Abstract: An improved stimulus coil for use in wireless stimulation of biological tissue (e.g., nerves, muscle tissue, etc.) and, in one exemplary implementation, to glaucoma therapy based on the wireless administration of energy to the eye of a mammalian subject (e.g., human, rodent, etc.) to reduce an elevated intraocular pressure (IOP) involving the use of an improved stimulus coil. The improved stimulus coil may be implanted in the eye of a mammalian subject or positioned on the exterior of the eye, such as (by way of example) by being disposed within a contact lens worn by a mammalian subject.

Abstract: Certain pressure sensor devices are much smaller than prior art devices, yet are at least as sensitive as the prior art devices. A capacitive pressure sensor can include a flexible substrate that permits bending of a pressure sensing region without significantly affecting operation thereof. The pressure sensor can include a flexible membrane in which an electrode is sandwiched between two layers of polymeric material. The sandwiched electrode can be extremely close to a reference electrode so as to provide for highly sensitive capacitance readings, yet the membrane can be restricted from contacting the reference electrode under high pressure condition.

Abstract: Systems and methods for wireless stimulation of biological tissue (e.g. nerves, muscle tissue, etc.) and, in one exemplary implementation, to therapy for glaucoma based on the wireless administration of energy to the eye of a mammalian subject (e.g. human, rodent, etc.) to reduce an elevated intraocular pressure (IOP) involving the use of a multi-coil wireless power transfer assembly. The multi-coil wireless power transfer assembly may be used alone or in combination with a stimulation coil that can be implanted in the eye of a mammalian subject or within a contact lens worn by a mammalian subject.

Abstract: A wireless power transfer system is disclosed. The system includes a first resonator having a first resonant frequency ωo1, a half power bandwidth Δω1, and an unloaded quality factor Qo1=ωo1/Δω1 coupled through a first coupling circuit to a power source, a second resonator having a second resonant frequency ωo2, a half power bandwidth Δω2, and an unloaded quality factor Qo2=ωo2/Δω2 coupled through a second coupling circuit to a load, the first resonator disposed a distance away from the second resonator, wherein the distance is smaller than the first and second resonant wavelengths, the first and second coupling circuits are configured so that up to a maximum achievable power transfer efficiency between the first and second resonators can be achieved, wherein Qo1 and Qo2 can be less than 100.
