Abstract: Disclosed herein are systems and methods for characterizing poroelastic materials. Indentation of a poroelastic solid by a spherical-tip tool is analyzed within the framework of Biot's theory. The present disclosure provides the response of the indentation force as well as the field variables as functions of time when the rigid indenter is loaded instantaneously to a fixed depth. Some embodiments of the present disclosure consider the particular case when the surface of the semi-infinite domain is permeable and under a drained condition. Compressibility of both the fluid and solid phases is taken into account. The solution procedure based on the McNamee-Gibson displacement function method is adopted.

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.

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.

Abstract: The condition of a structure using remote interrogation of a multi-state passive wireless antenna sensor that has a known resonant frequency when mounted on the structure. The passive wireless antenna sensor is connected to a remotely operated switching circuit that includes a photocell. An interrogation system transmits a series of radio frequency signals with sweeping frequencies around the known resonant frequency to the passive wireless antenna sensor, while simultaneously pulsing a laser to switch the passive wireless antenna sensor between a first state and a second state in which it is exposed to open-circuit or short-circuit conditions. A signal is reflected from the passive wireless antenna sensor in each of the first and second states, and a resonant frequency of the passive wireless antenna sensor is determined by normalizing the received signals to isolate the antenna mode.

Abstract: Devices, methods, and systems for wireless transmission of data from unpowered sensor nodes are presented. An unpowered sensor node includes a sensor, a first antenna for receiving an interrogation signal from a remote source, an up-converting frequency mixer, and a second antenna for transmitting a modulated output signal. A remote sensor interrogation unit generates and transmits the interrogation signal; then receives and demodulates the modulated output signal from the sensor nodes. Any type of sensor that generates an oscillatory signal can operate without a local power source. For a sensor that generates a non-oscillatory signal, the sensor node includes a low-power signal conditioning unit to convert the signal to an oscillatory signal. The sensor node may include an energy harvester such as a photocell to power the signal conditioning unit. A low-cost network of unpowered sensor nodes may be interrogated by a single interrogation unit using a multiplexing scheme.

Abstract: An optical fiber based polymer core sensor includes an optical fiber having a core and an end having a cured polymer core affixed to the core of the optical fiber. The cured polymer core extends outward from the end of the optical fiber and has a diameter approximately equal to the core of the optical fiber. Note the cured polymer core can be substantially cylindrical, tapered or geometrically shaped. The optical fiber based polymer core sensor can be used to measure a temperature, measure a strain, measure a distance, measure a refractive index, detect or measure an analyte, detect a toxin, detect a biological agent, monitor a chemical process, or a combination thereof.
