• Phone must be placed directly on the pad

• Orientation is critical to charging

• Phone must have a capture coil (embedded, or as a sleeve)

• 5W at 50% efficiency

So…is this technology safe?

So…is this technology safe?

• No adverse health risks to body

• No adverse affect on embedded devices

• Minimal energy transfer to “off resonant” devices

• “Non-radiative” electromagnetic field

• Meets international safety guidelines for human

exposure

• Actually in development for implanted medical

devices

Any affect on people??

So…is this technology safe?

Wireless Interior Future Concept

They're already here….

So… ….How might this technology change connectors?

“Looks like we may need to change our technical knowledge!”

• Eliminate Contact Resistance

• Eliminate terminal mating

forces

• No Plating or Materials

concerns

• No fretting issues

• No arc faults

• No Lubricants

• No contact erosion

• No contact wear

In Conclusion

• Wireless Power applications are increasing

• What was not practical in the past is being done

today

• What is not practical today will be practical in the

future

• Technology will open up new potential applications

• Our scope of technology of connections will expand

• Don’t hold your breath…..It will take time

Thank You!
