Title:
POWER GENERATOR
Document Type and Number:
Japanese Patent JP2015161229
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power generator capable of achieving improvement of the generation efficiency.SOLUTION: A power generator 1 includes a power generating element 3 and a housing 2. The power generating element 3 includes: a support part 31; a vibration part 32; and a piezoelectric conversion part 33. A first end 32a and second end 32b in the vibration part 32 respectively form a fixed end and a free end. The piezoelectric conversion part 33 is provided overlapping with a part of a surface 321 of the vibration part 32 and generates AC voltage by vibration of the vibration part 32. The housing 2 includes: a fluid inlet 21; a fluid outlet 23; a passage 22; and a fluid introduction part 24 which gathers a fluid flowed from the inlet 21 to the power generating element 3. The power generating element 3 includes a surface area increase part 325 which is formed on the surface 321 of the vibration part 32 by a protruding part and increases a surface area of the vibration part 32.
