Smart Fabrics Generate Energy Several Ways

We see a great deal about wearable energy-generating fabrics, garments that will help keep the wearer warm, or cool, or visible because of built-in piezo-electric generators in the makeup of the fabric.  Several researchers are taking this to the next level, creating new warps and woofs of materials that will create energy from a greater range of energy inputs. Elias Siores and the University of Bolton In 2011, Professor Elias Siores and associates at the University of Bolton in the UK created a flexible fiber that could harvest energy from movement and light.  Siores said it was flexible enough to be woven into “a sail, window curtain or tent and generate power”.  The material was recognized as a major innovation …

Giving Power Walking a Whole New Meaning

Georgia Institute of Technology researchers have developed a self-charging power cell that uses a piezoelectric membrane to convert mechanical energy to chemical energy, then stores that energy until it can be released as en electrical current. Combining the power generator with the energy storage device, this hybrid is claimed to be more efficient than systems with separate generators and batteries.  When the piezoelectric membrane is flexed, it moves lithium ions in the power cell from one side of the cell to the other. Membranes in shoe heels and soles could produce power when a person walked, powering small electronic devices such as calculators or cell phones.
