RFID device with two-stage power harvesting
View Patent ↗Disclosed is a method of gathering data from a hybrid RFID chip to determine usage of an item or article of clothing using a mobile device like a phone, laptop, or tablet. The hybrid RFID chip consists of a processor, a memory, a radio transceiver, a power harvesting antenna, and an impedance circuit that converts ambient radio frequency (RF) energy to electrical energy. The RFID chip receives a first power level from ambient RF energy and periodically broadcasts an identity. The mobile device can receive the broadcast identity, store the identity, transmit the identity and location to a remote server, and receive a notification message from the remote server. The remote serve can determine usage of the item or article of clothing by comparing current records to previous records of RFID chip identity, location, and mobile device application identity.
1. A textile fabric system, comprising:
an article made from textile fabric, comprising,
a textile fabric,
a seam;
a radio Frequency Identification (RFID) chip retained by the seam, comprising,
a non-transitory memory,
a processor,
a radio transceiver,
an energy harvesting antenna,
an impedance circuit configured to convert energy received from the energy harvesting antenna to a first electrical energy level by ambient radio frequency signals and a second electrical energy level by proximate radio frequency signals,
an energy storage device configured to store electrical energy,
an application stored in the non-transitory memory that, when executed by the processor in response to a first electrical energy level, transfers an RFID identification to the radio transceiver to broadcast in a first radio frequency signal;
a user equipment (UE), comprising,
a processor,
a memory,
a short range radio transceiver,
a long range radio transceiver,
