Users can now develop their own battery-free sensors or actuators on the tag. The Medusa harnesses energy from the radio frequency field created by the RFID reader and powers the ANDY100 chip, the microcontroller, and any additional circuitry and components.
The ANDY100 chip uses the standard EPC C1G2 protocol, and no proprietary commands are required. Any commercially available UHF RFID reader can be used if the software is programmed with the correct standard commands.
