Contactless inductive-operation microcircuits for medical applications

The contactless inductive operation device is a circuit which can operate through inductive coupling for both powering and read/write operation. Neither wires nor battery are required, so a microcircuit that is physically unavailable, as it is when implanted in the human body, can be accessed for operation/information exchange. The only component to be added is one microcoil. A one-chip implementation of the above concepts has already been produced with success for the read operation only. The write operation has still to be verified on a single chip, but it is believed that no major barrier exists.<>
