In a recent study, researchers from the Institute of Materials Science of Barcelona (ICMAB-CSIC) developed a new concept of the thermoelectric material. A thermoelectric material is capable of transforming heat into electricity, as they convert nearly lost or hardly serviceable thermal energy in a proficient way. The study published in the Energy and Environmental Science journal. The device is produced on site in the laboratory by bacteria and it is composed of cellulose. It contained a small quantity of a conductive nanomaterial and carbon nanotubes. Environment-friendly and sustainable strategies are used to develop this device.
Concept of Circular Economy Played Crucial Role in Developing Thermoelectric Paper
Key researcher of the study, Mariano Campoy-Quiles said that they focused on cultivating energy rather than making it. he further added by saying that when bacteria is circulated in an aqueous culture medium by containing carbon nanotubes and sugar produces the nanocellulose fibers. This led to the development of the device where the carbon nanotubes were inserted.
With the help of cellulose fiber, they were able to make flexible, mechanically resistant, and deformable material. It also has high electrical conductivity due to the presence of carbon nanotubes, elucidates Anna Laromaine, one of the researchers of the study. She also added that they focused on the idea of the circular economy by using sustainable materials that are not harmful to the environment. Moreover, they can also be used in smaller quantities and can be recycled and reused.
Furthermore, these devices are likely to be used to produce electricity from remaining heat to assist sensors in agriculture and IoT applications. These devices can also be used as wearable devices, in sports or medical applications, added Campoy-Quiles.
