Patent ID: 11962323
Assignee: SIGMASENSE, LLC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A batteryless wireless sensor device comprising:
a first impedance matching network operably coupled to a first antenna and configured to receive a radio frequency (RF) signal that is transmitted from another device;
a second impedance matching network operably coupled to a second antenna and also configured to receive the RF signal that is transmitted from the another device;
a first power rectifier operably coupled to the first impedance matching network and configured to harvest energy from the RF signal and generate a first DC signal based on the energy harvested from the RF signal;
a second power rectifier operably coupled to the second impedance matching network and configured to operate cooperatively with the first power rectifier to harvest the energy from the RF signal and to generate the first DC signal based on the energy harvested from the RF signal;
a voltage regulator operably coupled to the first power rectifier and the second power rectifier and configured to process the first DC signal generated cooperatively by both the first power rectifier and the second power rectifier to generate a second DC signal based on the energy harvested from the RF signal; and
a wireless sensor device operably coupled to the voltage regulator, the first impedance matching network, and the second impedance matching and configured to facilitate transmission of sensor data to the another device.
