TRANSDUCER AND POWER-GENERATING SYSTEM USING SAME

Title:

TRANSDUCER AND POWER-GENERATING SYSTEM USING SAME

Document Type and Number:

WIPO Patent Application WO/2019/150850

Kind Code:

A1

Abstract:

This transducer (10) comprises: a piezoelectric element (20) having a piezoelectric layer (21) containing an elastomer and piezoelectric particles, electrode layers (22a, 22b) disposed so as to sandwich the piezoelectric layer (21), and elastic body layers (23a, 23b) disposed at least in the outermost layer; and an exterior material (30) accommodating the piezoelectric element (20). A buffer part (31) is demarcated between the piezoelectric element (20) and the exterior material (30) in the direction in which the piezoelectric element (20) extends under pressure, the buffer part accommodating at least one among a gas, a non-volatile liquid, and a solid that has a smaller elasticity than the elastic body layers (23a, 23b).
