<p>An electrical energy generator (10) comprises a cylindrical stator (12), a cylindrical liner of a piezoelectric material (14) in concentric contact with the stator (12), and an armature (56) rotatable about the liner (14). In one embodiment, as the armature (56) rotates, the armature (56) squeezes successive portions of the liner (14) against the stator (12) for alternately compressing and decompressing the liner (14) portions for causing them to generate electrical energy. In another embodiment, the armature (56) causes alternating stretching and destretching of successive portions of the liner (14) between spaced apart portions of the stator (12) for causing the liner (14) portions to generate electricity.</p> |
