The concept encompasses a variety of generation systems intended to supply small amounts of power to keep portable electronics in a good state of charge through natural motions of the body.
[2] Emergency workers like firemen and paramedics could use chest-implanted sensors to create a floor plan of unfamiliar buildings; making a rookie perform his job as efficiently as a veteran.
[citation needed] The environmental burden of disposing used batteries has contributed to e-waste; something that wearable generators may drastically reduce.
However, a recent study has taken on this challenge and discovered a way of modifying thermoelectric generators in order to adapt to the human body, making them more comfortable to wear.
[7] The technique produces a record-high open-circuit voltage and allows customers to tailor the device to specific thermal and mechanical conditions.
