A wireless sensor antenna system for a turbomachine including a rotating blade including a passive sensor is disclosed. The wireless sensor antenna system includes an antenna extending continuously along a circumferential interior surface of a casing of the turbomachine that surrounds the rotating blade. The antenna is configured to receive a return wireless signal from the passive sensor. A power transmission element extends along the at least portion of the circumferential interior surface of the casing to power the passive sensor by emitting an electromagnetic signal to power the passive sensor.

A passive sensor network constituted by a reader (5), wireless energy emitters (2), and fully passive sensors (1) is described. The passive sensors allow continuously the data collection and transfer thereof whenever requested by the reader, via backscatter at a frequency (4), and in parallel the reception of energy from the transmitters (3). Each sensor integrates an antenna, two impedance matching networks, a semiconductor, a microcontroller and one or more sensors that do not require the use of their own power supply or batteries. The reader (remote unit) initiates the communication process. This communication is achieved by sending radio frequency commands recognized by the passive sensors. These sensors, upon receiving the commands from the reader, initiate the back transmission of data according to the received command. The power transmitters are used to allow continuous power supply of the passive sensors.

Disclosed is a system which extends NFC near field communication over a user's skin by converting electromagnetic signals into modulated alternating electric fields and vice versa. A modified patch is attached to an NFC device, which gets energized from its electromagnetic resonance which may contain data. The patch uses the energy to create an alternating electric field which couples into and spreads over a user's skin. The user may approach or touch objects which then get energized by the alternating electric field. The objects have a tag which modulates the electric field with data back over the user's skin to the patch, which then demodulates the data to modulate the NFC communication of the NFC device for further processing.
