Abstract

Official abstract text for this publication.

A cylindrical structure including a first cloth including a piezoelectric thread that generates an electric potential from external energy, a second cloth including a piezoelectric thread that generates an electric potential from external energy, and a connection portion connecting the first cloth and the second cloth, wherein the first cloth and the second cloth forms a side face of the cylindrical structure.

First claim

Opening claim text (preview).

The invention claimed is: 1. A cylindrical structure comprising: a first cloth that includes a first piezoelectric thread that generates a first electric potential from input of external energy; a second cloth that includes a second piezoelectric thread that generates a second electric potential from the input of the external energy; and a connection portion connecting the first cloth and the second cloth, wherein the first cloth and the second cloth form a side face of the cylindrical structure, and wherein the first piezoelectric thread and the second piezoelectric thread generate opposite charges. 2. The cylindrical structure according to claim 1 , wherein the connection portion is a joint portion between the first cloth and the second cloth and connects the first cloth and the second cloth. 3. The cylindrical structure according to claim 2 , wherein the joint portion connects the first cloth and the second cloth such that a hollow is formed between the first cloth and the second cloth. 4. The cylindrical structure according to claim 2 , wherein the joint portion has a higher friction coefficient than the first cloth and the second cloth. 5. The cylindrical structure according to claim 2 , wherein the joint portion has a higher hydrophilicity than the first cloth and the second cloth. 6. The cylindrical structure according to claim 2 , wherein the joint portion has a lower stretchability than the first cloth and the second cloth. 7. The cylindrical structure according to claim 2 , wherein the first cloth and the second cloth are knitted fabrics. 8. The cylindrical structure according to claim 7 , wherein the joint portion is a woven fabric. 9. The cylindrical structure according to claim 1 , wherein the first cloth and the second cloth further include an ordinary thread that does not generate an electric potential from the input of the external energy. 10. The cylindrical structure according to claim 1 , wherein at least one of the first piezoelectric thread and the second piezoelectric thread contains a chiral polymer. 11. The cylindrical structure according to claim 1 , wherein the connection portion connects the first cloth and the second cloth such that a hollow is formed between the first cloth and the second cloth. 12. The cylindrical structure according to claim 11 , wherein the cylindrical structure includes a plurality of first cloths and a plurality of second cloths, wherein the first cloths and the second cloths are arranged alternately along an axial direction of the cylindrical structure. 13. A cylindrical structure comprising: a first cloth that includes a first piezoelectric thread that generates a first electric potential from input of external energy; a second cloth that includes a second piezoelectric thread that generates a second electric potential from the input of the external energy; and a connection portion connecting the first cloth and the second cloth, wherein the first cloth and the second cloth form a side face of the cylindrical structure, wherein the connection portion connects the first cloth and the second cloth such that a hollow is formed between the first cloth and the second cloth, and wherein the cylindrical structure includes a plurality of first cloths that face each other across the hollow, and a plurality of second cloths that face each other across the hollow.
