  • Publication number: 20200368064
    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.

  • Publication number: 20200237218
    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.
