Human machine interface with dedicated software using sensors for energy harvesting. Nowadays Human-machine interfacing (HMI) motivated many studies to develop systems and devices that were able to transfer analog commands from the user's body to machines through movements. Natural evolution provided human beings with one of the most efficient mechanical interfaces with the outer environment through hands. People use their hands to interact with tools and other people every day. People in nowadays use finger movement in hand to generate energy. In this model to harvest the energy through finger movements with the support of microcontroller, piezoelectric sensor, 3-axis accelerometer.
