“…The energy sources are thermal, chemical, mechanical, electromagnetic, human-body, radioisotope, and biological energies. For example, the human body can generate energy by performing some operations like walking, jogging, heartbeat, and blood pressure [3]. There are many mechanisms available to convert mechanical to electric energy, which include, piezoelectric (PE), electromagnetic (EM), and electrostatic 5.99 V is obtained by testing the prototype and theoretical calculations.…”
