Energy Harvesting with Electro Magnetic Micro Generator

Energy Harvesting (EH) from human or environmental sources has proven to be an effective alternative or complement for battery charging or other uses.

As light, thermal, mechanical and RF are major sources in EH and among them, mechanical energy from wind, waves, vibrations, etc. is commonly existed in our daily life.

In this new thread the energy will be harvested by using micro generators. This research project addresses the development of a unique EH circuit capable of fulfilling our needs.

Jagau one question: to extend the power of your micro generator did you maybe think about it to use the Pulse from the 10uF Cap to pulse your triple 80uH Coilcapacitor project ?

could you test this , as I´m waiting for parts...

The micro generator isn't powerful enough to power the 3 coils circuit. ugen produces only 0.5 micro-joules per flash (C Vsquare / 2 X DTC)

while the 3 coils circuit requires 30 milli-joules, (3 V X .010ma x 1 sec )

you can play with the resistive voltage divider to vary the flash speed like Fighter did.

Happy experimenting.

just a precision in 3 coils circuit coils are in millihenry = 0.080H

not in uH 0.00008H like you wrote.

ok understand. yes 80milliHenry ! thank you. How much Joule we need to "ping" the 3 coiler ? who to change your Harvester to give the needed energy ? change the 10uF to lets say 100uF ?

Replying to hanskammler

I also change your Harvester micro generator with this

I don't understand what you're saying. My micro-generator doesn't use any batteries; it's powered by ambient energy.
Your proposal uses a large battery?

No possible comparison.

forget the battery. instead I had the 4x uf4007 and a 10uF cap connected. I showed you this only for the avalanche switch effekt. the base is not connected and when U>15.8 my bc547 will close briefly and an imense Flash from led occured.
