Title: Tsunekazu Saigo: Innovator in Thermoelectric Materials
Introduction
Tsunekazu Saigo is a prominent inventor based in Matsubara, Japan. He has made significant contributions to the field of thermoelectric materials, holding a total of 7 patents. His work focuses on developing efficient materials that can convert heat into electricity, which is crucial for sustainable energy solutions.
Latest Patents
One of his latest patents is titled "Thermoelectric conversion material and method of producing the same." This invention describes a thermoelectric conversion material formed of a polycrystal structure of crystal grains composed of a silicon-rich phase. An added element-rich phase is deposited at the grain boundary, resulting in an extremely large Seebeck coefficient and low thermal conductivity. This innovation dramatically raises the thermoelectric conversion rate and utilizes silicon, an abundant resource, minimizing environmental pollution.
Another notable patent is "Thermoelectric conversion material, and method for manufacturing same." This patent details a silicon-based polycrystal powder that contains no more than 30 at % Ge, C, Sn, or similar elements that do not generate carriers. The powder has a crystal structure with at least 80 at % silicon and a grain boundary phase where an added element is precipitated. This mixture is combined with a clathrate compound powder, which has low thermal conductivity and electrical resistivity, and subjected to hot compression molding to create a composite structure.
