Energy budgets

Scenarios

  • Constantly on wired power
  • Periodically used on battery, else plugged in
  • Always/normally battery powered
  • Energy harvesting. Never connected to charger, should run forever

Energy harvesting

Energy harvesting rules of thumb:

Outdoor light – 10mW/cm2
Industrial temperature difference – 1-10 mW/cm2

Industrial vibration – 100µW/cm2
Human temperature difference – 25µW/cm2
Indoor light – 10µW/cm2
Human vibration – 4µW/cm2

GSM RF – 0.1µW/cm2
Wifi RF – 0.001µW/cm2

AI and Unreliable Electronics (*batteries not included).
