Wi-Fi Power Harvesting
The merging of two projects has resulted in the concept of harvesting power to charge a supercapacitor. The Haute Tech Lab in collaboration is developing a proof of concept for textile energy storage and harvesting. Antennas are tuned to harvest or scavenge energy at 2.4 GHz from the Wi-Fi frequency band. The antenna is fully knitted from conductive yarns on our industrial knitting machines. It 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.
