1. A batteryless wireless sensor device comprising:
an impedance matching network operably coupled to an antenna and configured to receive a radio frequency (RF) signal that is transmitted from another device;
a power rectifier operably coupled to the impedance matching network and configured to harvest energy from the RF signal and generate a DC signal based on the energy harvested from the RF signal; and
a wireless sensor device operably coupled to the power rectifier and the impedance matching network, powered by the DC signal, and configured to:
perform digital sampling of a sensor signal of a sensor thereby generating sensor data; and
facilitate transmission of the sensor data to the another device by facilitating modulation of impedance of the impedance matching network to transmit the sensor data to the another device by facilitating reflection of energy of the RF signal that has been transmitted by the another device.
