    Abstract: In various embodiments, disclosed herein are systems and methods directed to the fabrication of a coreless semiconductor package (e.g., a millimeter (mm)-wave antenna package) having an asymmetric build-up layer count that can be fabricated on both sides of a temporary substrate (e.g., a core). The asymmetric build-up layer count can reduce the overall layer count in the fabrication of the semiconductor package and can therefore contribute to fabrication cost reduction. In further embodiments, the semiconductor package (e.g., a millimeter (mm)-wave antenna packages) can further comprise dummification elements disposed near one or more antenna layers. Further, the dummification elements disposed near one or more antenna layers can reduce image current and thereby increasing the antenna gain and efficiency.

    Abstract: Molded electronics package cavities are formed by placing a sacrificial material in the mold and then decomposing, washing, or etching away this sacrificial material. The electronics package that includes this sacrificial material is then overmolded, with little or no change needed in the overmolding process. Following overmolding, the sacrificial material is removed such as using a thermal, chemical, optical, or other decomposing process. This proposed use of sacrificial material allows for formation of complex 3-D cavities, and reduces or eliminates the need for precise material removal tolerances. Multiple instances of the sacrificial material may be removed simultaneously, replacing a serial drilling process with a parallel material removal manufacturing process.

    Abstract: Sensing patch systems are disclosed herein. A sensing patch system includes a flexible substrate and a sensor node. The flexible substrate includes one or more substrate sensors configured to provide sensor data, one or more substrate conductors electrically coupled to a corresponding substrate sensor to conduct the sensor data provided by the corresponding substrate sensor, and a node interface. The sensor node includes a substrate interface configured to receive the node interface of the flexible substrate. The sensor node is configured to receive the sensor data provided by the substrate sensors, process the sensor data, and communicate the processed sensor data to a remote device.

    Abstract: A device for harvesting energy from fabric or clothing includes a piece of fabric or clothing. One or more piezoelectric harvesters are coupled with the piece of fabric or clothing. The piezoelectric harvesters are capable of producing electric energy in response to the movement of the piece of fabric or clothing. Additionally, the device includes one or more energy storage mediums coupled to the one or more piezoelectric harvesters. The energy storage mediums are capable of storing the energy produced by the one or more piezoelectric harvesters. Further, the method for harvesting energy from fabric or clothing involves moving a piece of fabric such that one or more piezoelectric harvesters generate electricity. The method for harvesting energy from fabric or clothing also involves storing the generated electricity in one or more energy storage mediums.
