The heat from the human body could be harvested to run low power electronic devices
Efforts to capture energy from the human body usually focus on harnessing the kinetic energy of the body’s movement. However the human body is also generating energy in the form of heat that could also be used to run low power electronic devices. New energy-scavenging systems under development at MIT could generate electricity just from differences in temperature between the body (or other warm object) and the surrounding air.
