Energy in the Small: Scaling limits for micron-size energy sources

For micron-scale Information and Communication Technology (ICT) systems, such as Internet-of Things, implantable diagnostics/therapy etc., the available volume for on-board energy supplies is very limited.
Thus, the capacity of an energy source, in terms of both energy stored and the rate at which it can deliver energy, can place severe constraints on system operation. In this talk, fundamental scaling limits for a variety of micron-size energy sources are investigated; including capacitors, galvanic and fuel cells, the supercapacitor, and radioisotope sources.
An overview of the energy available for harvesting from a variety of sources is also provided. The architectural implications including system operation will also be discussed. Each of the essential units in an ICT system (such as, e.g. storage, communication, processing, energy etc.) occupies certain volume in space, and taken together, they determine the scaling limits of an electronic system. Therefore, theoretically optimal partitioning within a fixed space envelope needs to be explored.
