Thermoelectric paper produced through sustainable and environmentally friendly process - Science and technology news articles

Researchers announced the development of a new method to produce thermoelectric paper that is both sustainable and environmentally friendly. Thermoelectric paper is a material made of cellulose, containing small amounts of conductive nanomaterials that enable it to convert heat into electricity.

The scientists used bacteria to produce the nanocellulose fibers that end up forming the device. The new material has high thermal stability (it can reach up to 250 Celsius degrees) and it doesn’t use any toxic elements. Moreover, it can be easily recycled since it can be degraded by an enzymatic process converting it into glucose.

The thermoelectric paper could be used to generate electricity from residual heat, with many potential applications in technology, medicine, and even sports.
