Abstract
A method of operating a wireless ECG sensor system may include (1) wirelessly transmitting, using a second antenna, electromagnetic radiation having a frequency equal to the resonant frequency of a first antenna of a sensor patch; (2) inductively receiving, using the first antenna, power for operating a passive RFID transponder of the sensor patch; and (3) operating the microcontroller of the sensor patch to perform at least one scan, wherein performing the at least one scan is defined as: (a) receiving a cardiac activity signal from at least one of the positive and negative electrodes of the sensor patch, (b) retrieving a location identifier from the storage medium of the sensor patch, and (c) operating the load modulation switch of the sensor patch to alter a voltage amplitude of the electromagnetic radiation to transmit to a demodulator a cardiac event reading comprising the cardiac activity signal and the location identifier.
