Value to The Customer

Page 13: Group #10 January 20, 2011 Preliminary Design Review for EE495B Capstone Senior Design

Our Method

Use piezoelectric coax cable to generate mechanical energy.

Surround the piezoelectric coax cable with a durable mat.

Have a storage device to store harvested energy.

The electricity will then be used to charge a small device using a USB port.
