Abstract
A wireless ECG sensor system includes a sensor patch configured to attach to a user. The sensor patch may include a substrate having a positive and a negative electrode, and a passive radio-frequency identification (RFID) transponder carried by the substrate. The RFID may include a first antenna, a non-transitory and non-volatile storage medium in electrical communication with the first antenna, a load modulation switch in electrical communication with the first antenna, and a microcontroller in electrical communication with the first antenna and in data communication with both the storage medium and the load modulation switch. The system may also include an interrogator device having a second antenna configured to wirelessly transmit electromagnetic radiation having a resonant frequency of the first antenna of the sensor patch, and a demodulator configured to measure a voltage amplitude of the electromagnetic radiation wirelessly transmitted by the second antenna.
