Scientists identify new material for wearable devices

Queensland University of Technology (QUT) researchers have identified a new material which could be used as a flexible semiconductor in wearable devices by using a technique that focuses on the manipulation of spaces between atoms in crystals.

In their study published in the journal Nature Communication, the researchers used 'vacancy engineering' to enhance the ability of an AgCu(Te, Se, S) semiconductor, to convert body heat into electricity.

Vacancy engineering is the study and manipulation of empty spaces in a crystal where atoms are missing, to influence the material's properties, such as improving its mechanical properties or optimising its electrical conductivity, or thermal properties.
