Here are the minutes: https://blogs.epfl.ch/productdesignteam8/documents/Minutes/Minutesmeeting11.pdf
Updates after the tests with the coil:
Energy production: about 5mW / 20mW per coil. (walking / running)
Versus energy consumption of the LED: 600mW / 60mW (power safe)
Additionally, the conversion electronics consume a lot, result: no power left for the LED.
- Loic: Find out how to easily replace the LED by a less consuming LED / modify the driving circuit to have different duty cycles
-Micha: Check a low-power chip dedicated to energy harvesting. Check if it's still possible to do a last-minute PCB. The boost we chose sucks (new product on the market), even for normal battery applications it leaks too much. Give a bad feedback on mouser. Implement solution on the PCB for disabling the electronics when we don't need them.
Our technology still has a future, it's very innovative passive energy harvesting. There is more research to do!
Here is the feedback and some comments from the jury on your mid-term presentation.
Some class statistics, FYI:
- Max grade: 4.44/5 (Good job! :))
- Min grade: 2.88/5
- Average grade: 3.80/5
Let me know if you guys have any questions. See you on Friday,
