Applications

Efficiently generating multiple electrically and spatially isolated DC power rails (along with an integrated data channel and no need for local battery buffering) from a single transmitter enables a wide range of applications.

The following are a few possible examples to illustrate the flexibility of the technology:

Simplified examples of wireless power transfer providing mechanical and electrical isolation.

Industrial

  • Replacement of expensive, failure prone mechanical connectors, in particular spring-loaded style connectors such as pogo-pins.
  • Highly cost effective, maintenance free alternative to rotary transformers or slip-ring couplers for interfacing to rotating equipment.
  • Simplification of interfacing to high vacuum systems.
  • Simplification of interfacing into sealed systems.
  • Isolation between high and low voltage systems.
  • Interfacing into harsh industrial environments, such as sensing in high temperature or caustic environments.
Wireless power transfer through the skin to a medical implant.

Medical

  • Simple and cost effective medical device durable-to-disposable interface:
    • In certain medical devices there is a disposable portion of the device consisting of sensors, pumps, electrodes, etc. that contacts the patient and cannot be reused for sanitary reasons.
    • The disposable component needs to be mechanically isolated from the rest of the system to avoid cross contamination.
    • The durable portion may need to be electrically isolated from the patient-contacting disposable part for fail-safe reasons.
    • Currently expensive, mechanically inconvenient, and failure prone sealed connectors or contact connectors are used to move power and data between the durable and disposable parts of the medical device.
    • After the disposable is disconnected, the connectors on the durable often require an involved sanitation procedure.
    • If a contact-less electrical connector existed, all of the above problems could be conveniently solved.
    • Two sealed coils brought into proximity could replace all of the sealed mechanical connectors.
  • Transcutaneously powered, permanently implantable medical technology.
    • E.g. Implanted bio-sensors powered by an externally worn wrist band.
  • Rechargeable pacemakers.
  • Simplification of bioelectronics.

Consumer

  • Wireless charging pads that operate with much higher efficiency, support multiple devices at once, and allow freedom of device placement.
  • Better efficiency for battery to battery (device to device) power transfer applications.
  • Wireless electric car charging.
    • The Nimbus Integrated solution could scale up to kW range for electric car charging.
  • Passively or temporarily powered embedded technologies.
