Abstract
A power collector structure connected to a base is repetitively deformed or bent. The power collector structure is bar-like, and is connected to the base in an essentially rigid manner. A power collector for converting mechanical energy to electric power is connected to the power collector structure.
Claims27
A power collector structure connected to a base that is repetitively deformed or bent in rotational motion,
- wherein
- the power collector structure is bar-like,
- the power collector structure is connected only at one end of the bar-like structure to the base,
- the one end of the power collector structure is connected to the base in an essentially rigid manner,
- the power collector structure extends radially from the base,
- a power collector for converting mechanical energy to electric power is connected to a tip of the power collector structure, wherein the tip is opposite to the one end of the power collector structure connected to the base, and
- wherein the tip of the bar-like structure is configured to vibrate when the base is deformed or bent to produce the mechanical energy.

A method for collecting power of a base that is repetitively deformed or bent in rotational motion, in which method a power collector structure is being used, said method comprising:
- connecting only one end of a bar-like power collector structure essentially rigidly to the base such that the power collector structure extends radially from the base;
- and
- converting mechanical energy to electric power by a power collector at another end of the power collector structure opposite to the one end,
- wherein the another end of the bar-like power collector structure is configured to vibrate when the base is deformed or bent to produce the mechanical energy.
