Abstract: According to some embodiments, the present technology includes an implantable device comprising a flexible circuit including a substrate carrying a first antenna (e.g., a power harvesting antenna) configured to operate at a first frequency and a second antenna (e.g., a Bluetooth antenna) configured to operate at a second frequency different from the first frequency. The first antenna can be configured to induce a current in response to being disposed in an alternating electromagnetic field, and the second antenna can be configured to radiate radiofrequency energy to transmit data to an external device.

Abstract: Wireless power transfer devices and associated systems and methods are disclosed herein. Various embodiments of the present technology relate to devices, systems, and methods for delivering power to an implantable device, such as an implantable neuromodulation device configured to modulate a hypoglossal nerve of a patient. According to some embodiments, the present technology includes an external system comprising a control unit coupled to an external device. The external device can comprise a carrier carrying an antenna configured to conduct electrical current such that the antenna generates an electromagnetic field. When the implantable neuromodulation device is positioned within the electromagnetic field generated by the antenna, current can be induced in an antenna of the implantable neuromodulation device such that power is delivered to the implantable neuromodulation device.

Abstract: A wireless implantable neuromuscular stimulator includes an antenna for producing an induced current in response to being disposed in an electromagnetic field. The antenna includes a substrate having an upper surface and a lower surface. An upper coil including a plurality of coil turns is disposed on the upper surface of the substrate. A lower coil including a plurality of coil turns is disposed on the lower surface of the substrate. The upper and lower coils are electrically connected to each other in parallel. The parallel connection can be facilitated by a plurality of connectors that extend through the substrate and electrically connect the upper coil to the lower coil. In one example configuration, connectors connect each coil turn of the upper coil to a corresponding turn of the lower coil.

Abstract: A collapsible colander and bowl that is extendable to an expanded configuration to selectively form a colander, bowl, or container and foldable to a compact collapsed configuration for storage. The collapsible colander includes an upper rim defining an opening, a perforated bottom panel, a sidewall, a removable top lid, and a removable bottom lid. The sidewall has an upper end secured to the upper rim and a lower end secured to the perforated bottom panel. The sidewall is expandable and collapsible between a collapsed configuration and an expanded configuration. The removable top lid attaches to the upper rim, and the removable bottom lid attaches to the perforated bottom panel.
