I am prototyping wood step which is able to power itself.
I will describe the working model below:
When somebody stands on this step , it will force piezoelectric module to generate electricity. I have 300x1000mm space to install piezoelectric modules (as much as I need, I can use entire space) to generate enough electricity to power up 1 meter LED strip for 5/4 seconds.
This led strip won't work every time when you go up or go down the stairs, but I don't want to waste generated energy so this energy should be accumulate also and power LED any other time when I want to do it.
Energy required for a power LED strip (about 2 Watts) should be generated by standing on the step once. All piezoelectric modules will be pressed at the same time.
I need a project of this system ( only electric) to charge capacitor and power up led strip.
