I use a 9V 800mAh lipo Okcell battery to power my ESP8266 ESP-01 with a voltage regulator to change it to 3.3V. I use the ESP to detect the voltage peak from a piezoelectric when someone is running to measure the force and determine the time someone on air from the voltage graph.
The current consumption of my ESP8266 is about 75mA. From my understanding the battery can power my ESP8266 for about 8 hours because of the 20% power loss from the voltage regulator.
So for my project, can I use the piezoelectric to power my battery while im not using it. The piezoelectric I'm using is PZT type. I want to a use a force amplification frame for the piezoelectric so I use ANSYS simulation to simulate it.
Of course the data is not 100% correct but I still cannot measure the voltage and current generated from the piezoelectric as I still did not fabricate it yet.
So is there any way to use the piezoelectric to power the battery theoretically speaking. It doesn't matter if it will take 1000 hours or not, my supervisor just want to know if it still can do.
