Next-Generation Wireless Power Receiver Coil for Implantable Neuromodulation Devices

A novel wireless power receiver coil for implantable neuromodulation devices, featuring dynamically adjustable resonant frequencies, real-time power transfer optimization, and integrated sensors and energy harvesting capabilities to enhance power transfer efficiency and minimize tissue heating.

The original patent's wireless power receiver coil design has limitations in terms of power transfer efficiency and tissue heating. The new inventive concept addresses these limitations by introducing advanced features such as dynamically adjustable resonant frequencies, real-time power transfer optimization, and integrated sensors and energy harvesting capabilities.

The next-generation wireless power receiver coil comprises a dynamically adjustable resonant frequency, which is adjusted in real-time based on the proximity of the transmitter coil to optimize power transfer efficiency. The coil is integrated with a sensor for detecting changes in the surrounding tissue, and the power transfer is adjusted based on the sensor data to minimize tissue heating. Additionally, the coil features a built-in energy harvesting module, which captures and converts ambient energy from the surrounding tissue into electrical energy to supplement the wirelessly transferred power. The coil's shape and orientation can be dynamically adjusted using a micro-electromechanical system (MEMS) to further optimize power transfer efficiency.

The new claims introduce novel features such as dynamically adjustable resonant frequencies, real-time power transfer optimization, and integrated sensors and energy harvesting capabilities, which are not present in the original patent. These features provide a significant improvement in power transfer efficiency and tissue heating reduction, making the new inventive concept non-obvious and innovative.

Alternative embodiments of the inventive concept could include varying the design of the sensor, energy harvesting module, and MEMS system to optimize power transfer efficiency and tissue heating reduction. Additionally, the coil's shape and size could be modified to accommodate different implantation sites and medical devices.

The next-generation wireless power receiver coil has significant commercial potential in the neuromodulation device market, particularly in applications such as deep brain stimulation, spinal cord stimulation, and cochlear implants. The improved power transfer efficiency and tissue heating reduction offered by the new inventive concept could lead to increased adoption and market share in these industries.
