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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"RFID device with two-stage power harvesting","description":"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.
