixture comprising at least one metal in gas form.
