Hey guys, I have been thinking of creating a flashlight that is powered by piezoelectric (pressure) energy. I have watched several videos so far and I noticed that in order to actually generate electricity, one would have to constantly tap it rapidly in order to power an LED light. However, I want to try to minimize the input requirements of rapidly tapping the pizoelectrical sensor. I know that pizoelectrical sensors generate electricity by being deformed so I was thinking of ways to try to still deform it and generate electricity with smaller and more gentle/effortless movement. The main idea is that I want to reduce the effort needed by the user to power up the flashlight, without rapidly charging it for immediate use or charging the device. -I was thinking of trying of either trying to use small stroking/rubbing movements where a small flexible mat with multiple points at the bottom can deform the sensor. If that is not enough force, then I would have to figure out someway to get mechanical advantage. -Some kind of small wheel has some points on it and when you roll the wheel back and forth, the teeth at the end would deform the pizoelectrical sensor. -Some sort of mechanical advantage to reduce the tapping force of the user and using mechanical advantage to raise the force of the minimize tapping motion to meet the LED's requirements. I wonder if a spring can be useful here. Will these ideas work? Do you have any better methods I can use?
