Abstract:

An antenna includes a piezoelectric disc. The antenna further includes a first electrode disposed on a first surface of the piezoelectric disc and a second electrode disposed on a second surface of the piezoelectric disc that is opposite to the first surface. The first electrode and the second electrode are to receive a time-varying voltage to excite a mechanical vibration in the piezoelectric disc, and the piezoelectric disc is to radiate electromagnetic energy at a particular frequency responsive to the mechanical vibration.

Abstract:

An apparatus includes a piezoelectric thin film suspended above a carrier substrate, where the piezoelectric thin film is of one of lithium niobate (LiNbO) or lithium tantalate (LiTaO) adapted to propagate an acoustic wave in a Lamb wave mode excited by a component of an electric field that is oriented in a longitudinal direction along a length of the piezoelectric thin film. A signal electrode is disposed on, and in physical contact with, the piezoelectric thin film and oriented perpendicular to the longitudinal direction. A ground electrode disposed on, and in physical contact with, the piezoelectric thin film and oriented perpendicular to the longitudinal direction, where the ground electrode is separated from the signal electrode by a gap comprising a longitudinal distance and in which the acoustic wave resonates. A release window is formed within the piezoelectric thin film adjacent to the ground electrode.

International Classification:

H03H 9/02
H03H 9/145

Abstract:

A piezoelectric thin film (PTF) is located above a carrier substrate. The PTF may be Z-cut LiNbOthin film adapted to propagate an acoustic wave in at least one of a first mode excited by an electric field oriented in a longitudinal direction along a length of the PTF or a second mode excited by the electric field oriented at least partially in a thickness direction of the PTF. A first interdigitated transducer (IDT) is disposed on a first end of the PTF. The first IDT is to convert a first electromagnetic signal, traveling in the longitudinal direction, into the acoustic wave. A second IDT is disposed on a second end of the PTF with a gap between the second IDT and the first IDT. The second IDT is to convert the acoustic wave into a second electromagnetic signal, and the gap determines a time delay of the acoustic wave.

Abstract:

A piezoelectric thin film (PTF) is located above a carrier substrate. The PTF can be an aluminum nitride thin film adapted to propagate an acoustic wave in at least one of a first mode excited by an electric field oriented at least partially in a longitudinal direction along a length of the PTF or a second mode excited by the electric field oriented in a thickness direction of the PTF. A first interdigitated transducer (IDT) is disposed on a first end of the PTF and converts a first electromagnetic signal, traveling in the longitudinal direction, into the acoustic wave. A second IDT is disposed on a second end of the PTF with a gap between the second IDT and the first IDT. The second IDT is to convert the acoustic wave into a second electromagnetic signal, and the gap determines a time delay of the acoustic wave.

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.
