Title:
POWER GENERATION ELEMENT, POWER GENERATION MODULE, ROTATION SPEED DETECTOR, AND POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2024/084701
Kind Code:
A1
Abstract:
This power generation element (10) comprises a plurality of magnetic wires (11) that exhibit a large Barkhausen effect, a pickup coil (12) that is wound on the circumference of a bundle of the plurality of magnetic wires (11), and magnetic connection members (13) that magnetically connect respective end sections of the plurality of magnetic wires (11) to each other at both ends of the plurality of magnetic wires (11). When a magnetic field applied to the magnetic wires (11) reverses, the magnetic wires (11) cause the pickup coil (12) to generate a pulse voltage due to the large Barkhausen effect.
