Title:
SYSTEMS AND METHODS FOR FULLY WIRELESS AND BATTERYLESS LOCALIZATION AND PHYSIOLOGICAL MOTION DETECTION
Document Type and Number:
WIPO Patent Application WO/2024/064907
Kind Code:
A3
Abstract:
A battery-less, wirelessly powered localization system is described. In an embodiment, a wirelessly powered localization system, includes an external Tx antenna that generates a radio frequency (RF) signal that wirelessly powers a set of one or more localizers, an external Rx antenna that receives an output from the localizers, a localizer including: an Rx antenna that receives a radio frequency (RF) signal from an external Tx antenna, a passive four-stage full-wave CMOS rectifier that generates a DC voltage using the received RF signal, a low-dropout regulator that generates a stable DC voltage based on the rectifier-generated voltage, a frequency divider circuit to divide the frequency of received RF signal, and a Tx antenna that outputs an RF signal at the divided frequency to the external Rx antenna.
