Abstract
A power and data coupling device for medical sensors comprises a first conductive surface integrated into a medical device and configured to couple via an electric field with a second conductive surface. The second conductive surface is translatable with respect to the first conductive surface. Additionally, the first conductive surface is connected to a power source for providing power, through the electric field, to the second conductive surface. The first conductive surface also radiates a time-varying electric field that is configured to convey power to the second conductive surface. Further, the first conductive surface is connected to a pick-up that is configured to receive signals from the second conductive surface.
