PAGE TITLE
Overview
PAGE SUMMARY
Energy storing and harvesting textiles are currently being developed at Drexel University. Antennas are tuned to harvest or scavenge energy at 2.4 GHz from the WiFi frequency band. The antenna is fully knitted from conductive yarns on industrial knitting machines. The antenna is connected to a small circuit that can collect the harvested signals for specific applications. This harvested energy can either be used to power other textile devices, or can be stored in a supercapacitor, which is embedded in the same piece of fabric. Custom fitted pockets can be made to house non-textile components, and conductive leads can be knitted as a part of the fabric to connect all system components.
APPLICATIONS
TITLE: Applications
Power other wearable electronics
Power small portable electronics
Can be incorporated into interiors to store charge collected from other renewable sources
Flexible and stretchable electronic applications
ADVANTAGES
TITLE:Advantages
Passive system, no need for the wearer to be moving to harvest energy
When no WiFi is available, devices can draw power from the energy storage device
Mass customization in terms of size, material, and device configuration
Manufacturing processes are readily scalable
