Wireless implantable medical devices have transfigured the field of biomedical engineering with the invention of adequate power supplies. Conflicting the commonly used RF and inductive methods, ultrasonic transmission of power circumvents problems associated with low inefficiencies and electromagnetic coupling offering application for a selection of data frequencies. Moreover, it prevails over the demerits of wireless power transfer through inductive coupling. In this dissertation, the candidate explored a novel ultrasonic link for wireless power and data transfer deep in the body, integrated with MEMS ultrasonic transducers, especially intended for neuro-stimulator that is to be implanted deep in a patient's body to function as, for example the pacemaker, bladder pressure sensor, implantable blood flow monitoring system, neural stimulation system, defibrillators, circulatory assist devices, etc.
