Achieving self-powered operation of an implantable sensor is difcult with current technology, despite the fact that the theoretical energy available for harvesting exceeds the theoretical energy required. Moreover, the design and realisation of such sensors nodes is a multi-domain task, requiring global system modelling and optimisation. This paper addresses how such systems can be modelled and optimised by considering both the individual subsystems and their interdependence. The subsystems considered are: an energy-harvesting generator, power converter and a radio link. Optimising these subsystems individually would result in a low overall system performance, but a global optimisation would have too many parameters. In order to make the optimisation and design practical it is suggested that the system is partitioned at the interface betwen the power supply output and the load circuitry, allowing the optimisation to be done in two parts whilst still nding a global optimum. Finally, we consider the dependence of power issues on device size, and show that effective performance from a body sensor node is achievable for a device volume in the cubic millimetres range. |
