  • Patent number: 11796405
    Abstract: 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.

  • Publication number: 20230138119
    Abstract: A method for fabricating a strain sensing film, a strain sensing film, and a pressure sensor are provided in the present application. A semiconductor wafer is firstly thinned to form a semiconductor film. A die attach film is attached onto the semiconductor film. A resulting semiconductor film is diced to form a plurality of independent strain films. The plurality of independent strain films are transferred to a substrate, and the plurality of independent strain films are completely attached to the substrate. A metal pad of each of the plurality of independent strain films is electrically connected with a corresponding metal pad of the substrate. The plurality of independent strain films are packaged. In this way, the package process of the strain sensing film is completed, which tackles the problem that the existing COB packaging has defects when being applied to package the sensor film.

  • Patent number: 11248967
    Abstract: 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.

  • Patent number: 10908037
    Abstract: 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.
