  • Patent number: 11358325
    Abstract: Methods and systems suitable for fabricating multi-layer elastic electronic devices, and elastic electronic devices formed thereby. A method of fabricating an elastomer-based electronic device includes printing a first liquid material and then a second liquid material on a fabric substrate that comprises fibers. The first and second liquid materials are sequentially printed with a three-dimensional printer that directly prints the first liquid material onto the fabric substrate so that the first liquid material wicks through some of the fibers of the fabric substrate and forms a solid matrix of an elastomer-based composite that comprises the matrix and the fabric substrate, after which the three-dimensional printer directly prints the second liquid material on the elastomer-based composite to form a film thereon. The elastomer-based composite and film are electrical components of the elastomer-based electronic device.

  • Patent number: 11362200
    Abstract: A field-effect transistor (FET) includes a fin, an insulator region, and at least one gate. The fin has a doped first region, a doped second region, and an interior region between the first region and the second region.

The interior region of the fin is formed as a superlattice of layers of first and second materials alternating vertically. The insulator layer extends around the interior region. The gate is formed on at least a portion of the insulator region. The insulator layer and the gate are configured to generate an inhomogeneous electrostatic potential within the interior region, the inhomogeneous electrostatic potential cooperating with physical properties of the superlattice to cause scattering of charge carriers sufficient to change a quantum property of such charge carriers to change the ability of the charge carriers to move between the first and second materials.
