  1. Emerging Technologies of Computation Montek Singh COMP790-084 Sep 27, 2011

  2. Today: Energy Harvesting Systems • 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. CEA-LETI case study • 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. CEA-LETI case study • Convert analog events (energy level change, sensor input)… • … to asynchronous digital event for controller

  5. Newcastle case study • Background: switched capacitor power converters • reconfigure topology to convert voltages

  6. Newcastle case study • Propose capacitor bank with an intelligent switching controller

  7. Newcastle case study • Piezoelectric harvesters • Experiments with different voltage converters

  8. Imperial College case study • Biosensors/harvesters • directly attached to human body
