  • Patent number: 10727804
    Abstract: An integrated circuit is a layered device, on a semiconductor substrate, which contains metal electrodes that sandwich a piezoelectric layer, followed by a magnetostrictive layer and a metal coil. The metal electrodes define an electrical port across which to receive an alternating current (AC) voltage, which is applied across the piezoelectric layer to cause a time-varying strain in the piezoelectric layer. The magnetostrictive layer is to translate the time-varying strain, received by way of a vibration mode from interaction with the piezoelectric layer, into a time-varying electromagnetic field. The metal coil, disposed on the magnetostrictive layer, includes a magnetic port at which to induce a current based on exposure to the time-varying electromagnetic field generated by the magnetostrictive layer.

  • Publication number: 20200212873
    Abstract: A micro-resonator includes a first electrode positioned on a piezoelectric plate at a first end of the piezoelectric plate, the first electrode including a first set of fingers and a second electrode positioned on the piezoelectric plate at a second end of the piezoelectric plate. The second electrode including a second set of fingers interdigitated with the first set of fingers with an overlapping distance without touching the first set of fingers, the overlapping distance being less than seven-tenths the length of one of the first set of fingers or the second set of fingers. At least one of the first end or the second end of the piezoelectric plate may define a curved shape.

  • Publication number: 20200197223
    Abstract: Disclosed are devices, systems, and methods for restoring vision to a subject. In one embodiment, the vision restoration device comprises a projector configured to project one or more digital images onto a central retina of the subject and one or more lenses coupled to the projector and configured to focus the one or more digital images. The vision restoration device can also comprise an extraocular component configured to be implanted within the subject and comprising one or more processors programmed to execute instructions stored in a memory to wirelessly receive the one or more digital images from an extracorporeal device. The intraocular projection component can be connected or coupled to the extraocular component by a trans-scleral communication wire configured to cross the sclera of the eye. The trans-scleral communication wire is configured to transmit digital data between the extraocular component and the intraocular projection component.

  • Publication number: 20190334568
    Abstract: An apparatus includes parallel delay lines, each exhibiting a delay; a first set of switches for each port of a first set of ports, each of which is to selectively couple a port of the first set of ports to first ends of the delay lines; a second set of switches for each port of a second set of ports, each of which to selectively couple a port of the second set of ports to second ends of the delay lines. A signal source generates a series of clock signals that are sequentially time delayed between the first set of switches and the second set of switches, where an input signal at one of the first or second sets of ports travels from the one of the first or second sets of ports to an output port of opposite set of ports over the delay lines.

  • Publication number: 20190131953
    Abstract: A piezoelectric thin-film suspended above a carrier substrate. An input interdigital transducer (IDT) having first interdigitated electrodes is disposed at different locations along the horizontal axis and on the first side of the piezoelectric thin-film. Each opposing pair of the first interdigitated electrodes is to selectively transduce a particular frequency range of an input electrical signal that varies in frequency over time into an acoustic wave of a laterally vibrating mode based on a pitch between electrodes of the opposing pair. An output IDT that includes second interdigitated electrodes is disposed at different locations along the horizontal axis and on the second side of the piezoelectric thin-film. Each opposing pair of the second interdigitated electrodes is to convert the acoustic wave transduced by the respective opposing pair of the first interdigitated electrodes into a compressed pulse.

  • Patent number: 10168221
    Abstract: An infrared (IR) detector comprises a radio frequency (RF) resonator including a bottom electrode to provide acoustic excitation, a piezoelectric layer connected to the bottom electrode and suspended over a cavity defined within a semiconductor substrate, and a top layer comprising a mid-IR metamaterial and which is connected to the piezoelectric layer of the RF resonator. The top layer and the piezoelectric layer are sized to impedance match with a particular IR wavelength, to minimize reflection and maximize absorption of a particular IR wavelength, and thus make the top layer polarization sensitive to the particular IR wavelength.
