摘要： By combining at least two strain sensors in a symmetric configuration, a dual use sensor may be realized. This may reduce the footprint, cost, and complexity of employing two different sensors. It may also improve the accuracy of the measurements as two different parameters i.e., strain and environmental information are measured at the same physical location. This dual use sensor may be deployed in an array over a large area or space, providing systemic information of the subject that is previously difficult to detect.

摘要： Nanocomposite sensing materials are formulated with low aspect ratio conductive fillers with close to or higher than percolation threshold in a low Poisson's Ratio matrix binder with a high gauge factor, low temperature coefficient of resistance (TCR), low temperature coefficient of gauge factor (TCGF), and low hysteresis.

摘要： Transparent nanocomposites may be used as force sensing materials, either as a transparent piezo-resistive material for resistive force sensing or a transparent dielectric material for capacitive force sensing. The common aspect of these nanocomposites is to engineer the refractive index of the binder to the index of the fillers so that when incorporated into a force sensor the nanocomposite films are optically transparent.

摘要： A hybrid strain sensing system and the method of making such a system provides a thin semiconductor film with strain sensors and signal processing circuits integrated deposited thereon. The semiconductor film may be further processed and then mounted onto a substrate to be used for strain, force, or other related measurements. The system combines the high sensitivity of a semiconductor strain gauge with the high level of integration of semiconductor integrated circuits (IC)s. Both are highly desirable features for applications where miniaturization and/or flexibility are important requirements.
