Abstract
An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator comprising a substantially annular high-permeability core, the core including at least one magnet therein to define a magnetic circuit, at least one rotatable bearing mounting the core to at least one bearing support, the at least one bearing permitting the core to pivot about a pivot axis, a gap provided in the core, a body of high-permeability material located in the gap, the body being spaced from respective end faces of the core by a respective spacing whereby pivoting movement of the core about the pivot axis causes relative movement between the end faces of the core and the body, and a rotationally fixed coil surrounding a length of the core coaxially with the pivot axis.
