  • Method of adhering a microelectromechanical (MEMS) device to a flexible fabric substrate
    Patent number: 12285083
    Abstract: Radial-armed thin-film bilayers are designed and fabricated from a metal and an oxide to produce grippers that interact with the yarns or fibers of the fabric and form a mechanical tangle attachment to the fabric. MEMs devices attached to the grippers enable the MEMs devices to be adhered to a flexible and/or extensible fabric. Fabrics comprise conventional textile, smart textiles, functional fibers or other smart materials. The fabrics thus incorporate wearable sensors, medical devices, and other functional MEMs for commercial, biomedical, industrial and scientific applications.
    Type: Grant

  • ROBOTIC SYSTEMS FOR ADDITIVE MANUFACTURING
    Publication number: 20230211558
    Abstract: Systems and methods for additive manufacturing. In some examples, a system includes a frame defining an interior volume and an overhead robotic arm suspended from a gantry on a ceiling of the frame. The system includes manufacturing subsystems located within the interior volume of the frame. The system includes a control system configured for controlling the overhead robotic arm for parts movement among additive manufacturing processes using the manufacturing subsystems. The manufacturing subsystems can include one or more of: a microassembly station, an aerosol jetting print station, an intense pulsed light (IPL) photonic sintering station, a fiber weaving station, and a 3D printing station.
