For inanimate objects, MEMS sensing is sufficiently accurate. Measuring and providing meaningful information about people, however, is significantly more complex. This challenge may be why some technologists differentiate types of sensors based on their location: off-body, on-body (wearable), and in-body (implantable or digestible), as their packaging and functionality significantly vary. Invited speakers will focus on sensors, actuators, and architectures that enable the eHealth revolution. Technologies that increase the accuracy or reliability of devices, lower manufacturing costs, and/or enable unique diagnostics or treatment will be highlighted.
