  • Passive wireless antenna sensor for strain, temperature, crack and fatigue measurement
    Patent number: 9574966
    Abstract: An apparatus and method is provided for monitoring a condition of a structure using a passive wireless antenna sensor having a known resonant frequency when mounted on the structure. A signal is transmitted with sweeping frequencies around a known resonant frequency to the passive wireless antenna sensor. A signal is received from the passive wireless antenna sensor and a resonant frequency of the passive wireless antenna sensor is determined based on the received signal. The determined resonant frequency is then compared to the known resonant frequency, whereby a change in the resonant frequency indicates a change in the condition of the structure.

  • Passive wireless antenna sensor for strain, temperature, crack and fatigue measurement
    Patent number: 8868355
    Abstract: An apparatus and method is provided for monitoring a condition of a structure using a passive wireless antenna sensor having a known resonant frequency when mounted on the structure. A series of radio frequency signals are transmitted with sweeping frequencies around the known resonant frequency to the passive wireless antenna sensor. The passive wireless antenna sensor includes a dielectric substrate disposed between an antenna pattern and a ground plane such that a change in the condition of the structure will cause a change in one or more characteristics of the passive wireless sensor. A signal is received from the passive wireless antenna sensor and a resonant frequency of the passive wireless antenna sensor is determined based on the received signal. The determined resonant frequency is then compared to the known resonant frequency, whereby a change in the resonant frequency indicates a change in the condition of the structure.

  • Laser reflection optical fiber sensor
    Patent number: 8345264
    Abstract: A sensor, sensor assembly and a method of sensing, in which the sensor is in contact with a material or structure and the sensor directly measures one or more property changes in the material by means of light reflection and scattering using a reflective target.
