Patent ID: 8610335

Claim:
An electricity generating tire assembly comprising: a wheel rim; a tire having a tread and opposing sidewalls extending from said tread, said tire being coupled to said wheel rim forming an interior space between said tire and said wheel rim; an annular housing positioned in said interior space between said tire and said wheel rim, said housing having an annular outer wall, an annular inner wall and opposing side walls extending between said outer wall and said inner wall; a plurality of piezoelectric transducers extending outward radially from said outer wall of said housing, each said transducer having a base portion and a compressible distal portion relative to said housing, said distal portion of said transducer extending from said base portion when in an uncompressed state, each distal portion of each said transducer being positioned in said interior space in spaced relationship to said tread such that compression of said tread as said tire rotates compresses said distal portion of said transducer into said base portion of said transducer whereby said transducer produces electrical current; and a power cable having a first end extending into said housing, said power cable being operationally coupled to each said transducer for transmitting said electrical current through said power cable.
