Abstract: A sensor system for a laminated structure may include a sensor assembly disposed between a first layer and a second layer of the laminated structure. The sensor assembly may include a first anchor member and a second anchor member spaced at a predetermined distance from one another. A sensor chamber is formed between the first and second anchor members. The sensor assembly may also include a sensing line extending through the anchor members and the sensor chamber. The sensing line may include a configuration within the sensor chamber for sensing one of stress forces within the laminated structure, temperature or temperature changes within the laminated structure. A first transport tube may extend from the first anchor member opposite the sensor chamber and a second transport tube may extend from the second anchor member opposite the sensor chamber. The sensing line extends through the first and second transport tubes.

Abstract: A nanoparticle sensor apparatus includes a silicon-based nanoparticle having a centrosymmetric crystalline structure. A lanthanide atom embedded within the silicon-based nanoparticle provides light emission when the sensor apparatus undergoes pressure loading. This sensor apparatus may be encapsulated in a polymer matrix to form a nanoparticle sensor matrix apparatus which may be located on or in a structure. To measure the pressure on such a structure, a UV light source illuminates the sensor apparatus. An optical emission detector detects the intensity of light emitted from the sensor in response, while a processor correlates that intensity to the pressure loading.

Abstract: Systems and methods of sensing intraocular pressure are described. An example miniaturized intraocular pressure (IOP) monitoring system is provided using a nanophotonics-based implantable IOP sensor with remote optical readout that can be adapted for both patient and research use. A handheld detector optically excites the pressure-sensitive nanophotonic structure of the IOP-sensing implant placed in the anterior chamber and detects the reflected light, whose optical signature changes as a function of IOP. Optical detection eliminates the need for large, complex LC structures and simplifies sensor design. The use of nanophotonic components improves the sensor's resolution and sensitivity, increases optical readout distance, and reduces its size by a factor of 10-30 over previous implants. Its small size and convenient optical readout allows frequent and accurate self-tracking of IOP by patients in home settings.
