Case studies ◦ CEA-LETI (power management) ◦ Univ. of Newcastle (power management) ◦ Imperial College (biosensors) Next time: ◦ UCLA (solar) ◦ Caltech (acoustic) ◦ Challenges and Benefits ◦ Open questions
3
Managy ◦ power management subsystem harvested power vs. stored power low/medium/high power modes ◦ In center is digital power controller ◦ multiple harvestors ◦ multiple sensors ◦ multiple processing “loads”
4
Convert analog events (energy level change, sensor input)… … to asynchronous digital event for controller
5
Background: switched capacitor power converters ◦ reconfigure topology to convert voltages
6
Propose capacitor bank with an intelligent switching controller
7
Piezoelectric harvesters Experiments with different voltage converters
8
Biosensors/harvesters ◦ directly attached to human body
