A Korean analysis staff has developed a novel thermoelectric materials and generator (TEG) that leverages sponge-like carbon nanotube (CNT) constructions, enhancing the restrictions of natural thermoelectric supplies whereas retaining flexibility. The ensuing system is anticipated to be helpful in powering small-scale wearable sensors by way of thermal power harvesting.
The analysis is revealed within the journal Carbon Power.
Led by Drs. Mijeong Han and Younger Hun Kang on the Korea Analysis Institute of Chemical Know-how (KRICT), the staff mixed carbon nanotubes with Bi0.45Sb1.55Te3 (BST) in a porous foam construction to maximise thermoelectric efficiency.
Whereas typical thermoelectric supplies are sometimes metal-based and inflexible, the usage of CNTs permits for gentle weight and mechanical flexibility—though earlier makes an attempt have resulted in low thermoelectric efficiency and poor sturdiness.
To beat these challenges, the staff developed a proprietary fabrication approach that transforms CNTs into bulk foams reasonably than skinny movies. This was achieved by heating and solidifying a…
