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.
Claims13
An apparatus, comprising:
- a radio frequency identification (RFID) tag to transmit a response to a signal from an RFID reader, and
- a first accelerometer coupled to the RFID tag;
- wherein the response is to include a multi-bit value indicating an amount of acceleration sensed by the accelerometer.
An article comprising
- a tangible machine-readable medium that contains instructions, which when executed by one or more processors result in performing operations comprising:
- transmitting a wireless poll to a radio frequency identification (RFID) tag;
- and
- receiving a wireless response from the RFID tag, the response including a value representing acceleration measured by an accelerometer coupled to the RFID tag.
