Abstract: Energy harvesting enables the realisation of innovative applications where the autarkic operation of microelectronics and embedded systems is attractive or necessary. Recent advances allow reaching power potential that makes such systems a viable alternative to using batteries. In particular the potential of maintenance-free operation, measured in years if not decades, makes this technology attractive for many applications. We show that standard engineering design processes are insufficient for the design of autarkic systems and present a holistic approach for a design process and apply it to two real-world applications. These applications are an autonomous condition monitoring system for industrial drives using an inductive harvester and a self-sufficient system powering a DC-Drive using a thermoelectric generator.   The presentation shows that the application plays a key role in the design of an autarkic system. On the one hand it determines the use-case, the required functions and thus the expected energy consumption of the system. It simultaneously defines the constraints for the energy harvesting. The process therefore consists of an iterative design and modification of use-case, power generation and power consumption. Tests with prototypes demonstrate the suitability of the concepts for the two considered applications. Energy is continuously collected by the harvesters and provided by the energy aggregate at the right time. Powering an actuator requires particular care in the optimisation of the power management. The dynamic nature of actuator operation requires a strategy to ensure the necessary power level is available to complete actuator movement.
