My product is a vibration monitoring system. I would be interested if I can use the vibration for energy harvesting and how should I do it.
You can connect vibration energy using the S6SAE101A00SA1002 Solar-Powered IoT Device Kit.
Please refer to "6.1.5 Vibration Energies Connection (Optional)" of the user guide.
Note that you should use external diodes with S6AE10xA device to convert AC to DC.
