    Abstract: Piezoelectric devices are described fabricated in packaging buildup layers. In one example, a package has a plurality of conductive routing layers and a plurality of organic dielectric layers between the conductive routing layers. A die attach area has a plurality of vias to connect to a microelectronic die, the vias connecting to respective conductive routing layers. A piezoelectric device is formed on an organic dielectric layer, the piezoelectric device having at least one electrode coupled to a conductive routing layer.

    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: Embodiments include techniques and configurations for apparatuses and methods for making an optical imaging device based on a micro mirror array. The method may include forming an array of trenches in a substrate. The array of trenches may be formed by intersecting a first plurality of walls with a second plurality of walls in the substrate. A trench of the array of trenches may be formed by adjacent walls of the first plurality of walls and intersecting adjacent walls of the second plurality of walls. A wall of the trench may include a side surface coupled with a top surface. A reflective layer may be deposited conformally to cover the side surface of the wall and to serve as a reflector. A supporting layer may be formed above the substrate, or within the array of trenches, to provide mechanical support for the array of trenches. Other embodiments may be claimed.
