Abstract
An embodiment of the present invention provides an apparatus, comprising a radio frequency identification (RFID) tag, wherein the RFID tag includes an antenna, and wherein at least one amorphous silicon or organic photovoltaic solar cell is integrated with the antenna.
Claims23
An apparatus, comprising:
- a radio frequency identification (RFID) tag, wherein said RFID tag includes an antenna;
- and
- wherein at least one amorphous silicon or organic photovoltaic solar cell is integrated with said antenna.
A method of powering an RFID tag, comprising:
- integrating at least one amorphous silicon or organic photovoltaic solar cell into an antenna included in said RFID tag, wherein an area of said at least one amorphous silicon or organic photovoltaic solar cell is optimized for a required power output and said at least one solar cell is a number of cells required for output voltage necessary for different loads and application and is sufficient to completely power said tag.
A method of manufacturing a solar powered RFID tag, comprising:
- depositing printable amorphous silicon or organic photovoltaics on a flexible substrate to form a solar cell as part of an antenna integrated with said RFID tag;
- using said antenna as bus bars, metal grids, or transparent conductors for said solar cell;
- and
- connecting a voltage source to a positive bus of said solar cell via a high-impedance trace.

An RFID tag, comprising:
- a multi-function antenna element wherein said antenna is adapted to simultaneously harvests radio frequency (RF) energy, communicate with an RFID reader, and harvests solar energy for auxiliary power;
- wherein said antenna uses printable amorphous silicon or organic photovoltaics deposited on flexible substrate to form part of said antenna's radiating structure to create at least one solar cell;
- and
- wherein an area of said at least one solar cell is optimized for a required power output and said at least one solar cell is a number of cells required for output voltage necessary for different loads and application and is sufficient to completely power said tag.
