2. Applications today has a limited lifetime The owner of +20 years data provision technology will be in an unique market position.

3. How long time is 20 years ? Is this totally outdated and beyond use ?

4. Source: Powercast The Little Problem Systems at sleep consume all the power Harvest Energy for Sleep time

5. + 20 Years Applications will make sense in the following areas: Maintenance Long term storage Monitoring

7. Maintenance

8. Long Term Storage

9. Typical Usage Maintenance Long term storage Monitoring

10. Limitations 1 mW at 10°C 100 mW at 2,5 G 20 mW 143 mW 100 mW

11. Batteries vs. Super Caps 300 mAh @ 1.2 V = 360 J 10 F @ delta V 2 V = 40 J

12. The Power Conditioner Harvest tiny amount's of Energy Build of sufficient charge Use the Energy in bursts

13. Case: Traffic counting Approximations are as good as or better than real values (reduced noise)

14. Boundary conditions Installation Start up Operation Life time for the entire system

15. Times they are changing

16. Best practices Keep it simple Use 100% time on 20% of the requirements Sketch it Get user reaction on duty cycled functionality

17. Brunata - DELTA Energi harvesting prototype: The battery was removed and the circuit is now driven from the heat difference between the radiator and the room.

18. Bell M412 Pitch Link The system was able to transmit realtime data about the stress on vital components No batteries was needed Available power exceeded need 300 uW harvested during level flight 250 uW needed for realtime operation Source: MicroStrain

19. Torro Espacio Madrid 4200 Switches which must be rearranged on demand Uses en-ocean motion harvestere Saves 42.000 batteries in 25 years Source: En-Ocean

21. Structural Health Monitoring in Los Alamos The bridge needs to be “cleared” after earthquaktes. Bridge health can be monitored by sensors (strain, ultra sound, etc.) Experiments shows that a 0.1F 3.3V C can be charged in 200s Wireless TX and RX 256 bytes (RS-232) 5.2 m LA-14314-MS Feb 2007 Los Alamos National Laboratory

22. Benefits from a Early Entry You will gain first hands experience You will set the std. and be in control in your market The technology is there and you will be able to influence what there is produced You will be able to get all available components for a while, which will bring you further in front

23. DELTA Energy Harvesting Expertise We have the required knowledge about: Mechanical Design Thermo dynamics Micro-Electronic Embedded Software And we are used to combine the expertices

24. It is possible Thomas Sørensen ths@delta.dk
