Abstract
A basketball that uses compression or decompression of piezo elements to produce current that charges a rechargeable battery in the basketball. The current is generated by the piezo elements that are placed between an inner shell and an outer shell of the basketball so that the bouncing of the basketball creates current to charge the battery. The charged battery can be coupled to an electronic device (e.g., smartphone) to charge the electronic device.
Claims9
A ball comprising:
- an inner shell formed with a first hole;
- an outer shell surrounding the inner shell and formed with a second hole;
- at least one piezo element between the inner shell and the outer shell;
- a circuit module including a rechargeable battery connected to the at least one piezo elements and housed in the ball, the rechargeable battery configured to be charged by current provided by the piezo element responsive to deformation of the piezo element due to external forces applied to the outer shell, wherein the circuit module is received in the first hole and the second hole;
- and
- a cover hinged to the outer shell to expose or cover the circuit module.
