Abstract :
Wireless and wearable implantable biomedical devices are ushering in a new paradigm in health care and medicine with potential to improve health outcomes at reduced cost and improved quality of life. Magneto-inductive telemetry is widely used for wireless power and data transfer. The typical inductive telemetry core consists of a pair of antenna/coils placed coaxially in space, one inside the device and one placed externally as part of the reader/interrogator. The external coil typically transmits data, which is also harvested for its power and regulated to power up the implant circuitry. One of the most important design criteria is to maximize the coupling between external and implanted coil.
