How About Other Waves for Intra Body Communication? Ultrasound Maybe?
In this talk the use of ultrasound (US) waves for communication between implants or from implant to skin will be discussed. First we will discuss US communication channel properties. Next, US based communication will be compared to communication based on RF and inductive links. These are most used today. Finally, preliminary results on a prototype point to point link based on OFDM modulated US waves will be presented.
