Our country's scientists have developed a new type of material for human body heat generation.

Turning people into "walking power banks" is expected to move from science fiction to reality. Scientists have now focused on the excess heat generated by our bodies, developing a special plastic thermoelectric thin film material that can convert heat energy into electrical energy to charge our portable electronic devices. The core indicators of this material have set the latest world record in its class. This achievement was published yesterday in the international academic journal "Science."
