Patent abstract
One or more accelerometers may be coupled to a radio frequency identification (RFID) tag, so that the response of the RFID tag indicates the acceleration being sensed by the accelerometer(s). In some embodiments the accelerometers may be powered from the RF energy harvested by the RFID tag from a received RF signal. The sensed acceleration indicated in the response may be used to determine a motion and/or an orientation of an object coupled to the accelerometers.
